OSS BPR 114 Titanium 5.56mm OTB suppressor with SRM 4

The OSS 5.56mm OTB suppression systems are customized for a wide range of 5.56mm / .223 platforms including all AR15 / M16 / M4 and other variants. OSS 5.56 OTB suppressors are a 2 component system featuring: Back Pressure Regulator (BPR) Signature Reduction Module (SRM). The OSS suppression system combines a BPR (Back Pressure Regulator) and SRM (Signature Reduction Module) to deliver hearing safe sound and flash signature suppression without adverse effects caused by baffle suppressors.

The OSS Flow-Through suppression system redirects the toxic gas and carbon forward while only adding 30psi to barrel pressure – a relatively low 2.5x increase!. OSS suppressors dramatically reduce felt recoil and muzzle rise. OSS Flow-Through suppression systems eliminate first round flash. The OSS Flow-Through suppression system provides superior heat management by allowing for the gas and energy transfer to occur at a natural rate – traveling as much as 40” before exiting the muzzle. The result is 70% lower temperature than with baffle suppressors and a more rapid return to normal temperature after firing.

Superior Performance
Less than 5% bolt velocity increase fully suppressed. Less than .5 MOA / .15 MIL POI shift. Reduction of visual signature – less than .02 Lux of flash. No initial bloom or secondary flash. Low pressure, low temperature solution – 1/3rd the operating pressure, 30% lower operating temperature. 90% reduction of high velocity toxic gasses expelled at the shooter. Hearing safe at the shooters ear. Octagon design for enhanced mirage mitigation.

Superior Modularity
Quick Disconnect (QD) self-torqueing design. Caliber convertible. Interchangeable Signature Reduction Modules (SRM) providing multi-mission capability. Customizable interior design enables tuning specific suppressors for specific platforms. Allows for full use of SIM/UTM and frangible ammunition. Superior Sustainability.

Superior Sustainability
User serviceable in the field. 100% sustainable and serviceable. Will not degrade rifle service life.

OSS suppression systems can deliver sound levels as low as 138dB – well below hearing safe. And with OSS’s modular suppression systems, operators can combine different BPRs and SRMs to achieve the sound signature required for their mission.
