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😃
Still waiting on mine to get shipped 😩 that is real good consistency and might get better the more you shoot it thanks for posting the groups keep it up 👍
Not done one on a r3 just my r5 and my friends r5 but there are vids on them not sure if edgun west has them or utube r5s are not that bad they are great guns the edguns👍
