Gearbox's with interchangable springs

    To the people 'in the know' :)

    What brands etc. of aeg's/gearboxes are out there that allow for easy swapping of springs?

    After Berget this year I think that next time I need to up the FPS of my gun... I have it running lovely for Ireland at about 315-320, upgraded bearings etc., tightbore barrel, upgraded hop up, but still, at extended range, I was lobbing BB's at the enemy while theirs were ripping past me like angry hornets.

    I'd like something that makes it easier to change the spring once I hit another country, without having to completely disassemble the gearbox.

    Cheers

    A few options are open

    Systema ptw - nice but expensive, no tools needed
    ics m4 - the slit gearbox design allows for a budget ptw of sorts, only m4 at the moment mp5 split design on the way, no tools needed
    star/ares - easy change spring design along with nice externals m4 and g36 avaliable, some tools needed
    prowin ( and it's clones ) gearbox shells- replacement gearbox shell with ability to remove spring but a fair amount of disassembly

    Personally would go with ares or ics, both do use some unique parts but far less than the ptw and the unique parts are a lot cheaper they both still use standard batteries and mags, I would go with the ares/star for my ' If I could only have one' option. This is because the whole lower recover can be swapped put in seconds if you have a major gearbox melt down, all you need to do is keep a spare lower instead of a complete gearbox, and you have the quick change spring , great for travel

    just be shore to build your gearbox for the change in fps, not much point in a g&p m120 motor if you planning to jump up fps, you might as well invest in something like the m160 for example
