I had picked up a project rifle at the local gun shop. It had been ridden hard and put way wet. It is an Interarms MkX Mauser chambered in 7mag. I refinished the stock and floated the barrel. I also added a Timney trigger as the one on it didn't meet my standards. There was some pitting on the barrel and other areas where the bluing was thin. As I cleaned and buffed the bad spots I noticed the barrel was made by PO Ackley Inc. I never knew he had a barrel company. I can only assume the quality of the barrel from the way it shot. What can you tell me about this rifle/barrel combo?
