What you’d expect from Lantac! by Seth, Verified Owner, March 10, 2021
Lantac is one of the better names for AR parts out there. This was no different. The dragon makes a huge difference when shooting. Much less felt recoil. This one here allowed me to mount my Sandman S to it in a matter of seconds! Great product and I...

Great product by Bob, June 3, 2021
I bought this to fit my dead air sandman s and it works great! The machining and finish were extremely nice. The brake does a really good job controlling the recoil as well. I would definitely recommend this product.

Very effective at taming the recoil of my AR 10 by Johnnyonthespot, Verified Owner, March 1, 2026
I run this on my 18 in ar 10. Combined with a rifle sleep gas system and a giessele buffer system the gun runs fast and flat. The Lantac dragon is by far the most effective break on the market. 10/10

great muzzle brake by crash, Verified Owner, January 10, 2026
Great with bringing down muzzle rise. This is usually the first upgrade I do to all of my rifles. I eventually will get a suppressor to go with it.

Product Info for LANTAC Dragon Muzzle Brake with Dead Air KEYMO suppressor mounts

LANTAC Dragon Muzzle Brakeimage

Manufactured to the highest quality standards and featuring a patented design, the LANTAC Muzzle Brake offers improved recoil management and muzzle rise over competitors products.

Its unique Short Energy Pulse system reduces length of recoil so that repeating shot energy cannot overlap and knock the shooter off target.

Full auto fire is possible with massively reduced recoil and muzzle climb, meaning that all shots fall on target.

For the first time shooters can now enjoy advanced weapon control with the ability to mount the entire range of Dead Air Sandman KEYMO silencers to their firearms.

The Sandman range of silencers are manufactured with solid welded Stellite baffle cores and detachable front caps. Exteriors surfaces are Cerakote finished for ultimate durability.

Dragon brakes are precision manufactured on Swiss lathes and machined from AISI4150 steel that is then hardened to 48-52Rc (Rockwell C) and QPQ (Quench Polish Quench) Nitrided to AMS2753D standards for enhanced corrosion resistance and improved lifespan.

The mount design is fully licensed from Dead Air, therefore customers suppressor warranty remains unaffected.

Ships with timing shim set.

Lantac recommends the use of semi-permanent thread locker Rocksett, sold separately.
