Honestly couldn’t tell you. I bought them from another hide member a few months ago but haven’t used them as I’ve been waiting for parts to come in for a build. They are in great condition. I can add more pictures if requested.
I just had my RWSnyder 300wm with the PTG DBM and these same mags out yesterday. Not the first feed issue in the 220rds that have been thru the rifle.
Bump for great mags.
