Detailed Description


Introducing the Wilson Combat QComp-The “Quiet” AR Muzzle Brake

The Wilson Combat Q-Comp has been designed by our compensator experts to greatly enhance recoil control in rapid fire without the harsh blast and flash that other AR-15 muzzle devices exhibit. 

The Q-Comp is a hybrid AR-15 brake/compensator that has been tuned to minimize side-blast and concussion compared to other muzzle devices on the market. This exclusive Wilson Combat design displays almost zero muzzle flash yet retains excellent vertical and rearward recoil reduction with all calibers.

The slotted expansion chamber design of the Q-Comp has no prongs or tines to break off or snag and is Melonite QPQ coated alloy steel for maximum durability and corrosion resistance. The Q-Comp is easily installed on your AR rifle using the included crush washer.

“We have met our goal of development with the Q-Comp design with exceptional recoil control without the excess noise, flash and concussion common to most rifle muzzle brake designs. The Q-Comp will really enhance your tactical rifle shooting experience.”   -Bill Wilson, President of Wilson Combat.

To install the Q-Comp

Secure your AR Barrel in a padded vise or use a tool like the Reaction Rod that supports the upper receiver to prevent damage when torquing your muzzle device.

Remove the old device and discard the old crush washer. Test your Q-comp for a good fit on your threads. Install the supplied crush washer with the cupped side of the washer against the barrel shank so the flat side will be against the rear of the comp.

Screw on the comp using a smooth jawed wrench (13/16" or a 21mm crowfoot attachment) being careful not to torque over approximately 20 ft pounds of pressure. If you are unable to properly index the Q-comp you may need to remove material from the crush washer or crush the washer in a vise to allow more indexing.

The ports should be oriented and centered at the top of the barrel looking down with the writing centered on the underside-the ports direct the gas upward to force the muzzle down-if you install it with the ports pointing down it will push the muzzle up.

Note: Is not compatable with Rock River Arms .458 SOCOM barrel.

Exceeded my expectations
I put one of these on my .458 Socom. Shooting on a bench off sandbags with a 3x scope at 100 yds, I was able to stay enough on-target to see the bullet hole open in the target. In contrast, with the Flash hider that the Q-comp replaced, I always bounced well off target. For this attribute, it exceeded my expectations. I was shooting in a good light, so I cant really comment on the flash-suppressor aspects.
