Amend2 polymer 6.5 grendel mags

[A5BLASTER]

The prototype I saw a few months ago was not single stack. Was still double stack, but single, center feed, like a pistol magazine. They may have changed it by now though. I have not been by the office in a few months.

Single feed you say hmmmmmm, i smell a home brewed windowed polymer mag in the works when I get my hands on one.

Tryed it with the pmags but they got too limp when windowed out for loading 5 rounds long and would flex and not load properly.
