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. The Banshee 300 pistol is outfitted with a CMMG RipBrace with 6 Position Enhanced Receiver Extension and Ambi Sling Plate.

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. A CMMG 8oz buffer (sold separately) is also available for additional tuning.

All BANSHEE 300 series firearms are the shortest configuration that we make in their respective caliber.
