FX556K-SS
The FX 556K-SS is a compact, 17-4 stainless steel suppressor designed for applications where every inch matters, like short-barreled rifles (SBRs). Despite its smaller size, it delivers exceptional sound suppression and is versatile enough to handle both 5.56mm and 6mm cartridges (6mm cm, 6ARC, 6×47, 243 etc.), thanks to its slightly oversized bore. Rated for responsible full-auto use with a cooldown period after 100 rounds, the FX 556K-SS combines durability, performance, and a reduced footprint for shooters who need a reliable, compact suppressor.
