Lantac DGN9MMC Dragon 9c SIG MPX 9mm Steel L:2.66|0.9 Diameter in.

The Lantac Dragon 9mm muzzle brake for SIG MPX is engineered to cut recoil and muzzle rise without the bulk. Built from hardened milspec steel with a nitride finish, this compact brake measures just 2.66 inches long and threads onto 13.5×1 left-hand SIG MPX barrels. At under 3 ounces, it's light enough that you won't notice it hanging off the end of your gun, yet substantial enough to make rapid follow-up shots and full-auto strings controllable and predictable. The design emphasizes keeping your sight picture intact shot after shot—critical whether you're running drills at the range, hunting in close quarters, or training on a PCC platform.

What sets the Dragon apart is its Short Energy Pulse design. Rather than trying to absorb recoil through sheer mass or overly aggressive port angles, this system manages the timing and direction of expelled gases so that each recoil impulse completes before the next round fires. That means no stacking of recoil forces, no cumulative climb, and no fighting the gun to stay on target. In practical terms: faster splits, tighter groups, and less fatigue on longer training sessions.

Made in the USA and serial numbered for quality control, the Dragon is a no-frills tool that does one job well. Nitride steel stands up to the corrosive byproducts of 9mm and will handle suppressed fire without fouling or wearing prematurely. If you run an SIG MPX 9mm and are tired of chasing your sights uprange, this brake delivers measurable improvement without compromise.

Yes. The Lantac Dragon is designed for SIG MPX barrels with 13.5×1 left-hand threads. Verify your barrel threading before ordering to ensure proper fit.

Can I use this brake on a suppressed SIG MPX?

The brake is compatible with suppressed fire. The nitride steel finish is resistant to the accelerated corrosion that can occur when running a suppressor, so long-term durability should not be compromised.

Is this brake suitable for full-auto fire?

Yes. The Short Energy Pulse design is engineered to manage recoil and muzzle rise during sustained automatic fire, keeping shots on target even during rapid strings.
