Stripe separates prohibited illegal weapons and accessories (plus improperly marked replicas of modern firearms, including toys) from restricted "Legal firearms and other weapons." The restricted bucket, marked limited availability with a sales-team contact note, lists firearms including rifle
PayPal's Acceptable Use Policy prohibits using PayPal for activities that relate to transactions involving ammunition, firearms, or certain firearm parts or accessories, or certain weapons or knives regulated under applicable law. That is broader than "complete guns only." Accessory and regulated-knife SKUs can trigger the same AUP bucket depending on how PayPal interprets "certain" in a given case. Pre-approval charts elsewhere in the AUP do not rewrite that firearms prohibition paragraph.
Square (flat prohibition on firearms, parts, ammo, and weapons)
Square's General Terms of Service restrict sellers from using the Services for the sale of firearms, firearm parts, ammunition, weapons, or other devices designed to cause physical harm. That wording is categorical for Square rails. Treat Square as a non-starter for firearms, firearm parts, and ammunition catalogs unless Square itself provides a current written exception (do not invent one from secondary blogs).
Shopify Payments eligibility guidance states that businesses and products that require regulatory approval or compliance, including firearms, holsters, ammunition, or weapons, are not eligible. Separately, Shop channel prohibited product types include weapons, ammunition, explosives, or related accessories and combat equipment. Shopify's Acceptable Use Policy emphasizes that merchants must follow platform, partner, and payment-supply-chain rules, and that Shop has its own eligibility criteria.

Regulatory definitions come from 27 CFR 478.11, 27 CFR 478.12, and National Firearms Act (NFA) terms in 27 CFR 479.11, with the ATF Firearms hub as the agency orientation page.
Under 27 CFR 478.11, a firearm is any weapon (including a starter gun) that will, is designed to, or may readily be converted to expel a projectile by the action of an explosive; the frame or receiver of any such weapon; any firearm muffler or firearm silencer; or any destructive device. Antique firearms are excluded from that GCA-facing definition as stated in the regulation. The same section defines ammunition to in
27 CFR 478.12 defines frame and receiver in detail for handguns and for rifles, shotguns, and other projectile weapons. It also covers silencer frames or receivers (generally the outer tube or principal housing for baffles or expansion chambers, not a removable end cap) and partially complete, disassembled, or nonfunctional frames or receivers, including certain parts kits that are designed to or may readily be completed to function as a frame or receiver. Raw unmachined billets that have not reached a clearly identifiable unfinished-component stage are carved out, subject to the regulation's examples and the Director's classification factors (templates, jigs, tools, instructions, marketing materials).
NFA "firearm" categories in 27 CFR 479.11 include short-barreled shotguns and rifles (with stated length thresholds), weapons made from shotguns or rifles below stated overall or barrel lengths, "any other weapon," machine guns, mufflers or silencers, and destructive devices. Ecommerce teams should treat NFA items as a distinct compliance and licensing stack, not as ordinary accessories.
For storefront taxonomy, practical tags that track the regulation rather than marketing copy.
clude cartridge cases, primers, bullets, or propellent powder designed for use in any firearm other than an antique firearm (with stated shotgun-shell carve-outs).

By E-commerce 4 Internet Marketers Editorial
Explainer. Website owners and developers who sell "tactical" and outdoor catalogs often mix regulated firearms, ammunition, accessories, knives, and camping gear in one storefront. Mainstream payment platforms publish prohibited or restricted business lists that treat much of that mix as off-limits or revi
Processor patterns are limited to Stripe's Prohibited and Restricted Businesses (last updated 2026-05-13), PayPal's Acceptable Use Policy, Square's General Terms of Service, Braintree's Acceptable Use Policy, Shopify Payments eligibility, and Shop channel prohibited products. This is not le
ATF rules answer whether an item is a firearm, ammunition, frame or receiver, or NFA firearm under federal firearms law. Processor and platform contracts answer whether that item may ride that company's payment rails. A lawful FFL retail sale can still violate PayPal, Square, Braintree, or Shopify Payments rules. A camping backpack that is not a firearm under ATF definitions can still sit next to restricted SKUs that poison a mainstream MID if the catalog is disclosed poorly.
Operators who collapse those maps into one "tactical equals high risk" slogan underwrite themselves incorrectly. Operators who assume "accessories are fine on Stripe" without reading Stripe's restricted-weapons language do the same. Build catalog risk tags against both maps before choosing a gateway.
What ATF definitions put in the firearms bucket
gal, licensing, shipping, or underwriting advice.
Public lists are not MCC charts, and they do not guarantee approval or denial for any merchant.
Under 27 CFR 478.11, a firearm is any weapon (including a starter gun) that will, is designed to, or may readily be converted to expel a projectile by the action of an explosive; the frame or receiver of any such weapon; any firearm muffler or firearm silencer; or any destructive device. Antique firearms are excluded from that GCA-facing definition as stated in the regulation. The same section defines ammunition to in
27 CFR 478.12 defines frame and receiver in detail for handguns and for rifles, shotguns, and other projectile weapons. It also covers silencer frames or receivers (generally the outer tube or principal housing for baffles or expansion chambers, not a removable end cap) and partially complete, disassembled, or nonfunctional frames or receivers, including certain parts kits that are designed to or may readily be completed to function as a frame or receiver. Raw unmachined billets that have not reached a clearly identifiable unfinished-component stage are carved out, subject to the regulation's examples and the Director's classification factors (templates, jigs, tools, instructions, marketing materials).
NFA "firearm" categories in 27 CFR 479.11 include short-barreled shotguns and rifles (with stated length thresholds), weapons made from shotguns or rifles below stated overall or barrel lengths, "any other weapon," machine guns, mufflers or silencers, and destructive devices. Ecommerce teams should treat NFA items as a distinct compliance and licensing stack, not as ordinary accessories.
For storefront taxonomy, practical tags that track the regulation rather than marketing copy.
clude cartridge cases, primers, bullets, or propellent powder designed for use in any firearm other than an antique firearm (with stated shotgun-shell carve-outs).
A firearm muffler or firearm silencer includes any device for silencing, muffling, or diminishing the report of a portable firearm, including combinations of parts designed or redesigned and intended for assemblin
- GCA firearm / frame-receiver / complete weapon. Serial-number and FFL transfer workflows usually apply. Do not treat unfinished kits as "just parts" without counsel review against 478.12.
- Ammunition and ammunition components as defined in 478.11.
- NFA items (silencers, short-barreled configurations, machine guns, destructive devices, AOWs) under 479.11.
- Non-firearm hardware that marketing calls "tactical" (optics mounts, apparel, packs) but that is not itself a firearm under those definitions.
- Knives and other weapons governed primarily by state and local law, and by processor knife/weapon clauses rather than ATF frame-or-receiver definitions.
Patterns below are typical public-policy patterns, not underwriting outcomes. Each provider can update lists, apply jurisdiction carve-outs, and still decline a merchant whose disclosed mix looks different from the website copy.
Stripe (restricted, limited availability for legal firearms and other weapons)
Stripe separates prohibited illegal weapons and accessories (plus improperly marked replicas of modern firearms, including toys) from restricted "Legal firearms and other weapons." The restricted bucket, marked limited availability with a sales-team contact note, lists firearms including rifle
PayPal's Acceptable Use Policy prohibits using PayPal for activities that relate to transactions involving ammunition, firearms, or certain firearm parts or accessories, or certain weapons or knives regulated under applicable law. That is broader than "complete guns only." Accessory and regulated-knife SKUs can trigger the same AUP bucket depending on how PayPal interprets "certain" in a given case. Pre-approval charts elsewhere in the AUP do not rewrite that firearms prohibition paragraph.
Square (flat prohibition on firearms, parts, ammo, and weapons)
Square's General Terms of Service restrict sellers from using the Services for the sale of firearms, firearm parts, ammunition, weapons, or other devices designed to cause physical harm. That wording is categorical for Square rails. Treat Square as a non-starter for firearms, firearm parts, and ammunition catalogs unless Square itself provides a current written exception (do not invent one from secondary blogs).
Shopify Payments eligibility guidance states that businesses and products that require regulatory approval or compliance, including firearms, holsters, ammunition, or weapons, are not eligible. Separately, Shop channel prohibited product types include weapons, ammunition, explosives, or related accessories and combat equipment. Shopify's Acceptable Use Policy emphasizes that merchants must follow platform, partner, and payment-supply-chain rules, and that Shop has its own eligibility criteria. A Shopify storefront can still exist while Shopify Payments and Shop remain unavailable for those SKUs. That

Regulatory definitions come from 27 CFR 478.11, 27 CFR 478.12, and National Firearms Act (NFA) terms in 27 CFR 479.11, with the ATF Firearms hub as the agency orientation page.
By E-commerce 4 Internet Marketers Editorial
Explainer. Website owners and developers who sell "tactical" and outdoor catalogs often mix regulated firearms, ammunition, accessories, knives, and camping gear in one storefront. Mainstream payment platforms publish prohibited or restricted business lists that treat much of that mix as off-limits or revi
Processor patterns are limited to Stripe's Prohibited and Restricted Businesses (last updated 2026-05-13), PayPal's Acceptable Use Policy, Square's General Terms of Service, Braintree's Acceptable Use Policy, Shopify Payments eligibility, and Shop channel prohibited products. This is not le
ATF rules answer whether an item is a firearm, ammunition, frame or receiver, or NFA firearm under federal firearms law. Processor and platform contracts answer whether that item may ride that company's payment rails. A lawful FFL retail sale can still violate PayPal, Square, Braintree, or Shopify Payments rules. A camping backpack that is not a firearm under ATF definitions can still sit next to restricted SKUs that poison a mainstream MID if the catalog is disclosed poorly.
Operators who collapse those maps into one "tactical equals high risk" slogan underwrite themselves incorrectly. Operators who assume "accessories are fine on Stripe" without reading Stripe's restricted-weapons language do the same. Build catalog risk tags against both maps before choosing a gateway.
What ATF definitions put in the firearms bucket
gal, licensing, shipping, or underwriting advice.
Public lists are not MCC charts, and they do not guarantee approval or denial for any merchant.
Under 27 CFR 478.11, a firearm is any weapon (including a starter gun) that will, is designed to, or may readily be converted to expel a projectile by the action of an explosive; the frame or receiver of any such weapon; any firearm muffler or firearm silencer; or any destructive device. Antique firearms are excluded from that GCA-facing definition as stated in the regulation. The same section defines ammunition to in
27 CFR 478.12 defines frame and receiver in detail for handguns and for rifles, shotguns, and other projectile weapons. It also covers silencer frames or receivers (generally the outer tube or principal housing for baffles or expansion chambers, not a removable end cap) and partially complete, disassembled, or nonfunctional frames or receivers, including certain parts kits that are designed to or may readily be completed to function as a frame or receiver. Raw unmachined billets that have not reached a clearly identifiable unfinished-component stage are carved out, subject to the regulation's examples and the Director's classification factors (templates, jigs, tools, instructions, marketing materials).
NFA "firearm" categories in 27 CFR 479.11 include short-barreled shotguns and rifles (with stated length thresholds), weapons made from shotguns or rifles below stated overall or barrel lengths, "any other weapon," machine guns, mufflers or silencers, and destructive devices. Ecommerce teams should treat NFA items as a distinct compliance and licensing stack, not as ordinary accessories.
For storefront taxonomy, practical tags that track the regulation rather than marketing copy.
clude cartridge cases, primers, bullets, or propellent powder designed for use in any firearm other than an antique firearm (with stated shotgun-shell carve-outs).
A firearm muffler or firearm silencer includes any device for silencing, muffling, or diminishing the report of a portable firearm, including combinations of parts designed or redesigned and intended for assemblin
- GCA firearm / frame-receiver / complete weapon. Serial-number and FFL transfer workflows usually apply. Do not treat unfinished kits as "just parts" without counsel review against 478.12.
- Ammunition and ammunition components as defined in 478.11.
- NFA items (silencers, short-barreled configurations, machine guns, destructive devices, AOWs) under 479.11.
- Non-firearm hardware that marketing calls "tactical" (optics mounts, apparel, packs) but that is not itself a firearm under those definitions.
- Knives and other weapons governed primarily by state and local law, and by processor knife/weapon clauses rather than ATF frame-or-receiver definitions.
Patterns below are typical public-policy patterns, not underwriting outcomes. Each provider can update lists, apply jurisdiction carve-outs, and still decline a merchant whose disclosed mix looks different from the website copy.
Stripe (restricted, limited availability for legal firearms and other weapons)
Stripe separates prohibited illegal weapons and accessories (plus improperly marked replicas of modern firearms, including toys) from restricted "Legal firearms and other weapons." The restricted bucket, marked limited availability with a sales-team contact note, lists firearms including rifle
PayPal's Acceptable Use Policy prohibits using PayPal for activities that relate to transactions involving ammunition, firearms, or certain firearm parts or accessories, or certain weapons or knives regulated under applicable law. That is broader than "complete guns only." Accessory and regulated-knife SKUs can trigger the same AUP bucket depending on how PayPal interprets "certain" in a given case. Pre-approval charts elsewhere in the AUP do not rewrite that firearms prohibition paragraph.
Square (flat prohibition on firearms, parts, ammo, and weapons)
Square's General Terms of Service restrict sellers from using the Services for the sale of firearms, firearm parts, ammunition, weapons, or other devices designed to cause physical harm. That wording is categorical for Square rails. Treat Square as a non-starter for firearms, firearm parts, and ammunition catalogs unless Square itself provides a current written exception (do not invent one from secondary blogs).
Shopify Payments eligibility guidance states that businesses and products that require regulatory approval or compliance, including firearms, holsters, ammunition, or weapons, are not eligible. Separately, Shop channel prohibited product types include weapons, ammunition, explosives, or related accessories and combat equipment. Shopify's Acceptable Use Policy emphasizes that merchants must follow platform, partner, and payment-supply-chain rules, and that Shop has its own eligibility criteria. A Shopify storefront can still exist while Shopify Payments and Shop remain unavailable for those SKUs. That

Explainer. Website owners and developers who sell "tactical" and outdoor catalogs often mix regulated firearms, ammunition, accessories, knives, and camping gear in one storefront.

ATF rules answer whether an item is a firearm, ammunition, frame or receiver, or NFA firearm under federal firearms law. Processor and platform contracts answer whether that item may ride that company's payment rails. A lawful FFL retail sale can still violate PayPal, Square, Braintree, or Shopify Payments rules. A camping backpack that is not a firearm under ATF definitions can still sit next to restricted SKUs that poison a mainstream MID if the catalog is disclosed poorly.
Operators who collapse those maps into one "tactical equals high risk" slogan underwrite themselves incorrectly. Operators who assume "accessories are fine on Stripe" without reading Stripe's restricted-weapons language do the same. Build catalog risk tags against both maps before choosing a gateway.
What ATF definitions put in the firearms bucket
gal, licensing, shipping, or underwriting advice.Public lists are not MCC charts, and they do not guarantee approval or denial for any merchant.
Under 27 CFR 478.11, a firearm is any weapon (including a starter gun) that will, is designed to, or may readily be converted to expel a projectile by the action of an explosive; the frame or receiver of any such weapon; any firearm muffler or firearm silencer; or any destructive device. Antique firearms are excluded from that GCA-facing definition as stated in the regulation. The same section defines ammunition to in
27 CFR 478.12 defines frame and receiver in detail for handguns and for rifles, shotguns, and other projectile weapons. It also covers silencer frames or receivers (generally the outer tube or principal housing for baffles or expansion chambers, not a removable end cap) and partially complete, disassembled, or nonfunctional frames or receivers, including certain parts kits that are designed to or may readily be completed to function as a frame or receiver. Raw unmachined billets that have not reached a clearly identifiable unfinished-component stage are carved out, subject to the regulation's examples and the Director's classification factors (templates, jigs, tools, instructions, marketing materials).
NFA "firearm" categories in 27 CFR 479.11 include short-barreled shotguns and rifles (with stated length thresholds), weapons made from shotguns or rifles below stated overall or barrel lengths, "any other weapon," machine guns, mufflers or silencers, and destructive devices. Ecommerce teams should treat NFA items as a distinct compliance and licensing stack, not as ordinary accessories.
For storefront taxonomy, practical tags that track the regulation rather than marketing copy.
clude cartridge cases, primers, bullets, or propellent powder designed for use in any firearm other than an antique firearm (with stated shotgun-shell carve-outs).A firearm muffler or firearm silencer includes any device for silencing, muffling, or diminishing the report of a portable firearm, including combinations of parts designed or redesigned and intended for assemblin
Patterns below are typical public-policy patterns, not underwriting outcomes. Each provider can update lists, apply jurisdiction carve-outs, and still decline a merchant whose disclosed mix looks different from the website copy.
Stripe (restricted, limited availability for legal firearms and other weapons)
Stripe separates prohibited illegal weapons and accessories (plus improperly marked replicas of modern firearms, including toys) from restricted "Legal firearms and other weapons." The restricted bucket, marked limited availability with a sales-team contact note, lists firearms including rifle
PayPal's Acceptable Use Policy prohibits using PayPal for activities that relate to transactions involving ammunition, firearms, or certain firearm parts or accessories, or certain weapons or knives regulated under applicable law. That is broader than "complete guns only." Accessory and regulated-knife SKUs can trigger the same AUP bucket depending on how PayPal interprets "certain" in a given case. Pre-approval charts elsewhere in the AUP do not rewrite that firearms prohibition paragraph.
Square (flat prohibition on firearms, parts, ammo, and weapons)
Square's General Terms of Service restrict sellers from using the Services for the sale of firearms, firearm parts, ammunition, weapons, or other devices designed to cause physical harm. That wording is categorical for Square rails. Treat Square as a non-starter for firearms, firearm parts, and ammunition catalogs unless Square itself provides a current written exception (do not invent one from secondary blogs).
Shopify Payments eligibility guidance states that businesses and products that require regulatory approval or compliance, including firearms, holsters, ammunition, or weapons, are not eligible. Separately, Shop channel prohibited product types include weapons, ammunition, explosives, or related accessories and combat equipment. Shopify's Acceptable Use Policy emphasizes that merchants must follow platform, partner, and payment-supply-chain rules, and that Shop has its own eligibility criteria. A Shopify storefront can still exist while Shopify Payments and Shop remain unavailable for those SKUs. That

ATF rules answer whether an item is a firearm, ammunition, frame or receiver, or NFA firearm under federal firearms law. Processor and platform contracts answer whether that item may ride that company's payment rails. A lawful FFL retail sale can still violate PayPal, Square, Braintree, or Shopify Payments rules. A camping backpack that is not a firearm under ATF definitions can still sit next to restricted SKUs that poison a mainstream MID if the catalog is disclosed poorly.
Operators who collapse those maps into one "tactical equals high risk" slogan underwrite themselves incorrectly. Operators who assume "accessories are fine on Stripe" without reading Stripe's restricted-weapons language do the same. Build catalog risk tags against both maps before choosing a gateway.

By E-commerce 4 Internet Marketers Editorial
Explainer. Website owners and developers who sell "tactical" and outdoor catalogs often mix regulated firearms, ammunition, accessories, knives, and camping gear in one storefront. Mainstream payment platforms publish prohibited or restricted business lists that treat much of that mix as off-limits or revi
Processor patterns are limited to Stripe's Prohibited and Restricted Businesses (last updated 2026-05-13), PayPal's Acceptable Use Policy, Square's General Terms of Service, Braintree's Acceptable Use Policy, Shopify Payments eligibility, and Shop channel prohibited products. This is not le
ATF rules answer whether an item is a firearm, ammunition, frame or receiver, or NFA firearm under federal firearms law. Processor and platform contracts answer whether that item may ride that company's payment rails. A lawful FFL retail sale can still violate PayPal, Square, Braintree, or Shopify Payments rules. A camping backpack that is not a firearm under ATF definitions can still sit next to restricted SKUs that poison a mainstream MID if the catalog is disclosed poorly.
Operators who collapse those maps into one "tactical equals high risk" slogan underwrite themselves incorrectly. Operators who assume "accessories are fine on Stripe" without reading Stripe's restricted-weapons language do the same. Build catalog risk tags against both maps before choosing a gateway.
What ATF definitions put in the firearms bucket
gal, licensing, shipping, or underwriting advice.Public lists are not MCC charts, and they do not guarantee approval or denial for any merchant.
Under 27 CFR 478.11, a firearm is any weapon (including a starter gun) that will, is designed to, or may readily be converted to expel a projectile by the action of an explosive; the frame or receiver of any such weapon; any firearm muffler or firearm silencer; or any destructive device. Antique firearms are excluded from that GCA-facing definition as stated in the regulation. The same section defines ammunition to in
27 CFR 478.12 defines frame and receiver in detail for handguns and for rifles, shotguns, and other projectile weapons. It also covers silencer frames or receivers (generally the outer tube or principal housing for baffles or expansion chambers, not a removable end cap) and partially complete, disassembled, or nonfunctional frames or receivers, including certain parts kits that are designed to or may readily be completed to function as a frame or receiver. Raw unmachined billets that have not reached a clearly identifiable unfinished-component stage are carved out, subject to the regulation's examples and the Director's classification factors (templates, jigs, tools, instructions, marketing materials).
NFA "firearm" categories in 27 CFR 479.11 include short-barreled shotguns and rifles (with stated length thresholds), weapons made from shotguns or rifles below stated overall or barrel lengths, "any other weapon," machine guns, mufflers or silencers, and destructive devices. Ecommerce teams should treat NFA items as a distinct compliance and licensing stack, not as ordinary accessories.
For storefront taxonomy, practical tags that track the regulation rather than marketing copy.
clude cartridge cases, primers, bullets, or propellent powder designed for use in any firearm other than an antique firearm (with stated shotgun-shell carve-outs).A firearm muffler or firearm silencer includes any device for silencing, muffling, or diminishing the report of a portable firearm, including combinations of parts designed or redesigned and intended for assemblin
Patterns below are typical public-policy patterns, not underwriting outcomes. Each provider can update lists, apply jurisdiction carve-outs, and still decline a merchant whose disclosed mix looks different from the website copy.
Stripe (restricted, limited availability for legal firearms and other weapons)
Stripe separates prohibited illegal weapons and accessories (plus improperly marked replicas of modern firearms, including toys) from restricted "Legal firearms and other weapons." The restricted bucket, marked limited availability with a sales-team contact note, lists firearms including rifle
PayPal's Acceptable Use Policy prohibits using PayPal for activities that relate to transactions involving ammunition, firearms, or certain firearm parts or accessories, or certain weapons or knives regulated under applicable law. That is broader than "complete guns only." Accessory and regulated-knife SKUs can trigger the same AUP bucket depending on how PayPal interprets "certain" in a given case. Pre-approval charts elsewhere in the AUP do not rewrite that firearms prohibition paragraph.
Square (flat prohibition on firearms, parts, ammo, and weapons)
Square's General Terms of Service restrict sellers from using the Services for the sale of firearms, firearm parts, ammunition, weapons, or other devices designed to cause physical harm. That wording is categorical for Square rails. Treat Square as a non-starter for firearms, firearm parts, and ammunition catalogs unless Square itself provides a current written exception (do not invent one from secondary blogs).
Shopify Payments eligibility guidance states that businesses and products that require regulatory approval or compliance, including firearms, holsters, ammunition, or weapons, are not eligible. Separately, Shop channel prohibited product types include weapons, ammunition, explosives, or related accessories and combat equipment. Shopify's Acceptable Use Policy emphasizes that merchants must follow platform, partner, and payment-supply-chain rules, and that Shop has its own eligibility criteria. A Shopify storefront can still exist while Shopify Payments and Shop remain unavailable for those SKUs. That
