Abstract
The blast deflector may be used with a barrel and with a firearm. The blast deflector threads onto the end of a barrel of the type that has an outer tube and an inner tube defining a chamber thereinbetween. The blast deflector provides for a sealing connection between the outer tube and the inner tube. The blast deflector has a plurality of channels radially spaced around a central passage. Each of the channels is sized to define an axially aligned member that extends inwardly but is spaced away from the central passage to define a receiving chamber. The receiving chamber has length of about 2 to about 4 times the diameter of the projectile. The propellant gases enter the receiving chamber and are directed out through the transverse channels rearwardly which are formed at an angle of about 60.degree. relative to the axis of the central passage.
