http://www.wolfarmouries.co.uk/airsoft/bb/product.asp?page=product&id=GP857B this is the g&p one I was looking at, but like you say might just buy cheaper box to drop in and then service original box depending on which it is as I bought gun 2nd hand from a mate.

Hi, I've got an SRC 416D and I want to upgrade the gearbox, wolf armouries has g&p upgraded gearbox on their site for £99 would this be a good upgrade for my gun or is there anything better I could purchase?
