Zanelli –
Milled very nicely. Like the fact that it has screws for both the bolt catch and that nasty rear detent spring. However, I have noticed on 2 recievers that the rear detent hole is finicky as far as what detent it’ll allow to drop in (which resulted in one getting scrapped). I have tried multiple different detents before finding one that worked. Also, don’t forget to snip about 1/4 off the spring if you use the screw.

It’s a good, solid 80%. Chose it because it’s threaded for the bolt catch and rear takedown. Milled very smooth. Problems occurred when it came to assembly, though. Rear takedown pin hole was undersized, and the pin became lodged too tight to provide secure lockup. Next one I’ll be more aware of that issue before making a $90 paperweight.

Fast shipping, quality lower, I had a aftermarket ambi mag release that wouldn’t work on any other lower, but for whatever reason it worked on this one. Made me pleased I didn’t have to waste a good ambi mag release.
