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.
The very best choice to achieve maximum low light visibility when using tactical entry carbines. Fits AR-15 carbines chambered in 9x19mm with muzzles threaded to the original Colt ½"-36 tpi. Exit hole is properly clearanced to provide minimum blow-by flash without bullet interference. Rigid, unique Vortex helical flutes capture exiting gasses for improved final burn and significant reduction in muzzle flash.
