I received an old beat up Winchester model 190 semi-auto .22 a few years ago. It had been through some rough times as a ranch gun. When I got my hands on it the first thing I did was clean it. The bolt would stick open durring fire and the trigger group had a gritty feeling. I wanted to do something with it because it is pretty accurate considering the hell it has seen. My buddy and I took it down to the receiver and took apart the trigger group completely and even pulled the barrel to clean everything. Once it was done I thought I could bring it back. Does anyone know what all can be done or have any advice on how to do some refinnishing? Thanks
