Lantac USA BMD Gen2 .30cal Blast Mitigation Device with A3 Adapter Collar

The Lantac USA® BMD® Gen2 .30cal Blast Mitigation Device with A3 Adapter Collar features a patent pending design that features unique through ports that connect your muzzle brake's vertical vents to the outside atmosphere allowing your brake to function properly. This blast mitigation device uses Disruptive Venting™ which is 2 Trefoil threaded ports that disrupt gas flow to reduce your rifle's vertical flash signature while allowing the BMD to control muzzle rise. This muzzle device also helps to direct concussive muzzle blast forwards down range away from fellow shooters. Radial teeth at the exit aperture help to disrupt blast gas as it exits the device and mounts to the collar via a rotation lock ring. This muzzled device features 4140 chrome molly vanadium steel construction with a corrosion-resistant QPQ nitride finish. The BMD® is mounted to the Dragon Muzzle Brake through the use of the adapter collar that is designed to function with ONLY the following non pinned & welded LANTAC Dragon™ Brakes: DGN762B (7.62/.308) Does not work with DGNAK47B Dragon Brakes. Does not work with A1 adapter collars. Made in USA.
