Muzzle Brake?
I'm looking to get a muzzle brake for my AK-47, which one would yall recommend. The barrel is not threaded.

What purpose does it serve? Is it a flash suppressor, of sorts? Does it act like a ported barrel, to reduce recoil? And, why are some adjustable> 0 -
It is not a flash suppressor, it actually makes things worse.
It is to reduce recoil. It redirects the gas coming out of the gun to do this.
There are some like the on the Browning (cant think of the name) that are used to "tune" the gun to shoot best.
I know the brake on my 300 Win Mag makes the gun kick like my .223 but will knock pop bottles off the table and the blast is huge.0 -

The brakes primary purpose is to reduce recoil. Some brakes/comps are designed to reduce flash signature. Generally most of them don't. Some are adjustable such as the Browning Boss system to tune the barrel harmonically to help tighten up groups.
Some brakes such as the "clam-shell" type are 'clocked-and-tuned'. This also helps with the torque jump of the bullet going through the barrel. On a right hand twist the brake will be turned top-center to about the 1100 position. This allowed my Armalite AR30 in 300 Win Mag to hold steady on a 300 yd. target when fired and watch the bullet hit. Recoil was so reduced I could fire the rifle holding it with just my thumb-tip behind the grip and my forefinger on the trigger.
edit:
I forgot to add that the muzzle blast caused by the break was horrendous. it would blow loose stuff off adjoining benches. I and some people shooting around me have come away with slight nose-bleeds from the blast cause by it. ...So there's a trade-off.0 -

"Muzzle Brake? What purpose does it serve?"
The original purpose of the muzzle brake is to divert the plasma or hot gases away from the base and sides of the bullet in order to minimize bullet upset.
"Is it a flash suppressor, of sorts?"
Not really. Muzzle flash is caused by super-heated gases or plasma escaping the muzzle from behind the bullet. Muzzle flash can be minimized by concentrating on balancing the load so that the gas begins to cool slightly while still in the barrel. Cooler plasma burn less bright.
"Does it act like a ported barrel, to reduce recoil?"
That depends on the design of the muzzle brake. If the side/top exit ports are angled correctly and the front exit is sized correctly, recoil can be reduced.
"And, why are some adjustable>"
Some are adjustable for timing the port location while others are adjustable for optimizing your load accuracy.

As explained in the previous posts a muzzle brake's primary purpose is to reduce recoil. Most folks complain about the excess noise and blast but I have them on 7mm Rem Mag, 300 Win Mag, and 300 RUM and frankly at the range I can't tell much difference in the reaction of other shooters than with my non-braked guns. I've warned people that I was about to touch of the 300 RUM and they said it was "no big deal." The brakes sure make a difference in recoil; the felt recoil of the 300 RUM is roughly equivalent to one of my '06s. One downside, in addition to the perceived blast issues, is they add barrel length. A 26 inch barrel with a four inch brake can be a little cumbersome to carry on a mountain hunt. 0
