Will this mount to a standard AR-15 pistol lower? I have a current 5.56 pistol lower, and would be nice to be able to swap uppers w/out building a new lower.
John C on Jan 11, 2019
BEST ANSWER: Yes but you will also need a mag conversion block for Colt or Glock mags. Or MEAN Arms Endo mags which are pretty cool. Converts Pmags to 9mm with integrated ejector, and lrbho works too.

Oscar Alexandre on Jan 22, 2019
BEST ANSWER: Will work with any AR15 Pistol lower with a magazine block adapter, or put it on one of the dedicated Glock or Colt Pistol lowers. Just don't put it on a rifle lower without a tax stamp.
