Ok... I got a romanian AK-47 and i put about 400 rounds through. I did it in increments of the 30 rd mags. Id switch off between firing my AR and the AK. I just sold the gun and the guy who i sold it to told me that the barrel is a little warped to the right... So im just gonna give the guy his money back and grab the rifle. Ill probably just take it to a gun shop and see what they can do. But how much would it cost to replace the barrel? And what kind of barrel should i get? As well, would there be a way to maybe re-"warp" the barrel back into place or would i better off just replacing it? Thanks.
