I was excited about using this lower for a URGI build due to its simple/clean rollmark. Unfortunately the bolt catch pin hole was oversized/out of spec.

The second one spec'd out ok but the finish left a little bit to be desired. I expected better for the price. Will go with SOLGW on the next one--everything I've ordered from them has been flawless.
