Re: Why PMAG for DPMS but not AR10
Because the SR25 is the platform the US military adopted. Additionally, there are more commercial manufacturers of the SR25 pattern: DPMS, LMT, KAC, Larue. The AR10 is made primarily by Armalite and Noveske. So for both military and commercial "bang for the buck" in terms of R&D and tooling dollars spent, it makes good sense to make a SR25 mag.
