Helical Flutes 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. Significantly reduces muzzle flash to help preserve your night vision. Provides highest degree of efficiency using NATO spec ammunition. Features four, 15° helical flutes with the sharp edges removed to reduce snagging. Install using the OEM, flash suppressor nut; requires no modifications to rifle. Fits M14 and M1A rifles.
