This Sionics Weapon Systems Complete AR-15 Lower Receiver comes fully assembled without a stock, so you can choose your favorite or add a brace for a pistol build. The receiver itself is forged from 7075-T6 aluminum and hardcoat anodized black. The upgraded features that come with this package are an end plate with a QD sling swivel slot and an H buffer. Additionally, the 6 position buffer tube has a dry film lubricant applied to reduce friction between it and the buffer. The Magpul K2 pistol grip and enlarged polymer trigger guard make this lower receiver group that much better.
