80% AR15 Lower Receiver With Trigger Guard

80% AR15 Lower receivers are machined to mil-spec tolerances which make them perfect for the DIY Gunsmith. The Mag well is fully broached on all our AR-15 80% lowers for a perfect fit every time.

The operations left to be completed are as follows:

    fire control group
    trigger pin
    hammer pin
    trigger slot
    safety selector hole.

This is a not an FFL item. This is not a complete receiver, this is an 80% receiver and still requires machining to be completed.
