Requirements for Sale of Firearms Ammunition

Plain-English Summary

AI-generated

House Bill 25-1133, which has been signed into law in Colorado, requires that retailers sell ammunition only with the help of a store employee and prohibits selling it to anyone under 21 years old. However, there are exceptions for people aged 18 to 20 who have certain certifications or protections, such as military service members, veterans, hunters, and those born before January 28, 2007. The law also mandates that delivery services verify the recipient is at least 21 years old when shipping ammunition. This bill affects anyone buying or selling ammunition in Colorado and aims to enhance safety measures around ammunition sales.

Official Summary

The act requires that ammunition sold at retail must be accessible to a purchaser or transferee only with the assistance of the vendor, and the act prohibits the retail sale of ammunition to a person who is younger than 21 years of age. The act includes exceptions for in-person sales to persons who are 18-20 years of age at shooting ranges, who are members of the military and veterans, who have a hunter education certification, who are protected by a protection order, or who were born on or before January 28, 2007; sales to on-duty peace officers; and sales of rimfire ammunition. Unlawful sale of ammunition by violating either requirement is a civil infraction; except that a second or subsequent violation is a class 1 misdemeanor. The act requires a retail ammunition vendor who is shipping ammunition to use a delivery service that verifies that the person receiving the ammunition is 21 years of age. The act requires a retail ammunition deliverer to comply with federal law regarding the labeling and packaging of ammunition. When delivering a package containing ammunition sold at retail, the act requires a retail ammunition deliverer to verify that the person receiving the delivery is 21 years of age or older and obtain written acknowledgment of receipt from the recipient. Notwithstanding the age verification requirement, a retail ammunition deliverer may verify and deliver ammunition to a person who was born on or before January 28, 2007. The age verification and written notification requirements do not apply to a retail ammunition deliverer who does not know that the package contains ammunition because the sender failed to notify the deliverer that the package contains ammunition. (Note: This summary applies to this bill as enacted.)
