Inspired by the iconic XM-177 Moderator, the KAK Industry Retro Extended Flash Hider extends a 12.5″ barrel to legal non-NFA length when pin and welded. This 4-inch flash hider features 5 flash-hiding ports with a sealed bottom similar to an A2 flash hider design. Machined to Mil-Spec dimensions in the USA, this muzzle device delivers both authentic retro aesthetics and reliable performance for your AR-15 build.
CNC machined from bar steel, heat treated for strength, and phosphate coated to protect from corrosion, the AR15-XM177-FH-001 is built to withstand rigorous use. With 1/2-28 threading and a bore sized for use on both 5.56mm and 9mm barrels, this versatile device fits a wide range of AR platforms. The 4.15-inch overall length adds approximately 3.56 inches to barrel length when pinned and welded, and features a .125-inch hole pre-drilled for convenient pin and weld installation.
Ideal for AR15, M16A1, XM177, and other clone builds where period-correct style is essential, this flash hider completes retro builds with authenticity. Whether you’re building a Vietnam-era commando rifle or simply seeking genuine 1960s military inspiration, the high-quality phosphate finish and expert machining ensure your build looks and functions like an original.
