This review covers the Brownells XBRN177E2 retro rifle, a faithful reproduction of the original 1967-era carbine. The reviewer highlights its light weight (under 6 lbs), true-to-type features like the XM177 moderator (pinned and welded to meet 16-inch barrel requirements), and M16A1 receivers. It was used successfully in the Desert Brutality competition's retro division. Accuracy testing revealed a preference for lighter bullets (40-55 grain) with the 1:12 twist rate, struggling with heavier 69-77 grain rounds.
