Helical Flute Dissipate Gas, Hide Muzzle Flash

Four, specially angled flutes hide nearly 100% muzzle flash, even during full-auto fire, by dissipating gas and retaining unburned powder for increased residual burn. Constructed of the same 8620 bar stock steel used in the manufacture of AR-15/M16 bolts and carriers, then heat-treated to provide a high-strength core and tough, outer shell. Special, helix design helps align exiting barrel gas to improve accuracy with all bullet types. Designed for Kalishnikov-style rifles with 14x1mm Left-Hand barrel threads. Grooved base ring allows the use of a Blank Firing Adaptor (BFA) used by law enforcement trainers. Left-hand flutes will not come loose during sustained fire.
