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. Regardless if this is your 1st or 20th AR build, you can order your lower parts kits with confidence from knowing that we guarantee our products, they are made in the USA and if you need anything, we are available to help you 24/7.
