Mag selection

I love my 300 Blackout. I have found my favorite subsonic ammo. There is one thing I worry about, now that I have had this rig for a while. Feeding it the wrong ammo.

Now to make sure I load the 300BO ammo in only metal mags. It's not that the metal mags function better, look better or feed better.

They look and feel different.

Even in the dark I can tell the difference.

--I love this can. I want them on everything now.
