The Colt M4A1 Carbine SOCOM Reproduction Rifle is a semi-automatic, direct gas impingement rifle chambered in 5.56mm NATO, meticulously engineered to serve as a faithful, non-NFA civilian reproduction of the iconic United States military battle rifle. This highly collectible firearm incorporates a true 14.5-inch chrome-lined, button-rifled SOCOM heavy profile barrel featuring a 1:7" right-hand twist rate and iconic M203 grenade launcher mounting flats, brought to a legally compliant 16.1-inch overall barrel length via a permanently pinned and welded extended A2 flash hider. It is built on mil-spec forged 7075-T6 aluminum upper and lower receivers finished in a matte black Type III hardcoat anodizing, historically enhanced with milestone-correct "PROPERTY OF THE U. S. GOVT. M4A1 CARBINE" lower receiver rollmarks. The battle-tested layout comes factory-outfitted with a genuine military-contract Knights Armament Company (KAC) RAS quad-rail handguard with polymer rail covers, a side sling swivel at the gas block, an ambidextrous safety selector switch, an H2 buffer, and an M16-type bolt carrier group. The classic combat configuration is rounded out by a standard single-stage trigger, a traditional polymer A2 pistol grip, a 4-position collapsible M4-style buttstock, a fixed A2 front sight tower, and a premium folding MaTech military target rear iron sight. Weighing 6.95 pounds unloaded, the rifle feeds from an included 30-round magazine.
