    Hey all,

    Bought a GFC P90 last year and looking to upgrade it now but have no idea where to start. Hoping to improve my accuracy and FPS (currently between 260 and 290). Would prefer to upgrade as much as possible all at once rather then upgrade one part which results in another getting broken as a result and so on.

    Any help on suggested upgrades or who to talk to would be great.

    Thanks lads.

    Madbull Black Python tightbore with your choice of hop rubber should be the first port of call. I like the Guarder Silicon, but others swear by the Madbull Blue.
    The breakdown method of the P90 means this will be the easiest upgrade option by far. You'll have it done by yourself with no experience inside of five minutes.


    The rest goes internal. Upgraded wiring with an AB MOSFET to use 11.1V LiPo's (even larger packs fit perfectly in the battery space with no structural mods).
    Couple that with a good set of bearings and a good high speed motor (TM EG3000 or G&P M130 for example) and you'll have fantastic trigger response with a great rate of fire.
    If you don't mind extending the length a bit, a Madbull Quicksilver suppressor will make a huge difference to the amount if sound it produces. It really takes the majority of the high end snap out of it.

    That combination would make for a cracking performer.

    To upgrade the fps you would need to upgrade the spring. Or install a bearing spring guide and a bearing piston head. This will put your existing spring under more compression, thus increasing your fps by roughly 20. This is not an exact science, every spring will act differently, sometimes even from the same manufacturer. When it comes to tweaking fps, it is a case of trial and error. While you are not going to see much difference in performance between a 310 fps gun, and a 325 fps gun. There is a sense of accomplishment when you manage to nail that sweet spot.

    Also adjusting your AOE (Angle of engagement), will give you another few fps.

    You can see he has removed some of the teeth on his piston. This stops the gears catching, near the end of the cycle. It dosent have any adverse affects on performance.
