First of all there are 2 defects, one marking from installing the bolt release and a roll pin that jammed with the trigger guard. It’s the roll pin than can be extracted but I left it because I didn’t plan on changing the trigger guard. Now, that being said this is an Anderson lower with a PSA LPK, CMC 3.5lbs trigger, and a Spikes T2 buffer and spring, PSA castle nut/end plate/carbine extension. If you’re running mid length 5.56 or a short barrel the T2 buffer should work well for you. If not I could switch it to a carbine buffer and take $10 off. This lower can be used for pistol or rifle as it was a stripped lower. Was test fired with a 8.5” 300BLK and a 16” mid-length 5.56 without issues. Just looking to free up cash for other builds. Must have GA carry permit
