I have a mk18 with a gen 1 wolverine inferno. Only been fielded about 2 times. Body is a G&g. Standard green bucking and barrel. Has a amped airsoft line that plugs into the engine. Can include some attachments. Can include tank 2 lines and a reg for 100 more. Will be open for offers but will be kind of picky. Looking for arp9 and cash mostly. And tm recoil shock Only problem is that when you plug in the battery it goes into programming mode. So it's a trigger problem (I put it in wrong) so it is like a 5 min job and it's fixed.
