The Blastphemy kit includes one (1) Blastphemy and one (1) Flash Hider-QD 556 1/2x28. 

The blast deflector directs the blast forward, shielding the shooter and bystanders from overpressure and micro-concussions. It also functions as a thread protector for your muzzle device, making it perfect for shooting from cover or in the prone position.

*The Blastphemy is NOT compatible with the Bannar or Comp-STS muzzle devices.
