I have a couple of different guns that were handed down to me and ones that I purchased and I need to know how to clean them. My collection includes but is not limited to a:lever action 30-30, bolt action 16 gauge, some older semi-auto pistols, some older revolvers, glock 23, colt 6920, mossberg 500, .22 semi-auto rifle. How do I clean these weapons? What do I need to buy to clean them and what do you use? Where can I watch videos on how to clean them? I have a free gun cleaning at Gander Mountain from when I bought my Mossberg JIC the other day. I think I might use it for my 30-30 because it's old and I tried sighting it in the other day and it wasn't working at all so I want somebody to look at it and tell me if the scope is broke or not. How much does it normally cost at Gander Mountain or somewhere else to get your gun cleaned?
