A true industry first is the CMMG FourSix, an AR-style PDW platform chambered for the 4.6x30 mm HK cartridge, the first such offering on the U.S. commercial market.

Based on CMMG’s Mk4 AR platform, the FourSix uses the same AR-style controls and modularity popular with today’s shooters. This also enables AR owners to mount FourSix upper receivers onto their mil-standard AR-15 lowers, thanks to the compatible design of CMMG’s 40-round FourSix magazine.

At launch, two models are available in the FourSix lineup, both 300 Series Banshee models equipped with 8" barrels. One is configured as an AR-style pistol, while the other is an NFA-regulated short-barreled rifle. MSRP for CMMG's FourSix will run about $1,400. For more information, please visit cmmg.com.
