FOX CREEK ARMS FX556K-SS

Overview

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, 6x47, 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.
