I inherited my dad's old Winchester 94 from my dad and I'm sure it has not been shot in about 20 years. Should I take it to a gun shop and have them look at it? or would that not be necessary? I do all my own basic maintenance on all my guns, but I don't have experience in lever actions. Are there springs that I need to replace? or should I just lube it up and take it to the range? Any advice would be greatly appreciated.
