The Radical Firearms Zero Impulse Muzzle Brake features a highly effective, patent pending three chamber design that redirects high pressure gasses. This significantly reduces both felt recoil and muzzle rise, aiding the shooter in staying on target even during full auto fire. The rear-angled side ports with generous top ports are exceptionally effective, allowing for faster follow-ups and dramatically reducing the effort required to stay on target. Machined from a solid piece of 4150 chrome moly steel and finished with an exceptionally corrosion resistant salt bath Nitride, this AR-15 muzzle device is highly durable as well!

Great for recoil reduction!


Awesome recoil reduction but also added some blowback i could feel on my face. Also was much louder than others i have used. If reducing recoil is your ultimate goal. get this!!

An excellent muzzle brake

by -

Recently bought the NADA brake to replace the flash hider on my Ruger AR556. The unit screwed on 1/2x28 by hand until the brake contacted the crush washer. It needed about 120 degrees to clock. A 6 inch long Crescent wrench was plenty to turn the brake. I oiled the threads sparingly.
<br>Had a chance to shoot it briefly and also watch it being fired. Recoil seemed about 90% reduction and muzzle movement was barely perceptible. Hearing and eye protection is required for any shooting so it isn't an issue. I recommend this brake, especially on an AR handgun

Great products from Radical Firearms

Radical firearms is an awesome company and make great products. This zero impulse muzzle break works as described it reduces recoil and barrel lift. For someone who never used a product like this you will feel more pressure to the sides but the reward is worth it.

First times a charm

Bought this for my 10.5” Pistol chambered in 5.56... Love the concussion it gave. Then I build another 10.5” Pistol chambered in 7.62x39. Now I have TWINSIES..

Not a good buy

by -

Couldn't even thread it on by hand with my RRA anD Ballistic Advantage barrel. Hard to line up the threads and when I did couldn't get one full rotation! Something's out of spec! My VG6 threads on just fine!

Good & bad!

Very good at reducing muzzle climb and felt recoil also it’s a great looking brake but I can’t stand and don’t wanna get used to the blowback, you get shot in the face with air every pull of the trigger and that can be very annoying and disturbing. That’s why I only give it ⭐️⭐️⭐️!

Impressed for the price!

I bought this brake on sale and had very low expectations.
<br>No threading or clocking issues, decent finish and no burrs. Reduce recoil worked better than expected, blowback was minimal compared to the more expensive brakes. Have not tested with rapid-fire though.

Works just fine on my 556 does what it is meant to do reduce recoil and muzzle rise.

Great results and a great price.

Was very pleased with the product received and especially the price. Brale installed on the rifle nicely and fit tightly when clocked to correct position. No issues threading the brake onto the barrel, threads lined up very nicely and were hand tightened until it hit the crush washer. Does have some heavy concussion to shooters standing beside you, but that is how it's designed to work. Recoil was above expectations. If it comes back in stock at this price, I will purchase several just to have for future builds.

Solid budget brake

My ar didn't come with a brake and it was hard to see where my shot was even going when shooting outdoors. Night and day difference after installing. With sale price this is a no brainer.
