I have a hi-lux (aim sport) 2-7x42 long eye relief scope on an enfield, forward mounted so that the back of the optic is about flush with the opening to the action, I read about these scopes on a few other threads and decided to give it a go, it is the right mag range and size for that rifle as a bush gun.
I would go with something this size but made by a more reputable manufacturer, the scope mentioned suits that rifle very well and I think it would do well on an SBL. Also it is a 30mm tube, I have a forward mounted picatinny rail and used UTG quick release rings. The scope is very functional shifted slightly rearwards as well, long eye box.
