UK Arms ACC Tactical 4.3" CCW Barrel Extension w/ Flash Hider, Rose Gold

The ACC Tactical CCW Barrel Extension is a mock suppressor built for pistol-caliber carbines and other replicas with 14mm CCW threading — the most common muzzle standard on AEGs and GBBs. At 4.3 inches, it extends the profile enough to look the part without turning a compact setup into something that no longer fits in your gun bag.

It’s steel and aluminum, so it has the weight of a real muzzle device rather than the hollow feel of cheaper all-polymer options. The Rose Gold finish is a deliberate two-tone look — if you’re running a non-standard colorway or want a barrel that stands out in your loadout, this is that piece.

The 14mm CCW threading lets you screw it on and off without tools, which is useful if you’re rotating between fields with different rules about mock suppressors, or just want to go back to stock length. Threads directly onto standard 14mm CCW outer barrels, so no adapters needed. It’s a cosmetic and profile upgrade — it doesn’t change velocity, accuracy, or internals.

Ships as a single mock suppressor. Thread tape is recommended to keep it secure during play.
