Mag block for CZ 452, 455, 457. These fit snuggly into the mag well and allow others to see that there isn't a mag installed and that the bolt is back. If you would like a style or color that is not listed let me know and I will see what I can do, thanks! These do NOT prevent a round from being in the chamber so they do not offer any additional safety.
