This is the Colt M16A1 Retro Re-issue lower receiver, built by Colt to replicate the original Vietnam-era M16A1 down to the last detail. If you’re chasing a clone-correct M16A1 build, this is the foundation piece you want — forged 7075-T6 aluminum, gray anodized finish, partial fence around the magazine release, and the unmistakable “PROPERTY OF U.S. GOVT” and Colt rollmarks on the magwell.
This is a complete semi-auto lower receiver shipped with the authentic A1 fixed stock assembly, A1 pistol grip, A1 receiver extension (rifle-length buffer tube), rifle buffer and spring, and mil-spec lower parts kit. The trigger group is semi-auto only to stay ATF-compliant, but every visible component matches the original M16A1 profile — no shortcuts, no modern giveaways.
Pair this lower with an A1 20″ upper and a triangle handguard and you’ve got a rifle that would pass muster at any SOG reunion. Colt retro lowers are produced in limited runs and disappear fast. When they’re gone, they’re gone.
Order yours today and build the M16A1 clone you’ve always wanted — before the next Colt production run sells out.
