Last week, CMMG released a new Banshee in 10mm. I am a big fan of the 10mm round. Naturally, I was excited about CMMG 10mm Banshee. 

The CMMG 10mm Banshee was designed from the ground up reliably run a wide range of 10mm ammunition. The Banshee is running a Radial Delay Blowback System which allows for less felt recoil. Which helps keep shooters on target and allow for quicker follow up shots. The 10mm Banshee ships with one 30-round SGM magazine and uses CMMG bolt catch linkage that hold open after the last round.

Below is CMMG’s description of their 10mm Banshee and Specs for the rifle. 

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

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