Really wanted to like this lower.
by Jacob -
This lower is way out of spec! The bolt catch slot is too wide, leaving it really sloppy. Also the detent hole for the catch is too deep, so I had to stretch the spring just to make it functional. It comes with a nice Allen screw for the catch pivot pin, too bad it's too small of dia and only stops when the threads hit the catch. Then it acts like a jam nut, so the catch won't pivot. Had to cut a roll pin in half and put it down the hole so the Allen screw would bottom out on that. Had to file and grind out the rear so I could get the upper to pin in the back. Tried 3 different uppers and none would fit. Felt like I bought a 80% lower! Holes for take down pin detents are too big and cause the spring to not stay in line making it really hard if not impossible to unpin the upper. Spent way too much money on this to have this many issues.
