Lower Parts Kit

A Lower Parts Kit is a vital component of any AR build. The lower parts kit includes the hammer, stainless trigger, magazine catch, takedown pins, detent springs and other vital accessories for your lower receiver. A lower parts kit is absolutely necessary to convert your 80% lower receiver from a piece of aluminum to a fully-functioning firearm quickly and cost-effectively.

All of the components in these parts kits come in individually labeled bags for quick recognition and easy installation. We guarantee 100% Milspec fit and tolerances so you are not forced into buying a brand-specific, proprietary lower receiver.
