If you’re running a 14.5” AR-15 barrel, you know the challenge: bringing it to a legal 16” overall length without sacrificing the classic A2 look. That’s where the A2 Extended Flash Hider 1/2x28 comes in. This extended muzzle device gives you the length you need while maintaining the trusted, time-tested A2 design that has served generations of shooters.

Why Choose the A2 Extended Flash Hider?

The A2 flash hider is one of the most recognizable and functional muzzle devices ever designed. Our extended version keeps everything shooters love about the A2—rugged durability, reliable flash reduction, and compatibility with 5.56 rifles—while adding extra length for pin and weld applications.

• Clone-correct A2 style – Classic design with extended length.

• Pin & weld ready – Pre-drilled for permanent attachment.

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

• Durable finish – Machined steel with a military-correct protective coating.

• Legal compliance – Bring your 14.5” barrel to over 16” for NFA requirements.

Extended vs. Standard A2 Flash Hider

The standard A2 flash hider is shorter and works well for rifles with 16”+ barrels, but it falls short for legal compliance on 14.5” builds. The extended A2 provides that extra bit of length without changing the traditional look or performance. This makes it the ideal choice for builders who want an authentic military-style rifle that also meets regulations.

Who This Flash Hider Is For

• AR-15 builders completing a 14.5” to 16” pin and weld project

• 5.56 NATO shooters who want a durable, reliable muzzle device

• Retro and clone enthusiasts who want the proper A2 profile

• Anyone seeking a cost-effective, mil-spec style muzzle device
