Frequently Asked Questions

What is CMMG's radial delayed blowback operating system?

CMMG's radial delayed blowback system is an innovative operating system designed to manage recoil and pressure more effectively than traditional blowback systems. It uses a rotating bolt and a specially designed bolt carrier to delay the opening of the action, resulting in a smoother shooting experience and less felt recoil, particularly beneficial for powerful pistol cartridges like 10mm Auto.

Can I use my existing AR-15 lower receiver with CMMG's 5.7x28mm Banshee upper?

What are the advantages of CMMG's radial delayed blowback system for 10mm Auto?

For the 10mm Auto cartridge, CMMG's radial delayed blowback system offers significant advantages. It effectively manages the higher pressures and wider variance in ammunition loads inherent to 10mm, providing a more controllable and comfortable shooting experience compared to a standard blowback system which can be harsh.

How does CMMG's MK10 handle magazine compatibility?
