I picked up 3 tins of the new crosman a couple weeks ago that are made in spain to try out in my zobroi that shoots the us crosmans lights out at 980fps the new crosman shoot not quite as good as the old ones and the skirts have alot of flashing on them and not as clean as the old ones have to...
I think its like motorhead said , the valve should move freely through the hole easily and on mine the bottle valve oring was hard as a rock nothing to do with the popet valve leaking though just a leak point 😃
It’s funny how most the cases that come with expensive air guns are junk and can not use them if you have a scope on my fx m3 case has a big gap by the handle have not ever used it 👎🏼 the case with my mora is extremely nice 👍has all the cutouts and gun fits with a scope on😃
