Are there any muzzle brakes that also serve as flash suppressors? If so, which do you recommend for 7.62x39?

If not, would choose muzzle brake or a flash suppressor? IIRC, muzzle brakes increase the noise level. Is that correct or am I mistaken?
 
I don't know. But I do know that the government tried to combine both functions into a single attachment for the M1/M2 carbine, and gave up. Redirecting muzzle blast to tame recoil reduced effectiveness of any "flash hider", so the goals seem somewhat at odds.

Levang Linear Compensator

I put one of these on my AR. It's supposed to help with recoil, but it's a .223 so there isn't much to begin with. What I like about it is that it directs the noise out the front so it is much more pleasant to shoot.

For an AK, finding a true flash suppressor that also brakes will be a challenge. After trying several, I finally settled on the AK 74 type brake. Probably does little to reduce flash, but it looks great & the gun groups well with it. Recoil is near zero even from the bench, but I also have an Aimpoint 9L on an Ultimak that adds a lot of weight up front.
 
do a search on the FSC 556

they do make a 308 version

Yes there are devices that both mask flash, and reduce recoil. They also have the added benefit of reducing noise as well. The down side is you will need to fill out some paperwork, pay a tax stamp and wait patiently for a few months before you can pick one up.

If guessed sound suppressor is the answer then congratulations.
 
What he said.

Flash suppressors work by breaking up the muzzle gas and cooling it.

Brakes work by using the high pressure muzzle gas and redirecting it.

They really do opposite things.

A can gets you both effects but at the cost of complexity, weight, bulk, and a $200 tax stamp.

In my experience the muzzle flash of most 7.62 x 39mm rifles is fairly minimal and is caused by unburnt or still burning powder at the muzzle. Solutions include longer barrel, suppressor, and a flash hider... but the cheapest option is to ignore it and don't shoot at night.
There are also compensators as well as muzzle brakes to consider too.

The angled some call spoon shape attachment for the AKM is a compensator and is designed to angle the muzzle blast upwards and to the right.
The purpose is to direct the muzzle downwards and to the left.
Firing from your right shoulder because the barrel line is above your shoulder the rifle will kick upwards during firing.
Rifles with in line barrels (that is in line with the stock) like the SLR, M16 and FG-42 just tend to push straight back rather than kick upwards.
Because the rifle is against your right shoulder recoil pushing back tends to turn your body so combined the forces move the muzzle up and to the right hense the compensator compensates for the effects of recoil for a right handed shooter.
A muzzle brake redirects the gas propelling the bullet to reduce felt recoil.

With a 7.62 x 39mm rifle you should be wearing hearing protection so the added noise of a muzzle brake shouldn't be an issue.

I own the AKM and the AK-74 type muzzle brakes and I also have an AKS-74U muzzle brake too but my preferred muzzle device is a suppressor.
 
IIRC, muzzle brakes increase the noise level. Is that correct or am I mistaken?
That is correct, and the reason that none of my rifles have a brake. I find that they are intolerably loud (increase sound by 5+ dB or 150% or greater). OTOH I have several flash suppressors. The folks above that said a sound moderator (suppressor) is the best solution are correct, but that requires a significant investment in the device itself (unless you construct your own) as well as the required paperwork (whether you build your own or not).

Just to avoid any confusion, building your own sound suppressor still requires BATFE approval and a $200 tax stamp, prior to construction.

I'm sure Maverick knows this but I wouldn't want anyone to get the wrong idea.

My 2 cents: a 16" or longer 7.62x39 does not require any flash suppression. I would use an AK-74 type brake if it suits your fancy, or one of the PWS options if you want something high end (I believe they make an FSC-AK that is threaded 14x1 for AKM type muzzle threads; or get an FSC-30 if you have a western rifle with 5/8x24 threads).
 
I live in a ban state where flash hiders are evil but something like the PWS, which offers some flash suppression, is legal. I've been extremely pleased and I think the sound complaints are overblown. They make an AK-version as well.

Yep, I went ahead and threw in a clarifying statement just to make it sure it isn't misunderstood.

The Bulgy 'soup can' was designed as a muzzle booster to increase back pressure on Krinks. I doubt it has any utility as a flash supressor.

On a Draco it may actually have some use as the gas port is very close to the muzzle, which reduces the time gas can act on the piston.

I can't stand muzzle breaks or ported barrels. Shoot next to someone with a muzzle break or porting on their rifle, it is utterly OBNOXIOUS. Some idiot had a ported barrel on his .338, the last time I was at the range and I flinched at every shot he took with that stupid rifle.

Like Brian I believe the Krink device might be of some utility on a Draco, but it will afford little flash suppression. OTOH the phantom is one of my favorite flash suppression muzzle devices; it works as well or better than any other I have tried.

S&W .300 Magnum with muzzle brake!

The question about noise!

I had a S&W .300 Mag and it had a factory porting style muzzle brake on it. It was so loud you could hear it a state away.

That alone made me hate it! Loved the gun..hated the brake! But it was a hunting trip that done it for me and muzzle brakes.

Late evening-low light, sun going down, deer on horizon....awesome right? Firing this shot was a kin to looking at the sun through a nikon scope!:fire:

I cut 1-1/2" off the barrel the next day and recrowned the barrel. I can say for sure that the felt recoil did noticeably change but my shoulder can take it my eyes and ears could not.:cool:
 
A very short AK 74.

Ahhh, you mean an AKS-74U?

Why is it called a Krinkov... I put that through a Russian/English translator and it doesn't even mean anything is Russian.

Late evening-low light, sun going down, deer on horizon....awesome right? Firing this shot was a kin to looking at the sun through a nikon scope!

Firing at targets on the horizon is very dangerous, even if you hit the target a round could still travel right through and you really have no idea what is behind it.
I agree it would look very impressive, but to hunt safely I always consider where my bullets will end up... ie what is my backstop.

Regarding noise from muzzle brakes, they certainly make the weapon sound louder by redirecting the gas and therefore noise back towards the firer and those around them, but at the end of the day if the round is powerful enough to need a muzzle brake then you should be wearing hearing protection anyway.
A basic rule of thumb is that if the weapon has recoil so bad you find using it uncomfortable and you find yourself not wanting to fire it as much then think about a muzzle brake. If you shoot a lot at night especially with night vision gear then you might want a flash hider too. And if someone bowls up to the firing range with a 50 cal rifle and sets up right next to you then you can either move or politely ask him to pick another spot before he sets up.

Of course most of the weapons powerful enough to demand a muzzle brake use larger more expensive ammo so perhaps you'll save money by not fitting a muzzle brake.
Also enlarged pads for the rifle butt can also reduce felt recoil and spread the impact without redirecting the gas blast to make it noisy. Equally there are various bench shooting rigs you can buy to make shooting more comfortable too.

Depends on what sort of shooting you intend.
 
I ALWAYS wear my ears at the range. I heard the excessive noise upon leaving my vehicle when I arrived....set up on the opposite side of the 20 stall outdoor range. I was physically flinching with my ears on and at distance.....In my view they are abominations.
 
I once shot an entire Appleseed weekend with a Dreadnaught muzzle break on my AR. I just needed it to keep the gasses from making dust clouds when I shot. I showed up and one of the ROs was like

"Hey look! A 16" barrelled AR.....with a muzzle break."

He know why I had it, but he was also telling me that nobody was going to want to shoot next to me. I also told them that, but they kept laying down there for a while......

It worked well, though....then I went back to my A2 birdcage.
 
A friend of mine recently purchased a AK-74 that had a '74 style brake on it. He shot 20rds through it, and all I did was put my hands over my ears, and it was fine. I then shot 10rds through it with no problems what soever. If I was going to put a muzzle attachment on a '47, it would definitely be a muzzle brake. Allows for faster follow-up shots. IMHO :)
