CMMG’s 10mm BANSHEE is the first AR capable of reliably running the wide assortment of 10mm ammunition on the market. It uses CMMG’s patent pending Radial Delayed Blowback operating system to significantly reduce felt recoil. The 10mm BANSHEE ships with one 30-round SGM Magazine (Glock Magazine Compatible) and uses CMMG’s patented bolt catch linkage to hold the bolt open after the last round.

The 10mm BANSHEE is available in Short Barreled Rifle (SBR) and AR pistol configurations. With a variety of different options and furniture to choose from, the BANSHEE 100, BANSHEE 200 and BANSHEE 300 series will have the right combination for you when concealment and portability matter the most.

Each 10mm BANSHEE comes with an H3 buffer and a 3.5oz tuning weight pre-installed in the carrier. A standard carbine buffer is also included in the box – ideal for those running lighter loads.
