First off I already have a compressor.... Scba tanks...Aqua Environment External regulator... I have property here in Pennsylvania I'd like to small game hunt....Our regulations are .177 and .22 cal airgun s only.... Sucks a lil....I'm limited on funds but hate to miss another small game season. I can buy a refurbished Umarex Origin 22 cal for $206.00 on EBay... I'm Also considering Airforce outlet page ...seconds on a Airforce Condor 22 cal....probably 24 inch version... $500.00 and some change... I assume barrels on both will be rough...I'm experienced in hand lapping bore with lead laps...I'm familiar with Airforce platform.... Have tethering set-up..... Origin has a stock.... Probably not hold.sensitive..... I know my Umarex Airsaber much less hold sensitive and easier to shoot than my Texan....Weight is a concern... I'm semi handicap.. Any thoughts of you who.are 22 cal small game hunters chime in...I'm also.setup up.for.casting ... So id like to cast for either choice in the future... I'm willing to modify and upgrade for performance if cost effective..... Thanks friends
