The Lantac Dragon Muzzle Brake (brand part number DGN556B-DA) is a .223/5.56 AR-15 muzzle device built to control recoil and muzzle rise while staying compatible with Dead Air’s suppressor mounting system. Lantac designed the Dragon brake’s signature shark-fin porting to redirect propellant gas efficiently, taming muzzle climb during rapid strings of fire. Threaded 1/2×28, it fits standard 5.56 barrels and is built to accept a Dead Air KeyMont-style suppressor mount, letting shooters run the brake day-to-day and add a suppressor without a separate mount swap. It is a proven option for AR-15 owners who want both recoil control and suppressor-ready mounting in one muzzle device.
