AAT 5.56 Forged Lower Receiver what makes us a little different we have eliminated the hassle of beating the roll pin in the hard to get to bolt catch and replaced it with a set screw. Also the rear takedown has set screw and a nylon tension screw to keep your upper and lower from that wobble, not that you will nee it because our sets fit tight but with time and wear if it starts to get a little wobbly, PROBLEM SOLVED!
