The Lantac Dragon Muzzle Brake for .223/5.56mm rifles is a purpose-built recoil management tool designed for shooters who demand precision control during rapid fire and competition. Built around Lantac's patented Short Energy Pulse system, this .223 1/2-28 threaded brake substantially reduces both recoil and muzzle rise, letting you keep follow-up shots on target without fighting the gun. Whether you're running a competition AR, a precision rifle, or just want better control at the range, the Dragon delivers the stability serious shooters expect.
What sets the Dragon apart is its Dead Air XENO HUB-compatible design—a fully licensed mount that lets you attach Dead Air suppressors without compromising your suppressor's warranty. The brake ships with a timing shim set to dial in zero-timing if needed, and Lantac machines every unit from hardened AISI4140 steel, then nitriding it to AMS2753D standards for corrosion resistance and durability. It's precision-made on Swiss lathes and serial-numbered for quality control. Made in the USA, this is a brake built to last through thousands of rounds.
The Dragon works for everything from semi-automatic tactical shooting to full-auto platforms, making it a versatile choice for shooters stepping up from basic flash hiders. If you're pairing it with a Dead Air XENO suppressor, note that Lantac recommends applying Rocksett semi-permanent thread locker during installation (sold separately) to keep the brake locked in place. Always follow Dead Air's guidance when running a suppressor on the XENO HUB mount.
