I have been a shooter and reloader for some years now but never bothered much with airguns. Well, a while back I went to buy a cheap Industry B-2 springer for my buddy's son's birthday and found out that with a little bit of work (tightened the slot which the barrel fit into and glassed bedded the stock), the thing actually shot into 3/4 inch from 10m with a rotten 14lbs trigger, bad sight and all. That was then I decided to start shooting airguns as well (it is cool not having to spend hours to relaod ammo and pick up cases). Seeing that I am new, can any one tell me how often must I lube the spring/pistol and just how long would the seals last? What kinda maintenance do I need and how long would a spinger last?
