The 2 issues we've seen:
1) The front pivot pin retaining spring needs to be trimmed about 1/3 of an inch as the hole is not deep enough in the original design. Not a biggy.
2) The bolt catch retaining screw cannot be tightened all the way or it binds the bolt catch. Adjust it out till the bolt catch moves freely and leave it. It won't back out.

Lots with this issue above. Seems some charging handles work and some don’t. They pull the bolt back 1/4” less then an ar does. As the receiver is different lengh then an ar. Nothing to do with mags. The bolt catch can not engauge as the bolt is still in way and not pulled rearward enough.
My friend is very happy with his build.
