The Muzzle Device For Your Favorite Dead Air Sandman KEYMO Silencers

The Lantac Dragon Dead Air KEYMO Muzzle Brake can now allow shooters to enjoy advanced weapon control with the ability to mount the entire range of Dead Air Sandman KEYMO silencers to their firearms.

It features an exclusive design fully licensed from Dead Air, precision manufactured on Swiss lathes, and machined from AISI4150 steel. This muzzle brake is hardened to 48-52Rc (Rockwell C) and QPQ (Quench Polish Quench) Nitrided to AMS2753D standards for enhanced corrosion resistance and improved lifespan.

Unique Short Energy Pulse System

The Lantac Dragon Dead Air KEYMO Muzzle Brake also features a unique Short Energy Pulse system that reduces the 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 that ensures every shot falls accurately on the target.

Ships with a timing shim set. Lantac recommends the use of semi-permanent thread locker Rocksett, sold separately.

Features:

  • Designed for .223/5.56
  • DIA Body: 0.824” MOUNT: 1.080’’
  • Serial Numbered for Quality Control
  • Includes appropriate shim set for timing the brake
  • Dead Air KEYMO suppressors
  • Does NOT work with BMD, Blast Mitigation Device
