AK 47 Muzzle Brakes – Demonstration / Test in HD (AK74,Slant,Nut)
AK 47 Muzzle Brakes – Demonstration / Test in HD (AK74,Slant,Nut)
Testing the differences in recoil and muzzle climb with no muzzle device, a TAPCO slant brake, and a TAPCO AK-74 style brake. I know I’m chicken-winging. You won’t be the first person to comment, so don’t bother. Shot at Arnold Rifle and Pistol Club, St. Louis, MO area, with a Canon 7D.
My CIA GP1975 came with a slant brake but before I got it I rented a CIA C39 with the TAPCO 74 brake on it. There is a HUGE difference between the slant and the 74 brake. Ordered mine today.
It is meant to be installed with the open cut facing UP and RIGHT, directing blast in that direction, pushing the muzzle DOWN and LEFT. If you watch high speed footage of an AK on full auto with the slant brake, it actually pushes the muzzle down and left a good ways with each shot, stringing left and down instead of up and right on the target, like most other full auto weapons would. All issued AKMs and AKMSs were set up exclusively for right-handed shooters.
Thank you very much for the explanation/clarification. Now I can proceed with the permanent installation of the slant brake on my Czech Vz.58.
This video just confirmed what I suspected, my slanted brake has more recoil than my slotted and 74 style tapco brakes, but the 1 o’clock blow out of the slanted brake seems to tune the barrel better giving me the tightest groupings than the other 2 brakes. Thanks, very good video.
This is a very common misconception. The slant brake was designed to counter the rotation of the bolt. Guns with non-rotating bolts will only climb up, not to the right. The right motion is created by the rotating bolt. Do some reading, try it out yourself, etc.
those are corrosive bullets by the way
their is also butt stalks that come with recoil removing enhancers
I like this, no bs straight to the point video. Detail but yet simple 😀 Love it!
I appreciate that. Is this because the angle of the slant brake is somehow "compensating" for the rotational bolt of the AK? The reason I ask is because I’m considering having a slant brake permanently attached to my Czech Vz.58 (which does not have a rotating bolt) Should the slant brake still be affixed angled slightly to the right? Or does this not apply due the different design of the Vz.58? Or does the rotating AK bolt have nothing at all to do with the subject?
There is a very small indentation on the bottom edge, which catches a bit of forward-moving ejcted gas and pulls the gun forward slightly.
Slant break all day!!!
Slant brake on AK 47 is good if you want a Bayonet option
I do like what you did but you were leaning into the rifle a LOT more on the AK74 break test. For those of us with a better mind it throws off the validity of the comparison. just saying…
Break or no break will work the same on a semi auto rifle. The break is only to help climb on a full auto gun. People are stupid ,breaks are srupid for semi auto rifles
who the hell buys brass case 7.62×39
He is chicken winging the gun.
Cool video. My WASR 10/63 came with the AK74 style. I got the slant break for attaching the bayonet and just to have a choice
Damn! I took off the brake on my ak74 and couldn’t find it now.
Super thanks to you for making a great, short, steady camera, to the point video.
All the yap, yap. First test. Forget it. The second test, rise greatly reduced but pushed him back, The third regardless if it is a copy did the best overall. It had a slight bit of first and seconds faults but gave better ability to control each. Just me saying.
Interesting. I didn’t realize that. However, that explains why I’ve seen a lot of pics where the slant brake appears rotated slightly that way. I really appreciate you telling me this as I’m about to have a slant brake permanently attached to my much loved Czech Vz.58.
Thanks…real time saver.
Nice vid and very informative.
Thank you sir
Oh, but wait a minute…the Vz.58 doesn’t have a rotational bolt. Hmmmmm?
The TAPCO "74 style" is not the same as a real AK-74 brake, as it doesn’t have the same expansion chamber and is really only a 74 brake in looks only. Arsenal has a genuine copy of the 74 brake which works much better.
After reading what I just said, I’d bet that realistically, it’s very much a combination of both. You are correct in that the shoulder will create a rightward movement. I’m just passing on what I’ve read on the topic and my own experiences. Maybe it’s time for another video?
not so cheapo anymore lol paid 775$ for 1 2 weeks ago
People spend $100 on a muzzle break but it looks like the slant break is better than the ak74 style.
I would have like to see u do the same test only shooting one shot at a time. I have not seen anyone do a muzzle break test using a 3 round burst, it was really kool thank u. Loved the slow motion replay!
Stootingect the Tapco AK-74 style muzzle is a bit heaver then the slant style, that in itself will keep the muzzle from raising. Just ordered one from MidwayUSA today. Thanks for doing the test.
The Tapco 74 style brake is not even close to an actual AK74 brake. The tapco is just a chunk of steel with a few ports at the end while a true 74 brake has an expansion chamber at the base. They are only the same on the outside.
great vid, thanks for sharing!
Ah yes- straight is probably correct for your application there.
Good deal. Thanks for your help! Great video.
I ow a type 56 and would like to hear from other gun enthusiasts what advantages do Russian aks have compared to their Chinese counter parts.
The rotating bolt has absolutely nothing to do with it. The slant brake is designed to cancel out the body’s natural movement under recoil. The recoil pushes your firing shoulder backward, while your support shoulder stays in place. This causes it to come up, and to the right, if you’re a right handed shooter. The slant brake pushes down and to the left to counter it.
is it just me or did the slant look the best?
Good demo buddy thanks..
my tapco slotted brake works better then both of them. I guess im 1 of the lucky ones that got a good 1 before they discontinued them. Good video
Hey I know this vid is almost 10 years old but I appreciate your upload regardless. Decided I will installing one of these on my AK, thanks for the vid!
Right- if it’s on pointed 100% straight, it’s not correct. Sounds good, make sure they weld it the right way!
The slant brake in general increases recoil
Having personally fired many, many firearms with rotating bolts, and several without (bolt action surplus rifles, SKSs, submachine guns with block bolts), I can tell you that a rotating bolt is not going to torque the weapon around its horizontal axis. There simply is not enough mass in the bolt compared to the remainder of the rifle, and the bolt is generally balanced around its center line. The only way a rotating bolt would generate torque would be a severe imbalance, like that of a flywheel.
The tapco 74 style does do a pretty good job, in my experience its not worth the huge change of point of impact about 6" left and about 10" down at 100 yards and groups sized opened up larger by about 2". Not to mention its not worth the huge amount of weight it puts on the muzzle almost 6 ounces. The slant brake actually does a great job at muzzle rise and helps you keep rounds on target while shooting fast. If your worried about recoil too I suggest the tapco slot brake only weighs 2 ounces and does not change point of impact or accuracy.
