Lantac Dragon Muzzle Brake 9Mm 13.5X1 Wolfman
The Lantac Dragon muzzle brake for 9mm is a precision-engineered recoil management device built for shooters who demand repeatability and control. Designed specifically for the 13.5x1 left-hand thread pattern, this brake leverages a patented Short Energy Pulse system to minimize felt recoil and muzzle rise—keeping your follow-up shots on target even during rapid fire. Whether you're running a SIG MPX, training at the range, or testing full-auto performance, the Dragon delivers the velocity stability and shooter comfort that serious 9mm shooters expect.
What sets the Dragon apart is its forward compatibility with suppressed shooting. The brake features a fully licensed Dead Air Keymo mount, so you can stack a Dead Air Wolfman suppressor without voiding your warranty or compromising the system's design integrity. Lantac machines every brake on Swiss lathes from hardened AISI4140 steel, then nitrifies the parts to AMS2753D standards for corrosion resistance and longevity. Each unit comes serial-numbered, ships with a timing shim set for precise indexing, and includes a Taper Lock adapter to get you ready for the range immediately.
This is a USA-made component that respects both the shooter and the suppressor platform. The engineering shows in the details: the hardened steel core, the thoughtful mount licensing, the included accessories. If you're building a 9mm platform around the Wolfman or simply upgrading your brake game, the Dragon is built to last and perform.
