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.
