+1 on the KC-02
those things r beasts, ive had mine for a few weeks and have gamed it quite a bit and i have to say the simplicity of it is extraordinary and the power per dollar is unparalleled.
when i start playing outdoors i would definitely look at a tightbore and/or the hopup.
Sweetest part about this gun is the ability to change its role quickly.
Slap on a stubby grip and run 30 round mags and you have yourself a real good assault kit.
Get a nice scope with a hopup and a Tight Bore and you have yourself a DMR.
Full auto kit with duct taped 30 round mags and you have yourself a support weapon
