Give your AR-15 the authentic look it deserves with the Retro 6-Inch Extended Flash Hider 1/2x28. Inspired by the iconic XM177 and other early retro builds, this muzzle device adds both style and function. Whether you’re completing a clone-correct rifle or simply want a unique barrel extension that stands out, this 6-inch flash hider combines vintage aesthetics with modern machining quality.

Why Choose a 6-Inch Extended Flash Hider?

The extended flash hider isn’t just about appearance—it’s about practicality. By adding length, this muzzle device allows you to bring shorter barrels to legal 16-inch compliance when pinned and welded. That means you can run a 14.5” or 10.5” setup and stay within regulations without sacrificing the retro look.

• Retro styling – Modeled after XM177 and early AR-15 muzzle devices.

• Pin & weld ready – Pre-drilled for straightforward installation.

• Standard 1/2x28 threading – Compatible with most AR-15 and 5.56/.223 barrels.

• Durable build – Heat-treated steel with a phosphate coating for longevity.

• Functional & authentic – Balances muzzle flash control with period-correct aesthetics.

Extended vs. Standard Flash Hiders

A standard A2 flash hider may work for a 16” barrel, but it won’t add the length needed for NFA compliance on shorter barrels. The Retro 6-Inch Extended Flash Hider provides both the extra length and the vintage style that AR builders and collectors demand. It’s the perfect combination of function and authenticity.

Who This Flash Hider Is For

• Retro enthusiasts building XM177 or Vietnam-era AR-15 clones.

• AR-15 owners needing to extend a 14.5” or 10.5” barrel to legal 16”.

• Shooters who want a muzzle device with both performance and personality.

• Collectors who value clone-correct parts with a historic look
