woah there tiger!
hft.... butthooks....deep forend stocks I think we need some direction here or else you'll be wasting your time at work.
Rapid with a single shot tray in .177 will be fine, will it group at 45yds, it better had do or you have a sick rapid.
Your best with a sporter stock, the one you have is fine.
Scope, it will do, but there are better, budget £150 and you've got a scope that will do the business.
If you want a single scope to do both, get a bushnell 8-32 with a factory mildot...£400.
just shoot and enjoy!
