Brownells 75th Anniversary - A Shooting Heritage

The Iconic Rifle

The Brownells BRN-16A1® Rifle replicates the iconic M16A1 rifle issued to thousands of US Soldiers, Marines, Sailors & Airmen.

The M16A1 was finalized for adoption in 1967 as an improvement from the XM16E1. The M16A1 represents the iconic rifle of the Vietnam War and the US Military from the 1960s through the 1980s. The A1 featured improvements to reliability, including a chrome bore and chamber and was issued with proper ammunition. The A1 also saw the adoption of the full “magazine fence” protecting the magazine release from unintended activation. The classic A1 flash hider also makes for an extremely effective device, and won’t bend or catch foliage.

Recruits familiarize themselves with M16A1 rifles during basic training
