Using aerospace-grade CNC technology, we’re able to machine the entire baffle and the mounting threads out of a single piece of 17-4 PH stainless steel. This monolithic design features no structural welds, which lowers weight and increases durability. Threading the baffle directly to the barrel allows for ultra-precise concentricity resulting in a rock-solid return to zero and minimal POI shift when shooting unsuppressed.

The over-barrel design of our CQB-series suppressors adds only 3.7″ to your rifle’s length to increase maneuverability in tight spaces. Moving the suppressor closer to the center of the rifle reduces swing weight for faster transitions between targets, and the reduced recoil minimizes sight movement for quicker follow-up shots.

Because the CQB series uses a direct-thread attachment, you can mount it under most full-length free-float tubes in order to maintain a short overall length while adding room to mount lights, front sights, or a bipod, and unlike most center-fire suppressors, the CQB features a user-serviceable design that can be disassembled and cleaned after use in harsh environments.
