The Rotex 556 K suppressor is our shortest, most compact suppressor in our Rotex line. The K is ideally suited for use on carbines with barrels 14.5-inches and longer, where the K will provide excellent flash and sound reduction while minimizing the overall length and weight added to these longer carbines, without effecting the platforms balance. The K is a hair of 4-inches in length with a DM HUB and just over 5-inches in length with the included Rotex-SF QD HUB.

Constructed using laser bed fusion manufacturing techniques, our traditionally baffled Rotex K rifle suppressor in 5.56 is constructed of 718 Inconel and is completely weldless. Each suppressor is threaded 1.375x24TPI making it fully HUB compatible, should you choose to mix and match your attachment interfaces. The Rotex ships with B&T’s Rotex-SF HUB assembly, which is compatible with all B&T Rotex flash hiders, as well as all of SureFire SOCOM flash hiders, Warcomps and muzzle brakes. The Rotex-SF HUB is machined from titanium bar stock. NATO-Spec A2 and Direct-Mount HUB assemblies are available as accessories items.
