Good Sunday to all. Attempting to change my first hand guard ever and bought the ProMag PM123A. Went to put my upper in the block and it doesn't fit?! Any experienced help would be awesome. What system do you use for putting your upper in the vise? Best regards.

What block are you using?
I use a vise block I got from Brownells
It is the second one listed on this link: AR-15 Upper Receiver Block | Brownells
