"RCMP guy" is reading your comment and just spit his coffee all over his monitor. "holy hell boys, I just realized that LAR mags can be used in AR-15s!!!" Add it to the ban list!
Also the LAR-15 mags have "LAR-15" on the side and were manufactured for the AR pistol. If anyone even breathes the words "designed for the AR-15" when talking about the LAR, this little area of technicality will evaporate and we will lose the LAR.
