Review by Gunplay101
I purchased 10 of these so my Sig 716P magazines would comply with the California 10 round magazine capacity limit. These blocks do the job but they have one drawback, they fit the Pmags so precisely that you can barely get 10 rounds in the magazines with no extra room at all, I mean zero, there is no room left to compress the stack enough to get the magazine seated on a closed bolt. That's not a problem unless you are in the s**t and need to make a mag change before the last shot is fired and the bolt is closed. I had to put the blocks in my vertical mill and remove .100" from the top of the block and the notch at the top of the block in order to make them work correctly so unless you are OK with only loading 9 rounds in your block limited magazines you will have to plan on doing some work to the blocks them selves before installation.
