The Official Qube™ compensator is the first pistol compensator that doesn’t require set screws.
The compensator mount threads onto the barrel first and gets torqued down with a wrench.
The compensator mount comes in 1/2 x 28 or M13.5 x 1LH threads to match the host firearm.
The Official Qube™ compensator body slides over the top of the compensator mount and shoulders against a taper. The lock nut threads onto the compensator mount and pinches the Official Qube™ compensator body against a second taper and locks it down which prevents rotation.
