Brighton Gun manufactured right here in Wisconsin.  

Do you want micro Uzi or M11a1 speed from your M11/NINE?  Then look no further.  These drop in “cubes” slide around the recoil rod and ejector assemblies and sit between the rear of the bolt and your receiver.  These will yield roughly 1,700 RPM ROF out of your M11/NINE!  Manufactured from engineering grade nylon to ensure a long life of burning through bricks of ammo.

For M11/NINE SMG use ONLY.  NOT for semi automatic pistol.  

Dimensions: 0.825″ thickness.
