Precision-crafted to unlock the full potential of 22 ARC.
The 18″ 22 ARC M-LOK Upper Assembly is built for shooters seeking cutting-edge small-caliber performance in a precision AR-15 package. It features a premium stainless steel medium-contour barrel, optimized for the high-efficiency burn rate of 22 ARC. The mid-length gas system ensures smooth cycling, reduced port pressure, and enhanced accuracy. A nitrided steel gas block, American-made M-LOK handguard (style may vary), and forged upper round out this complete package. Assembled with Permatex 242 and AEROSHELL 33MS for long-term reliability. BCG and charging handle not included.
Why 22 ARC?
