Designed for steady, repeatable performance in varied environments, the Sons Of Liberty Gun Works AR-15 LOWER RECEIVER SEMI-COMPLETE REBELLIOUS STRIPES BLK emphasizes functional reliability and straightforward operation. Sons Of Liberty Gun Works imbues their lower with the same spirit of resistance with their Rebellious Stripes lowers. These beautifully forged receivers are made from mil-spec 7075-T6 right here in the USA. The contour is fully machined to remove any flash marks from the forging. The result is an exacting fitment that assures precise tolerances. Finally, each receiver is given a hard-coat black anodization, preventing scuffs and corrosion. Ideal for range training and recreational shooting, this lower receiver comes partially assembled with an A5 buffer system, A5H2 buffer weight, Sprinco green spring, QD end plate, and B5 Systems pistol grip. Sons Of Liberty Gun Works is renowned for their commitment to quality and innovation in firearm manufacturing.
