The Kak Industry A2 Extended Flash Hider is purpose-built for shooters working with short-barrel rifle builds who need a legal-length solution without sacrificing flash control. Threading at 1/2x28, this extended A2-pattern flash hider adds length to your barrel while maintaining the proven A2 design—a practical way to bring a 14.5\" barrel to just over 16" when pin-and-welded. If you're assembling an SBR-adjacent build or simply want authentic A2 flash suppression on a mid-length system, this hider delivers the classic performance in an extended format.
Constructed from milled steel with heat-treated phosphate coating, this flash hider is built to handle repeated shooting sessions and the demands of hard use. The pre-drilled hole simplifies the pin-and-weld process, a common step for shooters who want their muzzle device permanently attached and legally compliant. The extended profile gives you the flexibility to meet overall length requirements while keeping your barrel shorter—a real advantage in modern tactical and hunting builds where compact handling matters.
This is no-frills, straightforward muzzle hardware: you get the hider itself, ready to thread on and secure. A crush washer isn't included, so factor that into your build if you need one. Whether you're configuring a precision rifle, a defensive carbine, or a hunting platform, the Kak A2 Extended offers reliable flash mitigation in a format that solves a real problem for short-barrel builds.

Frequently Asked Questions
Will this flash hider work on my AR-15 or similar rifle?
Yes, if your barrel has a 1/2x28 thread pitch. This is the standard thread pattern for most modern sporting rifle barrels in 5.56 NATO and similar calibers.
How much length does this add to a short barrel?
The extended A2 hider measures 2.060\" overall, so it will bring a 14.5\" barrel to just over 16" when pin-and-welded—a common solution for meeting legal length requirements.
Is a crush washer included?
No. The crush washer is sold separately, so you'll need to source one separately if required for your build.
Can I install this myself, or does it need a gunsmith?
The hider has a pre-drilled hole for pin-and-weld installation. Pin-and-welding typically requires a gunsmith to ensure proper alignment and permanent attachment.
