CMMG A2 Flash Hider 1/2"-28 Thread for AR-15 5.56/.223 Matte Finish

The CMMG A2 Flash hider for AR-15 rifles in 5.56/.223 is a straightforward, mil-spec muzzle device built for shooters who want classic AR aesthetics and reliable performance. This steel-constructed hider threads onto any AR-15 barrel with a 1/2"-28 pitch — the standard threading for 5.56 and .223 uppers — and delivers the look and function of the original A2 design that's proven itself on ranges and in the field for decades. If you're assembling an upper receiver or swapping muzzle devices, a traditional A2 hider anchors the front end with no-nonsense functionality.

Steel construction means durability through countless rounds and cleaning cycles, and the matte finish resists glare without drawing attention. This isn't a fancy compensator or brake; it's the baseline — which is exactly why it works so well for standardized builds, legal compliance in restricted areas, and shooters who prefer simplicity over flash reduction hype.

Whether you're completing a mil-spec build, replacing a damaged device, or just want the classic AR-15 look, CMMG's A2 flash hider threads on securely and stays put. Check your barrel's thread pitch before ordering — 1/2"-28 is standard for 5.56, but some barrels vary.

Frequently Asked Questions

Will this A2 flash hider fit my AR-15 barrel?

Yes, if your barrel has a 1/2"-28 threaded muzzle. This is the standard thread pitch for 5.56 and .223 AR-15 uppers. If your barrel uses a different pitch (such as 5/8"-24), this hider will not fit. Check your barrel specs or feel the threading before ordering.

What's the difference between a flash hider and a compensator?

An A2 flash hider is a basic muzzle device designed with the original mil-spec AR profile. It provides minimal recoil management compared to dedicated compensators or brakes. It's valued for its classic look, reliability, and legal status in states with muzzle device restrictions.

Is this steel hider legal in restricted states?

Laws vary significantly by state and municipality. Some areas restrict flash hiders or compensators under assault weapons regulations. Check your local and state laws before purchase — we can't advise on legal status, but CMMG's traditional A2 design is often a safer choice in restricted jurisdictions than modern brakes.
