The Patriot Suppression Technology Suppressors are 3D-printed, monolithic suppressors, designed for extremely low backpressure. They feature a patent-pending helical, three-chamber core that vents gas forward out the front of the suppressor, reducing blowback, keeping your rifle running cleaner, and controlling cyclic rate — without sacrificing suppression, recoil, or flash reduction. Patriot Suppression Technology Suppressors are built around a simple idea: suppression should not punish the shooter or the firearm.
