Only OSS suppressor systems deliver unmatched sound and flash signature reduction, durability and accuracy without negatively impacting your weapon, your mission, your shooting experience or your health.
OSS integrated flush mount systems can be quickly mounted from rifle to rifle – with the STS-Muzzle Brake – providing a versatile and economical suppression solution for today’s hunting and sport shooters with multiple guns.
Only OSS suppressors provide a hassle-free “plug and play” shooting experience. Just attach and shoot. No required weapons modifications, gas block adjustments or gunsmithing to get your gun to shoot the way it was supposed to.
Through Vs Baffles
Reduced Backpressure & Blowback
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 back pressure while redirecting and venting expanding and toxic gases forward — out the muzzle and away from the shooters face.
Reduced Bolt Velocity
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 don’t increase bolt velocity (on some platforms BV is actually reduced), and dramatically reduces felt recoil and malfunctions.
Superior Flash Suppression
Baffle suppressors do provide flash reduction, but they often create a first round plume and sound pop that can reveal an operator’s location. 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.
Reduced Thermal Signature
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.

No Sound Suppression Compromise
Don’t get baffled by competitive sound reduction claims.
Major Gun Co. Engineer
“Backpressure creates serious performance issues for modern weapon systems like ours. With OSS, our guns don’t even know they’re firing suppressed!”
U.S. Army SOF
“Awesome suppressors. Catching a face full of gas and crap with a baffle can will take you out of the fight for even a second. Not a problem with OSS.”
“We picked up the OSS line after this year’s SHOT Show when we experienced the difference between OSS and baffle cans first hand. They’re truly amazing!”
