A muzzle attachment system for a firearm includes a muzzle attachment having a first engagement means, and a muzzle distal portion including a second engagement means, the second engagement means being complementary with the first engagement means. The first and second engagement means cooperate to releasably secure the muzzle attachment to the muzzle distal portion. The first and second engagement means preferably include complementary coarse threaded engagement portions, an annular grooved surface having a plurality of grooves, a grooved surface engagement mechanism, and first and second position stops that abut to form a gas seal. The muzzle distal portion is preferably a flash suppressor, including at least two elongated ports substantially equally skewed from normal relative to a firing axis of the firearm, and substantially evenly distributed around the circumference of the flash suppressor.
