An Experimental Carbine

The Brownells Model BRN-605® Rifle replicates the look of the experimental-only, never-issued Colt 605, the first attempt at making an AR-style carbine.

The Model 601 was the very first AR-15 adopted by the US Military, seeing service with the United States Air Force & other units in Southeast Asia early in the 1960s. Featuring classic green furniture and slick side receivers, the 601 is one of the sleekest models ever developed, and represents almost a true iteration of Eugene Stoner’s original design philosophy.

Progression of the 605.
