Product Description

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 patented 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. 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. For those planning to run the 10mm BANSHEE suppressed, check out CMMG's 8oz buffer (sold separately) for additional tuning.
