Upper receiver block - AIM Sports Inc AR Upper Receiver Vise Block

I'll start off with it got the job done that I needed. With that being said, some things that were not convenient. When you're placing the upper in the block it's a bit like horrible tetris to figure out which way and what spot to settle it in. No big deal, once it's in the vice block it doesnt close flush, the part where the receiver is closes fine, but then the other side is not flush pressed together, maybe some sort of molding issue. The material it's made from is sturdy and did just fine in the vice block (not cheap made)
