Description

This ultra-compact AR-15 upper’s the perfect way to affordably build a quality AR pistol. Featuring a shorty 8.5” barrel made from mil-spec 4150V with 1:7 twist rate, this unit’s guaranteed to provide precision with any 5.56 loads. The barrel ships with a nitride finish. Nitride greatly increases barrel life while affording greater accuracy than chrome-lining.

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.
