DPMS mags don't work? Strange as they were designed to be compatible with original AR10 waffle mags.
Still early but I'd be interested to know if any original style mags work. That is AR-10 waffle mags, KAC SR25 mags, Brownells 308 AR mags etc...
It's supposed to based on an AR102 and now it sounds like an actual AR102 mag won't work or is this strictly the DPMS version?
I think it is the DPMS version only, but time will tell. Apparently the way the mag is manufactured, the sheet metal wraps around itself at the front of the mag creating a double thick wall. This double thickness prevents the mag from seating into the magwell. This is based off of info from Ryan at SFRC. I had bought those mags for this rifle and had to return them after learning this.
The ASC 5/20 mags should work from what I can tell. They don't seem to have that "double wrap" at the front of the mag. I am considering ordering one to test it.
