The BMD®, Blast Mitigation Device is a unique blast shield that allows the muzzle brake contained inside it to continue to function as normal with regard to muzzle climb mitigation. The patent pending design features unique 'through' ports that connect the muzzle brakes vertical vents to the outside atmosphere. This feature allows the brake to function while within the device unlike other system that alter the way the original device works and inevitably remove or massively reduce efficiency. The device also features sets of 'diffuser' grids positioned towards the top of the blast shield that assist in allowing gas to vent upwards as well as forwards at the time of firing, assisting even further in muzzle control. Concussive muzzle blast is directed forwards, down range and away from other shooters and team mates. Radial teeth at the exit aperture help to disrupt blast gas at it exits the device. The BMD® mounts to the collar via the use of two rugged clips that must both be depressed together in order to remove the device from its mount.
The BMD™ is mounted to the DGN556B™ Muzzle Brake through the use of an adapter collar. The collar is designed to fit as wide a range of brake outside diameters as possible and can effectively be mounted within the following size range:.855'' to .872'' Diameter. Diameters outside the ranges listed may need additional gunsmith work to be fitted or may not be used with this product. The device ships with a vial of Rocksett that must be used to ensure all mounting set screws are retained in place when the adapter is mounted to the brake.
This device comes with the A1 mounting collar that is designed to function with muzzle devices that have been pinned and welded including the LANTAC Dragon™ DGN556B. Can also be used on devices that have not been pinned and welded.
