Watchtower Firearms finishes the device in black to match a standard AR-15 upper, and the flat-faced crown design keeps the muzzle profile clean and low-snag compared to a device with an open or angular face. Sized specifically for 5.56-caliber rifles, it’s built as a direct fit for a shooter who wants a compact muzzle end without the added length of a longer brake or compensator.
