Building an AR-15 from a stripped lower receiver? The CMMG AR-15 Complete Lower Parts Kit gives you all the internal components needed to finish the fire control group and trigger assembly without hunting down a dozen individual parts. This is your one-stop solution for getting a bare lower to functional status—no compatibility guessing, no missing springs at the bench.
CMMG's LPK includes everything from the A2 pistol grip and safety selector to the trigger, hammer, disconnector, and all associated springs, pins, and detents. Whether you're assembling your first AR or building your tenth, having all these pieces together saves frustration and keeps your build on track. The kit is designed for AR-15 platform rifles and covers both the fire control group and the small mechanical parts that make the lower receiver work.
This complete lower parts kit is ideal for home gunsmiths, competitive shooters, and hunters who prefer to assemble their own firearms. It's the kind of practical, no-frills component kit that serious builders rely on when they want quality parts without unnecessary markup. Everything you need is in the box.

Yes, this LPK is designed for AR-15 platform rifles. It contains all the small parts and fire control components needed to complete a stripped AR-15 lower receiver.
