Lantac
The Lantac BMD Gen2 blast mitigation device with A2 adapter collar is a muzzle brake accessory designed to reduce concussive blast and muzzle climb for AR-platform shooters without sacrificing the core function of your existing brake. If you run a DGN556B Dragon muzzle brake on your 5.56 rifle and want to keep blast signature down—especially during team drills or at shared shooting facilities—the BMD Gen2 uses a patent-pending design to redirect concussive energy downrange and away from shooters nearby while preserving the vertical recoil control your brake was designed to deliver.
What sets the BMD Gen2 apart from simpler blast shields is its engineering: internal 'through' ports connect your brake's vertical vents directly to atmosphere, allowing the brake's muzzle climb mitigation to work as intended rather than being choked off or degraded. A series of diffuser grids near the top of the shield encourages gas to exit both upward and forward, further aiding recoil management. Radial teeth around the exit aperture disrupt blast gases as they leave the device, scattering the concussive wave instead of directing it rearward toward your shooting line.
The Gen2 mounts via a collar adapter that clamps to Dragon brakes measuring between .855" and .872" in outside diameter. Rugged dual clips secure the shield to the collar; both must be depressed simultaneously to remove it for cleaning or brake service. The device ships with Rocksett thread-locking compound, which must be applied to all mounting set screws—this is critical for keeping everything tight under sustained fire.
Built from milspec gun steel with black oxide finish and weighing just 7.3 ounces with hardware, the BMD Gen2 adds minimal bulk while keeping your Dragon brake's performance intact. Made in the USA and backed by complete instructions, this is a practical choice for shooters who need quieter muzzle signature without compromising recoil control.
| Caliber | 5.56×45mm / .223 |
| Designed For | DGN556B Dragon Muzzle Brake only |
| Material | Milspec gun steel |
| Finish | Black oxide |
| Length | 2.570" |
| Body Diameter (largest) | 1.600" |
| Body Diameter (smallest) | 1.185" |
| Width at Mounting Clips | 1.785" |
| Adapter Collar Brake Diameter Range | .855" to .872" |
| Weight (including hardware) | 7.3 oz |
The BMD Gen2 is designed specifically for the Lantac DGN556B Dragon muzzle brake. The included adapter collar fits brake bodies measuring .855" to .872" in outside diameter. Before ordering, measure the diameter of the circular section marked with the LANTAC logo on your brake to confirm fit. Sizes outside this range may require gunsmith work or may not be compatible with this device.
No. The BMD Gen2's patent-pending through-port design allows your muzzle brake's vertical vents to function normally, so the brake's muzzle climb mitigation is preserved. Diffuser grids and the shaped exit aperture actually assist muzzle control by directing gas upward and forward in addition to the brake's original function.
The BMD Gen2 ships complete with the blast mitigation device, adapter collar, dual mounting clips, and a vial of Rocksett thread-locking compound. Full assembly and installation instructions are included. Rocksett must be applied to all mounting set screws before installation.
Two rugged clips secure the BMD Gen2 to the adapter collar. Both clips must be depressed simultaneously to detach the device from your brake. This design keeps the shield securely in place during use while allowing straightforward field removal when needed.
