An apparatus for reducing muzzle blast upon discharge of one or more projectiles from a gun includes an outer shell and a first end cap adapted to be secured to a muzzle of a weapon and including provisions for detachably coupling to a first end of the outer shell. The apparatus further includes a second end cap adapted to be secured to a distal end of the outer shell and a plurality of baffles disposed between the first end cap and the second end cap. The plurality of baffles each comprise a bore section having an inner diameter no smaller than a bore of the muzzle and a baffle section coupled to the bore section, the baffle section extending from the bore section to the outer shell.
