This is recap from our Video – Episode 3 Muzzle Devices (Part 1).
Recently we have tested first 6 AK muzzle devices in order to find the best one. Our non scientific test is based on 3 main events: so called “dark room test” to measure flash hiding capabilities; side pressure wave test to measure impact on operators in close proximity to the muzzle device and finally muzzle climb test, which was very subjective test based on quick shooting of 3 rounds on target. We have also collected all the data, like physical measurements, weight and prices to give you better whole picture of the subject. Below is our first Top 6 list. The winner of this competition will be put against another 5 muzzle devices in our future episodes.

I really appreciate your youtube channel and what you’re doing with the blog/website. Keep up the great work!
I love the all AK all the time aspect of AKOUL 47-74. After serving in the Marine Corps with an M16, all my personal weapons are AK based. I noticed that the PWS FSC47 wasn’t tested for this comparison though. I think you should look into it. I run those on all my guns and it makes the 7.62×39 shoot softer than a 556.
Hi Isaac does your fsc pull the pull to the side after each shot?
I had a JTAC and it reduced recoil but it pulled my barrel to the right after each shot
I really like the comparisons. Very informative. I’d really like to see a comparison with the FSC-47 as stated above as well as an AK Battlecomp and the Spikes’ Dynacomp. I’m looking for the best compromise of flash hiding and muzzle control I can get for an upcoming 308 AK variant build.
I have an SLR 107 CR w/ a Knock off Tapco compensater similar to the the one Arsenal uses on the SLR 107 FR. The barrel is threaded for a total distance of 1/2 an inch. I want to install the SRVV Jet Brake. How much of the barrel should be threaded? I want to keep overall length of the rifle to a minimum The CR has front site on gas block not on the end of the barrel
There is around 15mm of thread inside Jet Brake. Hope this helps.
do the DTK “bulgarian” flash hiders cause overgas issues in 5.45 aks?
Personally, i have not experience any problems when using DTK Bulgarian on my 74 clones…That’s all i can say about it. I’m not using this muzzle device now, because there are other, equally effective and lighter one available…
Rob, thank you for your thorough analysis. I plan primarily to hunt hogs at night with my 7.62×39 rifle, so no real issues with side blast. I would prefer to tame the recoil/muzzle climb to some extent, otherwise I would choose the Krebs Flash Hider. In 14×1 lh thread, what’s my best choice in a muzzle device?
Try to find Zenit DTK2
I just ordered a Jet break from circle 10 for 5.45x39mm, I have been using the standard chrome lined 74M break. Couple questions, does anyone use the Jet Break with corrosive surplus and how does it hold up? Also how does the Jet break compare to the Rifle Dynamics Venom break (the $200 one)?
You have to wash it after each use with corrosive ammo or rust will get on it quickly. As for comparing to RD Venom brake, i take Venom over SRVV.
First i would like to tell you that i am learnig a lot about the AK with your excellent videos… Now my question is.. I just recently bought a SAM7R-66 Ak (Bulgarian miled receiver)… Can i install a collapsible stock (AR-15 style) on this milled rifle?… Can you help me to find the parts that i need in order to do this?
Yes you can. There is company TDi Arms, they offer tube adapter for milled receivers, then you can add to it collapsible stock of your choice. It is going to look similar to this: https://www.facebook.com/AkOperatorsUnion/photos/pb.656164651082484.-2207520000.1417009636./881679048531042/?type=3&theater
hi rob ski, I have a question……..I have purchased and installed the jet brake on my Yugo m70 and I like that it has reduced recoil greatly! however it is short cycling now. any thoughts or cures for this…….thanks frank
Are you sure that this is happening because of the brake? If so, just get rid of the brake…your rifle may not have enough gas to cycle. Also, what ammo you were running on it?
No problems before brake installed…..was shooting silver bear and golden tiger. Shoots two rounds then short cycles on third also a slam fire occasionally thanks for the response, frank
Yugo AK’s have a longer section of threaded barrel than other AK’s. Maybe if it’s too far onto the threads it’s messing with the cycling in that way.
Have you ever tested the “flash can” type muzzle devices such as the one from universal or from kak. Thanks for your time and keep up the great work!
No yet…
I have a Saiga AK74 that came in with thecap welded onto threads and the anti Gunner hunting stock configuration. I have remedied the stock issues now looking to get barrel threaded and a break, any recommendations for a break and should I keep it standard AK LH thread?
It’s up to you man, if you want to stay within “AK family”, then get regular threads. Honestly, plenty of brakes to choose from…;-)
To me it seems the srvv made the rifle handle the best .
Hey Rob,
I just wanted to say great videos! I’m thoroughly enjoying watching (and rewatching) all the AKOU vids and reading the articles here. I just bought my first AK-47! I’m now looking at what muzzle device and I’ve come down to two options. Manticore Arms NightBrake vs Zenit DTK-2. Zenit gets some cool points but I’m having a hard time finding in depth reviews on it and it’s obviously much more expensive than the Manticore.
I was just wondering what your opinion on the DTK-2 was (sorry if you’ve reviewed it in a video that I haven’t yet watched) and if you think it’s better for recoil reduction/limiting muzzle rise than the NightBrake.
Thanks again.
DTK2 is awesome for recoil reduction – awesome. And not so awesome for using it with team…lol
Hahaha it’s a good thing I don’t have friends then. đŸ˜‰
Out of curiosity if you could have any two muzzle devices what would they be? Maybe I’ll order a DTK for recoil reduction and another that’s better in different ways. The Krebs custom maybe.
Thanks for your feedback!
The Venom Antidote is great for 7.62×39 but the Jet Brake is great for .308 Ak rifles. Why?
The SRVV is heavy which mitigates the recoil of .308 Winchester in a 16″ barrel. That weight absorbs recoil.
Two brakes for two calibers. I own both brakes. My SLR 101S uses the Venom Antidote while my Saiga .308 uses the SRVV Jet Brake.
Outstanding Web site and always great information. Please keep up the good work!
Hello Rob!

This: https://www.shop.akoperatorsunionlocal4774.com/Fighter-24-Muzzle-Brake-Fighter-24-Muzzle-Brake.htm
I know you like the Definitive Arms “Fighter” Break for AK74, but is it also your favorite selection for recoil reduction for a Saiga Sporter Rifle converted to AK47, 7.62 x 39mm?
If you are looking for pure recoil reduction, get this: https://www.shop.akoperatorsunionlocal4774.com/searchquick-submit.sc?keywords=bd2
I noticed all these are Left hand thread. Do you have a recommendation for a Right hand thread brake? Or an adapter to left hand thread?
Hi Rob, I have a KUSA k103 SF the muzzle brake is RH thread. What brake do you recommend?
Thanks for the info.
Check CNC warrior – they have huge selection in 24mmRH brakes
