Hello all, I have the above gun on my work bench that when fired the other day would let you push the trigger forward but would NOT set the trigger ....I now have the action off of the stock and I have found some corrision starting to set in around the stock and receiver ,I have cleaned this up,and cleaned the debris from the trigger assembly,but by pushing the trigger forward it will not set the trigger ,it's acting like a single stage trigger now.....I need a manual ! Thanks Jim
