$18 Muzzle Brake – From AR Pros

71ajitxJqJL._SL1200_

It just goes to show that often in this industry that price of an item can have little relevance to its function, AR Pros has an $18 Muzzle Brake available through Amazon.com. The company touts the brake as its “short competition” model “with upgraded features” (though I am not sure what those “upgraded” features could possibly be).

Sarcasm and witty prose aside, I am actually quite impressed with the brake relative to the price itself. Putting on my manufacturing hat, its a drop-dead simple piece of machining using either a life tooling lathe or two set-ups using traditional mills after a standard lathe. The milling is very basic (just through the bore with no intricate patterns using a standard size bit).

The result is something that is cost and function-effective. While the porting is straight to the side, the multiple chambers and surface area will ensure the brake is effective.

Mounting of the brake is via a jam-nut (note, not the standard crush-washer mount). Weight is 4.16 ounces (heavy, relatively speaking) with dimensions coming in just shy of most competition circuit rules. The brake is 2.24 inches long and .94″ diameter. The brake is finished in standard phosphate.

Retail is $18.99, but Amazon Prime customers can pick it up for the mentioned $18 ($17.99, technically).

    A nice accessory for a budget AR.

    It looks more like its blued or nitrided than just a regular phosphate finish.

    • JSmath

      I believe it is phosphate coated. Not all phosphate treatments are dull. I’ve got an fair assortment of phosphate-coated muzzle devices, jam nuts, crush washers, etc. that have varying amounts of luster.

      Got a particular pair of jamnuts that I was convinced were nitrided instead, took them to a machinist friend for appraisal and he said they were phosphated.

      • Twilight sparkle

        Zink doesn’t usually look like that, and the link says its blued. It looks a lot like ionbond though, considering the price point it could be made in China with the retailer not really knowing what it’s coated in.

  • USMC03Vet

    I thought Amazon banned the sale of muzzle devices….

    • JSmath

      Shush! I’m on there several times a month getting the things I want and need. D:

    • MR AWESOME

      So banning Second Amendment stuff is okay but gay wedding cakes is a ‘no no’. This generation sucks.

  • chris lynch

    For the life of me, I don’t understand why most muzzle devices are so damn expensive.

    • Riot

      To get mall ninjas
      Its the same as designer clothes

    • USMC03Vet

      Because STHF marketing that claims if you don’t over pay for everything, your rifle will explode, you’ll get the clap, and your corpse will be audited by the IRS.

        Best comment I have seen on the internet in the last 2 months.

      • Paul White

        This needs to put in as a footnote to all reviews of high end gear

    • Darkpr0

      Machining time, particularly CNC, is expensive. Good metal is also expensive. Both because they could make something for you, or they could use the exact same time and material to make car/airplane/machine/whatever parts that companies are willing to pay more for. So, if you want them to make stuff for you instead of other stuff, you need to be willing to pay more than the other guys. It’s not because the part is suddenly worth 100 dollars more, but because the time it takes to make it is worth so much.

      If you had your own lathe and milling machine you would be able to very affordably make your own bits. There’s no magic to it if you have the skills.

      • Mcameron

        you dont need “vundersteel 9000” to make a good muzzle break……at most you need a standard barrel steel……

        and true….machining time can be expensive……..but considering im seeing muzzle breaks going for what some match barrels are going for….im calling BS on the whole “materials + machining time” excuse…….

        even the most bedazzled muzzle breaks shouldnt take more than 10-15min on a CNC…….and im willing to bet most take less than 5mins……..

        • iksnilol

          I am not really that pedantic but for crying out loud, it is a “brake” and not a “break”.

          Once or twice is okay but thrice?? Goodness gracious.

    • JSmath

      Darkpr0 gives you the real answer. Metals and quality of machines used.

      Alternatively, you can buy lots of inexpensive ones made by decent machinists using decent metal; Available all over the interwebs. Kineti-tech makes some alright ones – but don’t go buying their comp for any non-US AKs.

      There’s also three or four companies selling inexpensive ones on Amazon. CNC Warrior sells there iirc, and they have their own sight. I like their brake on my VZ58.

  • tincankilla

    Looks a lot like the Miculek break, but with holes up top instead of having the vents wider up top.

  • mosinman

    i’m interested , if anything just to test out the difference in felt recoil vs the A2 flash hider

    • I have it. There is no muzzle rise. Recoil is average. Double my 10/22, I ‘d say.

      • mosinman

        thanks for your info!

  • Have it, love it. I am never at an official range, so my friends always stay straight behind me because this thing is obnoxious to anyone by your sides.

    Saw another amazon muzzle brake that had a blast diffuser around it. ( or whatever it is called.) No longer for sale due to amazon gun rules 🙁

  • 7n6

    These same guys sell a bunch of knock offs . They have clones of PA m4/72 , ALG single port , battlecomp , Griffin Armament comp , etc….. Not sure if airsoft or of material quality. Ships from HongKong.

  • JSmath

    Looking at those prices, it seems like the ALG single chamber brake is the rip-off. 😉

    • Twilight sparkle

      Not likely, you’re getting a known design from a respected company. This thing from amazon is a shot in the dark… which probably would blind you from the flash

      • iksnilol

        All brakes blind you.

        • rabrooks

          Not totally correct. The PRI-MSTN seems to flash only once or twice on each mag. tried it at night. That’s with Grn-Tips.
          There used to be a pretty decent comparison on youtube……
