WTS or trade Tippmann x7 Phenom w/ e-grip and extras

I have the tippmann x7 phenom with the e-grip, i also put on a carbine stock and a 50rnd tac cap (still have original "low profile" hopper). I've used it for a couple seasons and although i lost the battery cover, the marker is in premium condition.

I would like to get $325 for it, the lowest i can take is $300.. or for trade i would like both a decent pump paintball gun, and a decent quality airsoft aeg m4, or gbb pistol..

Also have a 68/4500 carbon fiber tank, needs a new valve? but its a cheap $10 dollar repair.. will sell the tank and a remote coil for $50 or trade for spare mags for the airsoft if you got em
