I have a GA Precision rifle and just noticed that the entire action was loose. I went ahead and removed the action from the stock and there is quite a bit of dirt and grass in there. I have recently taken a 6 day class at Rifles Only so it got a small work out. I am wondering how to clean this weapon correctly and thoroughly without gumming things up, or using a cleaner that would mess something up. I normally use rem oil all over with a nylon brush and a barrel snake. I don't normally take the entire action out so what do I do with the trigger mech. ? What kind of cleaner can I put on inside of stock? Any advice?
