It doesn't sit very clean, but it functions well.
This is in a Manners inletted for Rem BDL.
First one is the flush and the second it what I think comes with the Gen 2. Both hold 3 rounds.
I am thinking when I re-barrel, it will be a 300 WM as it allows me to run them at the length I have them seated in my other 300 WM. These mags are for the RUM size.
