So today I finally got around to upgrading my TM M4 High Cycle. Added a 6.03 Madbull TBB. Was my first internal upgrade job. Initially was a bit scared of fiddling around inside but it was actually pretty easy apart from the annoying little nub which had to be maneovered into the hop up unit with a ball point pen. I don't have a chrono but instantly the gun felt like it shot with more of a crack and a more determined BB. Can't wait to skirmish with it tomorrow at Elite in Worthing, W. Sussex. It'll be my first woodland skirmish too! One last point - I went to Pro Airsoft Supplies in Highgate and the guys there were really nice and very helpful. Lots of customers hanging out in store like it was a proper gentlemen's club. Highly recommended.

Thanks for the tips guys! I have a Madbull Auto Tracer Blackside unit (which looks like a silencer). Will a long tightbore barrel fit inside that unit, or does it have to be a standard silencer?

So I have a Tokyo Marui High Cycle M4 and it's my first gun. Love it! I would now like to try my hand at upgrading it and see if I can increase the FPS a bit, to around 330. I was thinking of first getting a tightbore barrel, as supposedly that's the easiest way to increase FPS? Are there any other things that I could do to make this gun into a beast?
