    A 1 Joule spring should bring you up a bit to over 300fps at the very least. If you're looking for better range and accuracy though, a decent hopup rubber like the Guarder clear one can help just as much (if not more) than extra fps.

    A nozzle and tightbore barrel will also impreve FPS and accuracy.

    the hop rubber, guarder tight bore nozzle, and tight bore barrel would give a great boost to performance and you can keep the fairly soft stock spring running

    A one joule spring would be perfectly fine in your marui. You could do the tightbore, hop up ect as well. Also if your going into the box you may as well do the bushings.
