Quick Answer: Colorado Ammo Laws (2026)
The questions buyers ask most — reviewed June 9, 2026.
// THE PROCESS
How Colorado Ammunition Purchases Work
Confirm You Meet the Federal Age Rule
You must be 18+ for rifle and shotgun ammunition and 21+ for handgun ammunition. Colorado adds no stricter state age requirement, and retailers verify your date of birth at checkout.
Order From Any Licensed Retailer
There is no state permit, ammunition card, or eligibility check to upload. Pick your caliber and quantity and check out with your Colorado shipping address — the same as ordering any other product online.
Ships Direct to Your Door
Ammunition is a hazardous material, so it ships by ground (UPS/FedEx) with adult-signature confirmation and a flat HAZMAT fee. No FFL transfer and no in-person pickup are required in Colorado.
Check Local Ordinances
State law is federal-standard, but a city or county can have its own rule. Confirm any local requirements before a large order, and treat anything you can't verify as “verify current status.”
// LEGAL STATUS UPDATE
CURRENT LEGAL STATUS: Colorado follows federal ammunition rules, with a state magazine-capacity limit (15 RDS). Ammunition itself can be ordered online and shipped home. Reviewed June 9, 2026.
Not legal advice. Ammunition law changes frequently and can vary by city or county. The details below were reviewed in June 2026 — always confirm current requirements with your state Attorney General, State Police, or a licensed attorney before you place an order. Items we could not independently confirm are marked “verify current status.”
Federal Rules That Apply in Colorado
Colorado does not layer state-specific ammunition-purchase requirements on top of federal law, so the federal floor set by the Gun Control Act of 1968 is the whole picture. Four rules matter:
- Age. You must be at least 18 to buy rifle and shotgun ammunition and 21 to buy handgun ammunition from a licensed dealer. Retailers verify your date of birth at checkout.
- Prohibited persons. Federal law bars ammunition sales to convicted felons, fugitives, unlawful drug users, people adjudicated mentally defective, illegal aliens, dishonorable dischargees, and anyone subject to a qualifying restraining order, among others.
- No Form 4473 for ammo. The 4473 and NICS background check apply to firearms, not to standalone ammunition purchases. There is no federal background check just to buy ammunition.
- Armor-piercing ban. Armor-piercing handgun ammunition (18 U.S.C. §921(a)(17)) is prohibited for civilian sale nationwide.
Buying Ammunition Online in Colorado
Yes — Colorado residents can order ammunition online and have it delivered to a home address. Because the state imposes no ammunition permit, eligibility check, or ship-to-dealer requirement, the process works like ordering any other product: choose your caliber and quantity, check out with your Colorado shipping address, and the retailer ships once it confirms you meet the federal age requirement. There is no state paperwork to upload and no in-person pickup step.
Shipping Ammunition to Colorado
Ammunition ships directly to Colorado addresses from licensed US retailers. The only constraints are the universal federal and carrier ones: ammunition is a hazardous material (ORM-D / Class 1.4S), so it travels by ground only — never air — usually via UPS or FedEx with adult-signature confirmation. Most retailers add a flat HAZMAT fee (about $25–$40) that free-shipping thresholds typically exclude. Colorado adds no state-level shipping restriction.
Prohibited Ammunition Types
Colorado does not maintain a state list of banned ammunition types. The only categorical restriction is the federal prohibition on armor-piercing handgun ammunition. Standard centerfire and rimfire ammunition, hollow points, and standard-capacity magazines are all legal under Colorado law.
State-Specific Notes
Colorado's one meaningful departure from the federal standard is its 15-round magazine limit, in force since July 1, 2013. It is unlawful to manufacture, sell, transfer, or possess a magazine capable of accepting more than 15 rounds, unless it was owned before that date and kept in continuous possession. This is a magazine rule, not an ammunition rule — buying ammunition online and shipping it to your Colorado home is fully allowed.
Check for local ordinances in your city or county before ordering, and treat anything you cannot independently confirm as “verify current status.”
Recent Changes (2025–2026)
The 15-round magazine cap (in force since July 1, 2013) was unchanged in 2025–2026, but enforcement tightened. Effective August 1, 2026, Colorado FFLs must ensure that any reduced-capacity magazine they sell is permanently incapable of accepting more than 15 rounds — temporary blocks or removable limiters no longer satisfy the law. Colorado also enacted broader firearm-sale legislation in 2025 affecting certain semi-automatic firearms; if you are buying a regulated firearm rather than ammunition, verify current status.
Penalties for Violations
Because Colorado defers to federal law on ammunition, a lawful buyer's exposure is essentially nil. The real risk is federal: selling ammunition to a prohibited person, or buying or possessing ammunition while prohibited, is a federal felony. Confirm the exact grade for any specific situation with counsel.
