Boonville, Missouri–based CMMG Inc. has released and is shipping its 10mm Banshee semi-auto pistols and short-barrel rifles with its radial delayed blowback operating system and last-round bolt hold open feature.
CMMG’s patent-pending radial delayed blowback operating system incorporates a mechanical delay that forces the bolt to rotate, momentarily slowing the bolt carrier group, which allows chamber pressures to fall before cycling.
This mechanical delay allows for reliable function with a variety of ammunition and removes the need for a heavy bolt, buffer and spring typically required in direct blowback systems.
The manufacturer claims the radial delayed blowback design cuts felt recoil, produces cleaner function, and reduces bolt velocity, allowing for faster follow-up shots.
“From the moment we first introduced the Radial Delayed Blowback operating system back in 2017, our customers have repeatedly requested that we use this innovative system to chamber 10mm,” said Chris Reinkemeyer, CEO/CFO at CMMG. Not only do our 10mm offerings work with the wide range of ammunition available today, they also tame the felt recoil by a significant margin.”
CMMG developed a unique bolt catch linkage system (U.S. Pat. No. 9952011) to allow the last-round bolt hold open feature to be compatible with the 10mm and other pistol cartridges. This feature provides familiarity for AR users while changing magazines for faster reloads.
The 10mm will be offered with an 8-inch barrel, starting at 5 pounds 9 ounces (unloaded) and an overall length of 24.3 inches. One 30-round factory SGM TACTICAL 10mm magazine (GLOCK®compatible) ships with the firearm where allowed. To maximize performance and reduce recoil for the varying power levels of 10mm ammunition, the BANSHEE 10mm (Mk10) ships with an H3 buffer pre-installed and an additional standard carbine in the box.
