Description
The A2 birdcage is the muzzle device that put the AR platform on the map, and Noveske's take sticks to the formula that works. This is the standard-style flash hider found on countless M16, M4, and AR-15 rifles, machined to spec and cut for 1/2×28 threads so it drops onto the vast majority of 5.56 and .223 barrels without any fuss. The slotted, open-bottom design breaks up and disperses burning gases as they leave the muzzle, cutting down the visible flash that can wash out your sight picture in low light.
Why the Noveske A2 Flash Hider Earns Its Spot
There's a reason the A2 pattern has stuck around for decades. It's dependable, it's proven, and it doesn't ask much of your rifle. The closed bottom port helps keep muzzle climb in check by venting gas up and out instead of down, which means a little less dust kicked up off the ground when you're shooting prone. Noveske finishes this one in a mil-spec heavy phosphate coating, giving it solid corrosion resistance and that classic matte black look that blends right in with a factory barrel or a fresh build.
Fitment and Install on the Noveske A2
This flash hider is threaded 1/2×28, which is the standard pitch for 5.56 NATO and .223 Remington barrels. It fits M16, M4, and AR-15 platforms running that thread pitch. Best of all, Noveske includes a crush washer in the package, so you've got what you need to index the device and torque it down properly. For the cleanest fit, make sure your barrel threads are chamfered and clean before you spin it on.
Whether you're swapping out a tired old muzzle device, timing out a brand new upper, or just want a quality A2 from a name that's earned its reputation building hard-use rifles, this one gets the job done without overcomplicating things.

Frequently Asked Questions
What thread pitch does the Noveske A2 flash hider use?
It's cut for 1/2×28 threads, which is the standard pitch for 5.56 NATO and .223 Remington barrels. That makes it compatible with the vast majority of AR-15, M4, and M16 barrels on the market. Double-check your barrel's thread pitch before ordering if you're unsure.
Does this Noveske A2 flash hider come with a crush washer?
Yes, a 1/2×28 crush washer is included in the package. That lets you time the flash hider correctly and torque it down without having to source a washer separately. For the smoothest install, make sure your barrel threads are chamfered and clean first.
Will the A2 flash hider help with muzzle rise?
The A2 pattern has a closed bottom port that vents gas up and to the sides rather than straight down. This gives it a mild compensating effect that helps keep the muzzle flatter during rapid fire and cuts down on dust signature when shooting prone. Its main job is still reducing visible flash.
What finish is on the Noveske A2 flash hider?
Noveske finishes this one in a mil-spec heavy phosphate coating in black. It holds up well against corrosion and gives the device that classic matte look that matches a factory barrel or a mil-spec build. The steel construction stands up to the heat and pressure at the muzzle.
