Ok, so I have researched this topic a lot more and I am confident that I can install a R-hop. I still have a question though regarding the actual operation of the r-hop. I think I am just being dumb here.
Once the r-hop is glued in placed, does it still require pressure from the nub, because once glued it is flush with the inside of the barrel (so how does it contact the bb to create backspin?)
I think I am missing something really obvious here
