Baffle suppressors block expanding gases from fired rounds. This increases barrel and chamber pressure as much as 350psi causing significant weapon malfunctions and toxic blowback into the shooter’™s face.

OSS suppressors add less than 30psi to backpressure while redirecting and venting expanding and toxic gases forward out the muzzle and away from the shooters face.

As gas expands rapidly backward in operating systems using a baffle suppressor, bolt velocity (BV) increases as much as 22%. This negatively impacts weapon performance and shooting experience with increased felt recoil, muzzle rise, and multiple malfunctions.

OSS suppressors do no™t increase bolt velocity (on some platforms BV is actually reduced), and dramatically reduces felt recoil and malfunctions.

Baffle suppressors do provide flash reduction, but they often create a first round plume and sound pop. And with extreme firing conditions, baffle suppressors have been shown to lose flash suppression effectiveness as heat and carbon buildup increase.

OSS suppressors effectively mitigate flash and sound signatures in all conditions and rates of fire.

Because baffle suppressors block expanding gases, the energy from rounds fired gets trapped causing high and prolonged heat and degraded suppressor life. Thermal gains spike quickly with semi-auto fire, and even faster with full-auto fire.

By allowing gas to expand and energy to transfer forward at a natural rate, OSS suppressors deliver effective thermal management with some models experiencing 70% lower temperatures than comparable baffle cans.
