Description

Get superior performance in a compact configuration with this shorty 8.5” 5.56mm NATO AR-15 upper. Boasting a heavy barrel made from 4150V (mil-spec) steel, the only thing standing between you and MOA shot groups is a pull of the trigger. A pistol gas system ensures you can shoot light or heavy loads without modification.  A free-float 7” M-Lok handguard keeps things balanced and nimble, while offering plenty of space for irons and accessories. Out back, a forged 7075 T6 receiver gets the mil-spec stamp of approval. Inside, M4 feed ramps, an M16 BCG, and pistol gas system keep everything running smooth. Backed by Lifetime Warranty.
