Ambidextrous AR-15 UIC Stripped Lower Ambi Receiver 5.56mm

There are tons of stripped lower receivers on the market, but only one is loaded with the special features found in the American Defense ADM UIC Lower Receiver. This definitely isn't your standard, mil-spec, budget-priced lower, as the ADM team incorporated a number of next-generation features into this design. To start, each American Defense ADM UIC Lower Receiver is machined with radii and chamfer cuts that make this firearm a marvel of modern machining. The receiver features a 20-degree magwell cut that speeds up reloads, and the well also features reinforcing ribs that make it 40 percent stronger than standard, mil-spec lowers with only half an ounce of added weight.
