Precision Rifle Blogs Muzzle Brake Testing

I, for one, enjoy Precision Rifle Blog’s truly data-driven approach to everything they do. Their latest drive into the data is an epic breakdown of .30 cal muzzle brakes, rating them by 4 major criteria:

  1. Recoil reduction
  2. Ability to Stay On Target (Muzzle Deflection)
  3. Sound
  4. Ground Signature & Muzzle Blast

Across four rifles, the details are incredible, with PRB taking time to measure things fairly and appropriately (I have rarely seen a sound test outside of suppressors where an actual SPL meter was used). The ground siganture test is rather novel to, using baking soda and high-speed photography.

Click the photo below to be taken to the article. Its focused on bolt-action rifles, but its easy to see certain designs and traits that seem to typify the best brakes.

    Love my JEC.

  • micmac80

    Surefire sucks so bad that even gucci tactical operators should take note.

    • Orion Quach

      Yeah maybe, but the brake wasn’t designed to be used much really. It’s an attachment point for their Q.D. silencers which is the key thing to take into account.

      • JSmath

        It’s more of a blast baffle than a muzzle brake. It just isn’t part of the suppressor.

  • Bear The Grizzly

    It’s interesting that what appears to be the best performers are brands I’ve never even heard of before. Perhaps proving that marketing is more important than results?

      That’s because you didn’t click on the link to read the article where he states that these are the most popular muzzle breaks in the “precision world”. Just because most of us on here are AR fans doesn’t mean there’s not another world outside AR’s 🙂 🙂 But I am with you on your thoughts. Who knew there were so many muzzle breaks out there…

      • Bear The Grizzly

        Thanks friend, I completely missed the link.

  • 6.5x55Swedish

    Is a big bar a good or bad thing here when it comes to sound?

    • micmac80

      Longer bar means quieter brake , all top recoil reducers suffered in that department

      • Grindstone50k

        If only there were other things that you could put on the end of the gun to make it quieter…

        • Dan

          We could call it a hush hush!

  • Blake

    Aren’t you guys friends with Andrew from Vuurwapen Blog? Did you somehow miss part 1 of his muzzle break tests? They’re incredibly data driven using an SPL meter and high speed cameras.

    • Giolli Joker

      Those were muzzle devices for AR15, these are for bigger calibers… I’d say that they’re both interesting, well done, studies that complement each other and are ultimately useful for us all.

  • Lance

    Bans over get a flash hider!!!

  • Dan

    I have limited hearing in my left ear thanks to the JP recoil eliminator. Friend handed his AR to his brother who without hesitation or warning went to town before i could get my muffs on. Felt like someone drove a pencil in my ear. Two shots and now everything is muffled and a loud ringing. The brake was amazing though especially on full auto.

  • Vitor Roma

    The JEC one installed on a MDR, it would be elegant.

  • Treyh007

    Good info but the VG6, Rainer Arms and PWS breaks would’ve made this research even better!

  • iksnilol

    Meh, I prefer silencers. They are unregulated where I live and they do a decent job of reducing recoil. Besides, what recoil the silencer doesn’t take care of, a good buttpad will.

    • Michel_T

      Must be nice…
      in my part of the world, the police will go after me if I don’t put a muffler on my motorcycle… and they’ll throw me in jail should I dare putting one on my rifle…

      • iksnilol

        It’s nice, but there’s some downsides as well. Minimum length is 33 inches. And shotguns can’t have more than 5 rounds or have detachable mags.

    Test needs a KAC MAMS
