OSS 5.56 Flush Mount suppression systems are ideal for any 5.56 platform that does not have enough barrel length to allow for an OTB suppressor including AR-15, SBRs (short barreled rifles) and other 5.56 variants.

OSS Flush Mount suppressors attach to the front end of our FHMB-2 (Flash Hider Muzzle Brake) muzzle devices. You can purchase a FHMB-2 in 5.56, 7.62 and other calibers. 7.62 models can accommodate 5.56 and 7.62 suppressors.
