The AMTAC CQB Series

The CQB Series over-barrel suppressors are designed around the AR15 platform
and add only 3.7” to your rifle’s overall length.

The CQB-Series suppressors add only 3.7″ to your rifle’s length for better maneuverability in tight spaces. We use aerospace-grade CNC technology to machine the entire baffle structure out of a single piece of 17-4 PH stainless steel for extreme durability.

Available in both 4″ and 6″ over-barrel versions, the CQB-Series suppressors are compatible with a wide range of barrels and gas systems. Check the compatibility page to see which one is best for your rifle.

THE BENEFITS OF OVER-BARREL DESIGN

We use aerospace-grade CNC technology to machine the entire baffle structure out of a single piece of 17-4 PH stainless steel for extreme durability and reliable accuracy. The over-barrel chamber reduces sound without adding excessive length (adds only 3.7” to a rifle’s overall length), and drastically decreases gas blowback when used on a direct impingement rifle. This enables better maneuverability in tight spaces and brings the weight closer to the center of the rifle to reduce fatigue and speed up target transitions.

Available in two different versions to accommodate a wide range of rifle configurations, the CQB Series features direct-thread attachment and can be fit under many free-float hand guards.
