Description:

These 80% Lower receivers for AR 15 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.

80% AR 15 Lower receivers are machined from 7075-T6 forgings

The operations left to be completed on the 80 percent lower receivers 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 AR-15 Lower receiver and still requires machining to be completed.
