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 new Gen2 system utilises Disruptive Venting™, two Trefoil threaded ports distrupt gas flow and reduce vertical flash signature while still allowing the device within the BMD® to control muzzle rise. 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 a rotating lock ring.

Review by Troy S. on 8 Sep 2017review stating Great product and great dealing with Rainier.
I received a defective unit...it happens. The return process was easy and went smoothly. I'd definitely recommend Rainier as a vendor to deal with.

nitely better for the people around me when shooting my AR and I haven't noticed much, if any, degradation in my grouping. The construction of the unit and fitment to the collar is smooth and snug, so no rattling. There is also the fact that it looks cool as hell in my book.

The dragon is a great product and the BMD is an even better addition. It really does help with side blast concussion and seems to direct the sound away from me as well. Training around others isn't so obnoxious now. If you buy this product take your time installing the collar. If you don't tighten the screws evenly it WILL NOT fit the BMD.

Review by Dave G. on 16 May 2017review stating Love that I can easily
Love that I can easily switch it from my ar10 to my ar15 with the quick release and a2/a3 collars on my Lantac Dragons but really irritated that the black finish was worn through on the top and sides apparently from movement inside it's plastic box
Q: Will the Lantac BMD Type A fit the Lantac Dragon w/ QD Gemtech Suppressor Mount? The details say it's designed for the DGN556B, whereas the one w/ the Gemtech mount is part #DGN556B-QM. So I'm not sure if they are compatible or not. Anyone know?

A: The BMD will not fit Lantacs with the Gemtech lugs on them. The Gemtech blastshield will however.

Q: Hi i recently sent my upper to you guys to swap out my pinned and welded flash hider with Lantic Dragon DGN556B Muzzle Brake to make it legal here in California, Do you know using Lantic BMD Type A would be legal since it's not a suppressor ?? Sorry laws are very confusing ! Thanks.

A: I don't work for Rainer. If you're trying to get a featureless build, the BMD would count as a flash hider. Long story short, if you're going featureless (regular mag release), no, the BMD would not be legal. If you opt to register or use a maglock device, then yes, the BMD is legal.
As for the lantac dragon itself, in order to be featureless, I believe the muzzle device on your AR must be a muzzle brake ONLY, and whether the dragon is only a brake or a brake/flash hider combo is up for debate.

Q: I have a LanTac Dragon on my duty 10.5" AR reconfigured for 300Blk. What parts would I need if I purchased your BMD?

A: I am not sure but if the same lantac dragon for a 223, it will fit since it attaches directly to the Dragon itself
