It seems like almost ever muzzle device maker is releasing their own version of a muzzle device shroud. LANTAC showed off their version at the 2015 SHOT Show and it looks pretty good. Called the BMD, or Blast Mitigation Device, it works with their Dragon brake and it has a pretty unique feature that sets it apart from the rest of the shrouds on the market. LANTAC has incorporated vertical ports on the top of the shroud to allow their Dragon brake to function just as effectively as it does without the shroud. There’s still no definite word on a price or release date however, check out lantac-usa.com for more info.
LANTAC BMD, Blast Mitigation Device. There have been many derivatives of the first blast shield designed by Simplistic Shooting Solutions and or Kineti Tech years ago. Including QD attachment systems and diffuser holes as seen in Ferfrans and the Spikes Tactical HVS designs. With Gemtech, Griffin and MMC also fielding good products.
The BMD is our take on this type of device, with a few changes from our original concept that was tabled at the time we designed our Dragon brake.
One of the most important features for us was vertical porting that would allow the Dragon brake to continue to shoot as efficiently as it does without compromise. The other was gas flow direction and turbulence. Internally the BMD features an angled shoulder that allows gas to flow smoothly into the diffuser sections of the outer cylinder and also across the many teeth at the opening. The diffuser holes are also strategically position at the sides and top of the BMD but NOT the bottom, this also assist in muzzle climb management, its the same principle as found in the A2 compensator.
The BMD is also retained by 2 spring loaded catches on either side, so can be ‘stripped’ forward from the brake very quickly if required.
