Sharp Shooting Indoor Range


Close Quarters

Developed for extremely short rifles to mitigate muzzle blast in close quarters situations while increasing rifle control.


Removing material where we could without damaging functionality, the PWS CQB compensator is very lightweight.

In SWAT applications where shooters are generally firing indoors, muzzle compensators create too much overpressure. The CQB combats this by projecting the blast forward, limiting the concussion felt by the team.

Weight 1 lbs
Dimensions 5 x 3 x 1 in

  1. This comp is great for shooter that shoot close to teammates, indoors or looking for the gases to go forward. I creates a little more push on the shooter. It did not effect my follow up shoots. I product is worth a try

  2. A product that does what it says it will do!
    I purchased the CQB for a 7.5″ barreled AR15 pistol. I was hesitant to spend so much on a muzzle device for fear that it wouldn’t live up to expectations, leaving me feeling like I had wasted a lot of money. That is not the case at all!

    Every SBR and AR pistol I’ve shot and have been around has been brutal (blast) at worst, and “comical” (flames) at best.
    While fireballs are funny at the range, I was really trying to avoid them if possible.

    After completing my build I couldn’t tell the difference in sound/blast between the pistol and my 16″ carbine, and I saw no fireball whatsoever – not even a spark.
    I shot it a bunch today with friends and we were all impressed with the lack of flash/flames/concussion.

    To say that I am happy with my purchase of the PWS CQB compensator is an understatement.

  3. Law Enforement background.

    Used on 7.5″ & 16″ barreled weapons.

    Keeps muzzle blazt forward. Keeps barrel level/flat on auto fire for thoughts with class three licenses or access to military or police firearms. Keeps muzzle flash low or unseen depending on barrel length. Good for indoor fire or around combustible materials and in low light conditions, when shooter location is a concern. All in all, a well thought out design for police firearms, military or self defense.
