modified g&g mod0

I have made some modifications to my G&G MOD0 airsoft gun. I replaced the hop-up unit with a Maxx CNC one, and installed a Prometheus tight bore barrel, R-hop patch, and smooth bucking. It shoots at a velocity of 320-330 fps using .20 bbs. I rewired it to the rear and swapped out the Magpul-inspired handguard for a full metal M-Lock one. It will come with several magazines, but some of them have feeding issues as they don’t sit flush in the magwell. also on the rifle is a replica eotech sight an acetech tracer unit and a peq box. it will also come with a hard case. I am open to offers on price.
