BD-180 Blast Deflector & Kits

Our new BD-180 Blast Deflector is an inexpensive easy to install upgrade for short barreled rifle and AR Pistol applications that works with standard 1/2" threaded Mil-Spec flash hiders. It redirects high pressure concussion, flame, and hot muzzle gasses forward and away from the shooter and bystanders. This is especially important when shooting in tight quarters or in a line at the range.

Please see below for technical specifications and compatibility.

The BD-180 is unique in it's application because it is trapped between the muzzle device and the barrel. It can be used in place of, or in conjunction with, a crush washer. At 1.35 inches in diameter and weighing in at a mere 2 ounces it will fit inside most low profile or lightweight fore-ends without adding significant weight to the muzzle. Another advantage is the use of a wrench inside the flash hider for installation. This gives the installer the flexibility to attach the BD-180 before or after the fore-end has been assembled.

Kits are available to pair with your pre-owned 1/2" threaded flash hider, or as a complete combination package of a BD-180, Flash Hider, Installation Tool, and Crush Washer (select kits only). Please select whichever options best suit your needs from the drop down window.
