[SHOT 2018] OSS Helical QD Silencers

    In this episode of TFBTV, James speaks with OSS at SHOT Range Day about their 3-piece Gen 4 silencers and their new 1-piece Gen 5 Helical QD suppressors. They are lighter and several hundred dollars cheaper than the three-piece Gen 4.

    From OSS’s Website re: Helical SIlencers:

    SUPERIOR BACKPRESSURE REDUCTION
    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.

    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 do not increase bolt velocity (on some platforms BV is actually reduced), and dramatically reduces felt recoil and malfunctions.

    REDUCED FLASH SIGNATURE
    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.

    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
    While it’s proven that OSS’s Flow-Through technology delivers superior backpressure, bolt velocity and heat reduction, some have questioned OSS’s ability to deliver hearing safe sound suppression comparable to the best baffle suppressors. With the same rifle type, ammo and weather conditions, we recently tested an OSS 5.56 suppressor against three of the leading 5.56 baffle cans. The results should silence any doubts.
