Most Helpful Positive Review Great Muzzle Device for the AK
Easy install for any 14-1LH barrel. Reduces muzzle recoil significantly. JMac Customs makes some of the finest quality items I have ever seen. I recommend this to anyone with an AK style rifle looking for extra performance!

Great Muzzle Brake!!

by Christian Hill, Verified Owner from SD, United States Written on November 28, 2024
Purchased for my Zastava to have a muzzle device on it as i dont plan on Suppressing it , it helped with recoil to a small extent as you cant expect drastic change from a muzzle device. The quality is also incredibly nice no sharp edges to get cut on and everything lines up , good price as well
Pros:
  • Quality
  • Function
Cons:
  • Loud

Flat like flat bread!

by Tommy, Verified Owner from NC, United States Written on March 31, 2024
JMac’s quality has always been top notch and if you’re looking for something that won’t break the bank but at the same time looking for something that is of quality, this is it. It shoots super flat and with the glossy finish, it gives it a pop. At least that’s how I like it. But definitely recommend it.

Muzzle brake review

by Joe, from AR, United States Written on November 21, 2022
The JMAC 4 port muzzle device is a sweet piece of kit for your rifle. Offers a great reduction of recoil and the machining and finish is top knotch. Easy install but not very popular at the range. This muzzle device is particularly loud.
Pros:
  • Recoil
Cons:
  • Volume
Would recommend: Yes

Excellent.

by TZ23, Verified Owner from IN, United States Written on September 29, 2022
This brake is the genuine article. Works wonders on my ZPAP. Greatly reduced muzzle rise and even flash...which makes zero sense to me, given how ridiculously firebally these sorts of muzzle devices usually are.

And somehow not much heavier than the slant brake. How? No idea.
Pros:
  • As Advertised, perfect fit and function.
Cons:
  • None
Would recommend: Yes
