USSurplus Bare Bone Mil-Spec AR15 Lower Build Kit
Great kit for complete build to a stripped lower everything less the stock. Even had QD end plate to the buffer tube. Highly recommend. Hard to beat this quality at this price point.
USBasic mil-spec parts kit.
Good parts, assembly like any other brand. Trigger is heavy and breaks cleanly and not mushy. All of the contact points were polished from the factory (unlike other brands I’ve purchased). Would buy again.
