    I'm looking to buy a p90. I want to upgrade the fps so it can be used as an assault rifle. I need to know what the best way to do this is. I'll probably get a Classic Army sportsline.

    First of all, don't get a classic army sportline. They are know for being bad guns. Second of all, most p90s come shooting pretty hot so you won't need to upgrade the fps. I'd recomend a ks p90. It is very cheap and can be upgraded. If you really need high fps for some reason, you'd probably want to upgrade the spring. Also, do some seal and compression mods.

    If you want to talk to someone about the KS P90 then pm alex, that man will tell you everything you need to know about it.

    Edit: Speaking of the devil there he is.

    AEG basic tuning...

    adjust AOE
    clean, re-shim, re-lube
    test compression and upgrade leaky parts (bucking, nozzle, piston o-ring, cylinder head sealing)

    KS p90 requires new bushings, tappet plate, nozzle and piston. it's a good base p90 to upgrade.
    add an rhop and expect easy 200-250 feet range
