The LBE Unlimited AR-15 lower parts kit (brand part no. AR15LPK) supplies the small parts needed to complete a stripped AR-15 lower receiver, apart from the pistol grip and trigger guard. It covers the fire control group, the bolt catch, the magazine catch and the takedown and pivot pin hardware in one made-in-USA kit. That makes it a straightforward choice for a new lower build or for restocking replacement parts, and builders who already have a favorite grip and trigger guard can pair it with those.
