UPPER GROUP, BANSHEE, FIXED EJECTOR - COYOTE TAN, 9MM, 5"

Upper Group, BANSHEE

RDB was an advancement from straight blowback. Compact action RDB was an advancement to the original RDB. This (fixed ejector on RDB) is a continued advancement bringing new technologies to the original platform.

If you’re looking to build the most compact 9mm AR then look no further. CMMG®’s 9mm RDB uppers feature uncompromised design and engineering with styling that is never mistaken for something else. Having more options is always better, like what magazines you would like to use. 9mm Radial Delayed Blowback uppers are designed exclusively to work with CMMG MkGs, Mk17, and Mk9 9mm lowers, or with mil-spec AR15 lowers using our 9mm Conversion Magazines. Available in different Cerakote finishes, all CMMG® Upper Groups come complete with bolt carrier group and ZEROED™ accessories including:

• ZEROED AR15 Polymer Dust Cover

Radial Delayed Blowback™ Operating System

Originally developed for the .45 ACP MkG platform, CMMG has adapted our Radial Delayed Blowback system across our pistol caliber lineup to create pistols and rifles with a softer recoil impulse and reduced bolt weight compared to traditional straight blowback systems.
