Was supposed to be a CQB build for accuracy/trigger response. Done the build before, gives near instant response with the JG Blue/Red and a 7.4v lipo. This set has most of the pieces you need, but I'd recommend having your own set of stuff lying around. I found this while moving and will most likely only play casually and (hopefully) never tech again. Notable items: -Franketorque motor. Holds up bolt cutters, blows the puny hammer test right out of the water. -ball bearing spring guide SHS, purchased from Clandestine. -SHS 12:1 gears Great trigger response and torque -SHS air nozzle, JG/SHS cylinder head and SHS cylinder. Perfect air seal. -JG/SHS Whatever piston, 10 of the rear teeth are metal. Hefty boy. -Deans rig with mosfet. Also comes with a crummy 8.4v NiMh wired to deans. I think I broke the tappet putting it back together. Shim job is also pretty terrible. I haven't radiused the cylinder area either. comes with other VFC bits and pieces. $100 shipped. OBO Trades -A real military-issued current date assault pack -Also Volvo 240 Parts? -Gopro 3 or 4 (I can add cash) -Yamaha FZ6 stuff -I'll consider other non-airsoft trades as well.
