AK-74/AK-103 style muzzle brakes

Are they supposed to be loose? I have the retaining pin and everything on my new Arsenal SGL21 (so it's not twisting off of course), but the brake could turn at least another 1/4.

Not worried about it since nothing seems to be hitting it on exit, but just wondering. I've searched the net and haven't found too much on it.

Noob to AK's so forgive my ignorance.

Yes, it's supposed to be loose and have some wobble.

Don't worry, it'll carbon up pretty quickly and then you'll want to know why you can't get it off and it isn't wobbly anymore.

I figured it would be you that responded. You didn't disappoint.

Thanks man!
