Aggressive, scallop-type cuts deliver superior gas dispersion to help stabilize the muzzle during periods of sustained fire. Special internal blast chamber with side-facing ports helps reduce recoil with no adverse effect on gas system function. Also provides enough flash suppression to keep flash out of the shooter’s line of sight. Wrench flats directly over the internal threads ease installation. All models include a peel washer for precise indexing of the side ports. FSC556 fits rifles chambered in .223/5.56mm. SM566 has all the same great features of the FSC556 Tactical Compensator, plus mounts the Knights QDSS-NT4 suppressor as well as the Gemtech HALO suppressor. FSC556 QDSS serves as mounts for the Yankee Hill Machine Phantom and Knight Armament QDSS-NT4 quick-attach/detach sound suppressors. Both provide the same compensation/flash reduction as the standard FSC556 when the suppressors are removed. FSC30 fits rifles chambered in calibers from 6.8mm up to .308/7.62mm. Threaded for muzzles with 5/8"-24 tpi thread; includes a screw-on adapter for installation on rifles with ½"-28 tpi threads. The CQB is designed primarily for entry teams and other operators working in confined spaces like buildings. Directs the entire force of the muzzle blast forward to protect the shooter and team members next to him from hot gasses and concussion. Also helps suppress muzzle flash and provides some recoil compensation. The TTO features all of the compensation of the FSC556, but does not possess the flash suppressing tines of the FSC556. This design was produced for competitive shooters that are looking for the shortest possible package without sacrificing recoil reduction and compensation performance.
