Buy on Ammo Depot

The KAK Retro Extended Flash Hider brings the classic XM-177 Moderator profile to modern AR-15 builds. Its 4.15-inch overall length extends a 12.5-inch barrel to legal non-NFA length when pin and welded, so the rifle stays compliant without losing the retro look.

Five flash hiding ports reduce visible muzzle flash, while the heat-treated phosphate finish adds corrosion resistance. Milled flats simplify installation, and the pre-drilled .125-inch hole is ready for pin and weld work. A crush washer is sold separately.
