OSS Operators Suppressor System BPR and SRM .30 cal Core

Regular Price: $1,499.95

Product Code: OSS_BPR_SRM30

Incorporating several patented innovations, the BPR1™ is at the heart of the OSS System. This device controls expanding gases in a way never before performed. This control allows for the “tuning” of every device to the intended weapon’s operating system, barrel length, and caliber. Controlling the expanding gases, instead of simple baffle trapping, eliminates up to 95% of the back pressure created by traditional suppressors.

Integral to the BPR1™ capture and control internal design is a patented self-tightening function. Every time you fire the weapon, the device tightens, it is impossible to loosen a BPR™ through shooting

The BPR1™ Over The Barrel suppressor offers several mission enhancing capabilities. The difference being OTB allows us to add minimal length to your weapon, 3.9″, and transfers the axis point of your weapon back towards the center point, making it easier to control/drive your weapon. Essentially, providing added capability with far less change to the balance each shooter is accustomed too with their weapon

The BPR1™ is also multi-caliber. For example, you can purchase a FHMB (Flash Hider Muzzle Brake) in any caliber from 5.56 through 7.62, and attach the BPR suppressor to every FHMB caliber. THE FHMB IS NOT A SUPPRESSOR COMPONENT

The length of the BPR1™ is determined by the mission-specific signature reduction requirements, caliber and weapon system.

The Signature Reduction Module as the name implies, this device was designed and engineered specifically to reduce visual and sound signature. The SRM™ is placed in line after the BPR™. The SRM™ can be built to achieve whatever signature level reduction is necessary. Generically speaking for a standard M4, an SRM™ 4 will bring the decibel level well below ear safe. As with all OSS modular components, it is for the operator to decide which components offer the greatest advantage for each mission or operational environment.

The size of the SRM™ is determined by the mission-specific signature reduction requirements ranging in length from 2.3 to 5 inches. As with the BPR, each SRM is caliber convertible and can be used with your BPR on multiple weapon platforms. This capability also allows for the use of all types of training ammunition.

This BPR and SRM combo is chambered for .30cal
