I'll age your rifle for free...
Just let me borrow it for a few months and I'll treat it like I did my rifle back in the Marines... I'll promise to run with it through the woods, try not to bang it against too many trees, crawl through the mudd and shrubs with it. I'll take it out in the rain, sleet, snow and Virginia humidity. Shoot and clean it at least once a day so that lovely powder residue patina gets all over the brass and barrel. Dry it out real good next to a roaring fire when its cold outside. I bet I could make a rifle look used in a few months especially with winter comming.
