Overview
Built for retro carbine projects, this Brownells reproduction is aimed at shooters restoring the look and layout of classic XM177-pattern rifles. It matches the original device’s exterior dimensions, flash hider cuts, and grenade ring, making it a fitting choice for period-correct builds rather than modernized setups. The unit fits 1/2-28 threads and is finished in black oxide, with dimensions listed at 4.335 inches overall and 4.45 inches with the grenade ring. It is specifically identified for XM177, XM177E1, XM177E2, and related Colt Model 609, 610, 619, and 620 reproduction builds.
