Area 419 Hellfire Linear Flash Suppressor Features The Area 419 Hellfire Linear Flash Suppressor is built as half flash hider and half blast forwarding device giving carbine SBR and AR pistol owners a muzzle solution tailored specifically to shorter barrel lengths. Rather than venting gas and flash to the sides where it can disturb the shooter and bystanders the linear design pushes concussion and flash forward and away from the firing position. Constructed from 17-4 PH stainless steel and finished in a black nitride coating the device is built from two parts assembled to function as a permanent installation. Its bore aperture accommodates calibers up to .458 giving it the versatility to serve across a wide range of rifle and pistol caliber platforms. Measuring 6 inches in length and threading onto a standard 5/8x24 pattern this device ships with the adapter needed for a secure installation on compatible barrels. Area 419 developed the Hellfire line after requests for both linear blast forwarding devices and effective flash hiders ultimately deciding shooters should not have to choose one or the other. This combination approach gives shooters reduced visible flash signature along with the forward concussion mitigation benefits that make shorter barrels more comfortable to shoot. For anyone running a carbine SBR or AR pistol who wants a purpose built muzzle device rather than a compromise design the Area 419 Hellfire Linear Flash Suppressor delivers both functions in one unit.
