This HUXWRX Blastphemy multi-caliber blast deflector is constructed with 17-4 stainless steel and is compatible with all HUXWRX HX-QD Muzzle Brakes and Flash Hiders (up to .338). It was designed to redirect the blast forward protecting the shooter and bystanders from micro-concussions and overpressure. Additionally, it doubles as a thread protector for your muzzle device. It is ideal for shooting against cover and/or in the prone position. Similar to HUXWRX muzzle devices, the Blastphemy is coated with C-Series Cerakote for greater durability and corrosion resistance.
