Unlike the existing pistols, the 5.56 NATO version will have a 12.5″ barrel. The 9mm and 300 BLK guns use an 8.2″ barrel. This pistol uses a free-floating KeyMod hand guard. KeyMod hand guards are thinner than traditional quad-rail designs. Compatible accessories can be attached directly to the hand guard. Also, short lengths of rail can be added for non-compatible kit.
An ambidextrous, single-point sling attachment is standard, as is the Magpul MOE pistol grip and 30-round magazine.

I’ve previously had the chance to shoot and review the Mk4 AR pistol in 300 BLK. That gun ran well and was accurate.
