I bought Romanian AK-47 kit and  AK-47 AKM Barrel 7.62x39 Nitride Coated 7.62x39mm from CenterFire Systems. My question is with the gas block. My gas block just slips on with out any force.My gas block slides onto the barrel like an old hooker. I can spin it around completely with my hand.Is this a out of spec barrel? Attached File

Put some blue locktite on it and torque it down
Should be good

Not sure if you're serious, but that's terrible advice.

I kinda figured he might be facetious in that statement. Lol

I would mic the bbl and the ID on the gas block. Someone may have reamed the gas block in the past. If so they are pretty cheap to replace or if you are wanting to keep it all matching once it is pinned on it will be fine however getting it to stay in place will be a challenge when drilling. You can use a C - clamp and padding or take some pipe and make one the exact length from gas black to rear sight and then one from front of gas block to threaded part and cinch down to hold in place.
