This gun is so old and been a part of my life it’s like a child and weighs more than one too. This chungus is held together by the sheer will to shoot bbs down range. Ran this thing all weekend at Fulda Gap 2012 on Tan side back at ducket. Handguard: is a&k rail that is rigged up and not gonna move. Wired on deans. Pressure switch ghetto wired up to the box mag but works ( i was young my finesse with solder hadn’t developed yet. I swear it doesnt happen any more! Also i only had a buds dremmel and cut wheel o make a hole in the back for the wire!) the button on the bottom still works! Standard barrel and classic army hop up . Have a spare echo1 hop up that will come with. Ps. thing this is heavy and most satisfying laying down cover fire for your squads. Shipping is expensive pls keep that in mind when making offers if i get asking price i will half the ship the cost.
