The barrel is my own custom made "suppressed" real carbon fiber barrel. The externals consist of a MadBull MUR Noveske receiver, stubby stock vinyl carbon wrapped, 7inch keymod, one of my real carbon barrels, 230mm Angel tightbore flat hopped, Maxx Hopup, Krytac defiance grip, retro arms selector, butterfly charging handle, speed trigger. The ultimate DSG gearbox: Retro Arms gearbox, Siegetek 14:2 gearset, Gate Titan Advanced, SPEED strigger, Kratos piston. RA tappet. Shoots 45 rps @ 350fps really reliably with 11.1v and m150 spring. Includes an almost new ASG Infinity 22,000 motor that I custom shimmed the magnets on and also put a Siegetek pinion on. Make offers, I have it priced at what I paid for all the parts alone, not to mention my time to work on it is not in that number. I spent more than a few hours. I wanna get $100 OBO but we can talk.
