16″ 5.56 AR-15 Rifle Build Kit W/12″ Quad Handguard
The 16″ 5.56 AR-15 Rifle Build Kit W/12″ Quad Handguard combines the major components needed to complete a standard AR-15 rifle build around a compatible lower receiver. It pairs a complete 16-inch 5.56 NATO upper with a 12-inch free-float quad rail, a full lower parts kit, plus a stock and carbine buffer tube assembly for a practical, ready-to-build package.
The upper features a 16-inch SOCOM-profile 5.56 NATO barrel with a 1:7 twist and a mid-length gas system. It includes a black nitride bolt carrier group and standard charging handle, plus an APOC Armory nitrided steel gas block and A2 birdcage muzzle device. The 12-inch free-float quad rail provides continuous accessory mounting space and keeps the handguard from contacting the barrel.
