Get MBX
Thought I’d give these a try and save a little over the MBX. Looks like you need a Grams follower to get 20 rds, I could only load 18 with the supplied follower. The tube material appears to be a little thinner than a MBX and the formed bends are less crisp than an STI. I have Atlas parts on a couple of my guns and am a fan but this mag was a let down. I assume it will run but out of the box I can’t say it’s good to go.
