I don't see how anyone can give you crap about shooting it in your yard unless you are careless..
Check your local laws. Some pissant jusrisdictions have a very broad definiton of firearms and some include items like "propelled by expanding gas" and some add "or other means." In some areas, even discharging a slingshot is illegal.
A couple of yeara ago I wanted to have my antique Feinwerkbau overhauled and I contacted Beeman, the orginal importers. They warned that disassembling one without the proper jigs and fixtures was pretty dangerous, since the compression spring contains a lot of energy even when "relaxed." Sort of like 400-day "anniversary" clock springs, which have injured a lot of amateurs who've disassembled them.
Send it to Benjamin and be done with it, and done with it right, with the proper seals, springs, etc. You can mail airguns with no problem, at least according to Postal Service regs.
That old Feinwerkbau (cal .177) is pretty powerful, and even puts substantial dents in my commercial pellet gun target box. I had to add more "backstoppageness" scrap carpeting in the back to prevent that. And as an added bonus it reduces the impact noise.
And the gun itself is not all that quiet in the first place --the spring noise is substantial, and if you oil it too much so that it "diesels," it yields a pretty loud crack.
