The LANTAC Dragon Dead Air KEYMO Muzzle Brake (brand part number DGN762B-DA) is a .308/7.62x51mm muzzle brake machined from AISI 4140 steel on Swiss lathes, built with a Short Energy Pulse design that shortens the recoil impulse so repeated shot energy doesn’t overlap and push the shooter off target. It’s built with a mount fully licensed from Dead Air, letting shooters run the entire Dead Air Sandman KEYMO suppressor lineup without affecting their suppressor’s warranty. LANTAC hardens the steel to 48-52 Rockwell C and finishes it with a QPQ black nitride process rated to the AMS2753D corrosion-resistance standard, and every unit is serial numbered for quality control and ships with a timing shim set.
