Description
The A2 flash hider has earned its place as the default muzzle device on just about every AR platform for one simple reason: it works. Noveske's take on this classic keeps everything you want from the original design and pairs it with the build quality the brand is known for. This version is threaded 5/8×24, which makes it the right fit for AR-10 and .308 Winchester / 7.62×51 barrels.
The job of any A2 is to redirect the burning gases that leave your muzzle so they don't bloom into a bright flash in front of your eyes. That matters most in low light, where a big muzzle flash can wash out your vision and cost you a follow-up shot. The classic slotted A2 profile vents those gases up and to the sides, cutting down the visible flash and helping you stay on target through the string.
Why the Noveske A2 Flash Hider Still Gets the Nod
There's a reason this design has stuck around for decades. It's proven, it's tough, and it doesn't ask much of you. Machined from steel and wearing a matte black finish for corrosion resistance, this is a muzzle device you can bolt on and forget about. No fragile tines, no finicky timing windows, just a workhorse that holds up to heat and round counts.
Setting Up Your AR-10 A2 Flash Hider
Installation is straightforward for anyone comfortable turning a wrench on their rifle. The flash hider ships with a 5/8 crush washer, so you have what you need to index it and torque it down in one go. Thread it onto a bare 5/8×24 muzzle, snug it with the crush washer, and you're squared away. It's a smart pick for a fresh .308 build or as a replacement for a worn or lost device, and it pairs cleanly with the rest of a serious AR-10 setup.

Frequently Asked Questions
What rifles does the Noveske A2 flash hider fit?
This one is threaded 5/8×24, which is the standard muzzle thread for AR-10 pattern rifles and .308 Winchester / 7.62×51 NATO barrels. Make sure your barrel is cut for 5/8×24 before ordering. If your muzzle is 1/2×28, that is the smaller AR-15 thread and you would want the 5.56 version instead.
Does the Noveske A2 flash hider come with a crush washer?
Yes. It ships with a 5/8 crush washer, so you have everything you need to index and torque it down without a separate trip to the parts bin. Just thread it on, time it with the washer, and tighten.
What is this flash hider made of and how is it finished?
It is machined from steel and wears a matte black finish that helps it stand up to corrosion and the heat of regular shooting. Steel is the right material for a muzzle device since it takes the repeated thermal cycling without issue.
What does an A2 flash hider actually do?
It vents the burning gases leaving your muzzle up and to the sides, which breaks up and reduces the visible flash. That is a big help in low light, where a bright flash can wash out your vision between shots. The classic A2 design has been proven on the AR platform for decades.
