Great minimalistic upgrade. - POF USA Universal Bolt Catch Black Anodized 00667P

Put this on my 5.56 rifle build. Very nice feel to it, and does what it's supposed to do. These should be the standard bolt catch on every AR15 pattern rifle. My only complaint is that the side of the catch opposite the button is unfinished, and has bandsaw marks. Mine had a burr along that corner that caused it to bind a bit in my receiver, so i had to do some filing on it to make it function smoothly without binding up. I modify practically everything, so im not taking stars off for that, but they could have at least machined that surface and deburred the edges. That being said, you should always expect to have to make modifications to anything that comes with the word "universal" on it. Would recommend and buy again. Plan to get another one for my .300blk pistol.
