STG58 kit gun. I have always had problems sighting it in and just learned to shoot aiming to one side. I gave it to the gunsmith last year and just got it back and he showed me the barrel was bent somehow by looking at it with a perpendicular line. Anyway I am looking for a new barrel and a gunsmith to install it for me and I live in Raleigh NC. I would like to do local work and not have to ship it off to get it fixed. Arizona Response systems put it together for me about 12 years ago and I will call them to ask what I can do about it. It has seen a few rounds since then and always reliable. Just shoots off to the right too much. Any help is appreciated. Thanks.
