I own a Royale 500 & Boss, .25 & .30 cal. respectively. Bought the Royale new from UA a couple summers ago & the Boss, used, a few months back. I'm putting on average 50 pellets a week through each hunting. Not much straight range time to speak of. Both guns are a dream accuracy wise, mechanically, quietness, etc. I'm finding so little info on gun maintenance for these in this forum & even on Ernest's Master Class vids. Have never had either one apart, done any adjusting, never done ANYTHING but load, shoot, lube & clean once in a while. Should I be doing something on a regular basis or "if it ain't broke, don't futz wit it"? They are so trouble & adjustment free & RELIABLE. Is that why there's so few posts or am I missing something? I just want to keep them in the best functioning condition possible. REALLY LOVE THESE & WOULD NOT SELL OR TRADE 'em, YET. Please advise, someone who knows. THANKS
