Description
The LANTAC Dragon is one of those muzzle devices that pulls double duty and does both jobs well. On its own, it's a serious recoil-taming brake for 9mm and .350 Legend rifles with a 1/2-28 threaded barrel. Thread on your Dead Air Wolfman using the built-in KEYMO mount, and it becomes a rock-solid suppressor host. That flexibility is a big reason folks keep reaching for the Dragon over a plain brake.
What the Dragon KEYMO Brake Does at the Muzzle
LANTAC's Short Energy Pulse design is the heart of this thing. It works to shorten the length of recoil so the energy from one shot doesn't overlap into the next and push you off target. The result is a flatter, straight-back recoil impulse instead of the muzzle wanting to climb, which makes your follow-up shots faster and keeps your sights on the target between rounds. Two large side ports handle the bulk of the gas while smaller top ports fight muzzle rise.
Built to Take a Beating
Every Dragon is precision machined on Swiss lathes from AISI 4150 steel, then hardened to 48-52 Rockwell C and QPQ (Quench-Polish-Quench) nitrided to AMS2753D standards. That process gives you strong corrosion resistance and a long service life, which matters a lot when you're running a suppressor and dumping heat into the device. Each brake is serial numbered for quality control and carries the Wolfman-black finish that pairs cleanly with most builds. It measures roughly 2.3 inches long and weighs in around 3.7 ounces.
Wolfman-Ready Without the Warranty Worry
The KEYMO mount on the Dragon is fully licensed from Dead Air, so mounting your Wolfman over it won't affect your suppressor warranty. It ships with a timing shim set so you can dial in perfect alignment during install, and LANTAC suggests using Rocksett thread locker (sold separately) to keep everything locked in place. Made in the USA and backed by a lifetime warranty, this is a proven pick for anyone building a suppressor-ready pistol-caliber setup.

Frequently Asked Questions
Will the Dragon KEYMO brake let me run my Dead Air Wolfman without voiding the warranty?
Yes. The KEYMO mount on the Dragon is fully licensed from Dead Air, so mounting your Wolfman over it keeps your suppressor warranty intact. It's built specifically to work as a host for KEYMO-mounted cans.
Does the LANTAC Dragon come with timing shims?
It does. Each Dragon ships with a timing shim set so you can index the brake correctly and get the ports oriented right during installation. LANTAC also recommends Rocksett thread locker, which is sold separately, to keep it secured.
Can I use the Dragon as a standalone muzzle brake without a suppressor?
Absolutely. It works as a full-featured brake on its own, using LANTAC's Short Energy Pulse design to cut felt recoil and fight muzzle rise for faster follow-up shots. The KEYMO mount is just there for when you want to add the Wolfman later.
What barrel does this fit and what caliber is it made for?
This version threads onto a 1/2-28 barrel and is built for 9mm, and it also works well on .350 Legend rifles. Make sure your barrel is threaded 1/2-28 before ordering, since LANTAC offers other thread pitches for different platforms.
