Here is a very light weight custom Discovery .20 cal carbine I built years ago. Probably $400 in just the parts. I shortened the airtube, built a full shroud and custom barrel band, machined a skinny plain steel L/W barrel, JR steel breech, and plastic stock . The tune gives a 22 fpe bell curve for 12 shots with ES under 15 fps on a 2100 psi fill. It hangs on a nail in the barn for years and is always first shot spot on every time I grab it for pesting. I live in the NC mountains, a humid environment that is prone to periodic heavy fog (clouds) that turns everything wet with condensation. I guess the lead coating in the bore protects the non-SS bbl because the bore scope shows no rust. The stars aligned on this build because accuracy is astounding, POI never changes, and I hardly ever miss with this one. Not very pretty, but a keeper I will never sell.
Waited...but just gotta ask...WHY?
Rifle without a shooter attached is just an expensive stick....as far as shooting stuff, one can't do "jack" without the other...so why kick the airgun out to live in the yard.
WHY PCP"...if anything they'd be the more likely to shoot/shoot again to the original specs with the same external /finish damage.
Sorry, but I'd rather leave my wife outside than any of my guns! 🙂
Even a dog, cat, or chicken gets some kind of roof over it's head...just pound it into the ground like a tent stake if that's a goal,but not real sure what that would tell you.
HAve been outside with the rifle over night many times.....it didn't get anything happen to it that didn't also happen to me. ONce we were done,brought the rifle and myself back inside and took care of whatever rain/cold/dew/frost/dirt happened to either of us.
