7.62X39 muzzle brake on a 5.45X39 rifle?

[Kor]

Hey, all - I've been lusting after a particular, individual SAR-2 AK-type rifle in 5.45X39, and upon CLOSE examination I see that this gun has had a FA Enterprises "AK-74-style" muzzle-brake installed on it. Thing is, the hole in the brake is .30 caliber, not .22 caliber.

My question is, can I expect this brake to actually perform its intended function of reducing recoil, or will it actually do nothing but make the gun louder when I shoot it? Granted, the 5.45X39 caliber doesn't have all that much recoil to begin with, but if this brake isn't good for anything besides looking neat, and if I can't remove it to install a proper unit in its place, I'm probably gonna have to pass on it...

So, help me make the right decision, people!

well all a break will do is make the gun louder..a .30 hole problably will be a bit less on the ears. PS you really need a brake on a 5.45 best trade it for a 10/22 but its going to hop worse...

Because the hole facing downrange is much larger than the bore, the brake will deflect less gas than a 5.45-sized brake and so will offer less recoil reduction. However, the fact that less gas is deflected will also reduce the noise increase (theoretically). So maybe consider it "muzzle brake lite"?

I just saw the same 7.62 brake installed on a Hesse-modded 5.45X39 rifle, so I'm guessing it may be all right - but then again, if Hesse's using these brakes, it's gotta be because they're too cheap/lazy to put the correct brake on...

Krikes! Don't choose Hesse to emulate!
