It would also help to know if anything is stamped on the barrel.

With the sights adjusted as far as they would go and 0.050 milled off the top of the front sight it shot 3 1/2 feet low at 100 yds. Doublestar said that they could not find anything wrong except it shot low and I should get different sights. I tried every combination I had at the house with no luck. I eventually had to do a custom front sight. My gunsmith had the same problem only it shot hard right. I don't know what he did to fix that guy's gun. Doublestar stopped returning my calls after I sent it in and it came back. It was about the time the run on guns started so they may have an excuse. I just got tired of waiting for them to fix it. It shoots good groups though.
