Helical Flutes Dissipate Gas, Hide Muzzle Flash Specially angled flutes hide nearly 100% muzzle flash, even during full-auto fire, by dissipating gas and retaining unburned powder for increased residual burn. Gas dissipation works particularly well on short barreled rifles, where large a large muzzle flash is common. The G6A3 is 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. Skirt extension conceals gap between barrel shoulder and flash hider on AR-15, M16, and M4 rifles. Grooved base ring allows integration of Blank Firing Attachment (BFA) used by law enforcement trainers, and permits installation of the Smith Enterprise M4DC CQB sound and flash suppressor (available factory direct to USG/LE and FMS customers). Helical grooves cut on the surface of the G6A3 allow for easy removal and installation of the M4DC suppressor.

Thread-on design requires no washer. Torque to 10 ft. lbs. maximum, self-tightens as weapon is fired. Use M-193, SS-109 (M855) and MK 262 service ammo for highest degree of flash suppression. Can be permanently attached to 14.5" long, M4 barrels for an overall length of 16.1".
