LanTac Dragon Muzzle Brake Features The LanTac Dragon Muzzle Brake uses a patent pending Short Energy Pulse system that shortens the length of recoil so that repeating shot energy cannot overlap and knock the shooter off target. This design allows full auto fire with massively reduced recoil and muzzle climb meaning shots stay on target even during rapid strings of fire. Machined on Swiss lathes from AISI4150 steel the brake is hardened to 48 to 52 Rockwell C and then QPQ nitrided to AMS2753D standards for enhanced corrosion resistance and a longer service life. Threaded 1/2x28 UNEF the brake is a direct fit for standard AR15 M16 and M4 pattern rifles chambered in .223 Rem or 5.56 NATO. Beyond recoil management the Dragon brake is fully licensed to mount the Dead Air Xeno HUB giving shooters a direct repeatable suppressor mounting point without affecting their suppressor s warranty. It ships complete with an appropriate crush washer and a timing shim set to ensure correct alignment when torqued down on the barrel. LanTac recommends the use of a semi permanent thread locker during installation to keep the brake properly timed and secure. This combination of serious recoil control and suppressor readiness makes the Dragon Muzzle Brake a strong choice for AR shooters who run a can and want their brake to double as a mount.
