maybe they should have a disclaimer about working on certain parts. i wonder what kind of jigs they are using. a padded vise and wood clamps would be a no brainer. i dont think the bolster was welded in but who knows. the dimples are deep and small almost plier like but i cant figure out why the barrel had these scrape marks inside the barrel and the worn blueing. on the invoice it says they cleaned it. maybe its standard practice but it was clean when i shipped it. not what im use to as far as service goes in comparison to thompson center. they would replace parts or hot blue the gun and it would look brand new for no charge. im not looking for a freebie but i didnt want the gun roughed up either.i went through a similar problem with magana port with a shot gun. if they would just say up front that barrel damage may occur at least you know what your getting into. if i was the gunsmith on that job i would be embarrassed. at least they could have touched up the blueing. im thinkinh they had to heat the barrel in that area to loose blueing like that.
