Mike is right, pump guns like PCPs should never be left empty.
DID NOT KNOW THAT! lol i always assumed the opposite. thanks.
by the way i got a scope on it last night, took two hours and two trips to wallmart (mostly because my friend and i have the combined intellegence of a good fence post) but i got it on. then i couldnt get it sited it, when i dialed the windage, the elevation changed and vise-versa. till i figured out i had put the scope on sideways.
anyway, got it workin now, gunna see what the limits for range, ect are on it tonight. and i will deffinetly be getting some of that silicon grease. thanks guys.
