KAC’s Pressure Reduction Technology (PRT) Signature Reduction Device line blends the proven durability and acoustic performance of the previous generation of KAC suppressors with pressure reduction design.

These suppressors are specifically engineered to release the majority of the pressure contained in the device and bore prior to the operating system beginning extraction, which significantly reduces the negative effects of suppressor integration, and reduces felt recoil compared to a traditional suppressor with the same level of sound reduction.

Muzzle flash, and specifically first-round flash, has also been directly addressed and minimized with the PRT design. The Quick Disconnect (QDC) mounting method ensures reduced carbon-lock, as well as minimal but repeatable point of impact shift when transitioning between suppressed and unsuppressed configurations.
