CA G36c. Mostly everything gearbox related is aftermarket, save for gears and motor. Stock bucking, madbull python barrel, basic gate mosfet. Aoe and shimming done. Note the the imgur album for issues. One rear sight square has a tab broken, a body pin has the threads removed (still holds fine), and the handguard retainer is 3d printed. Comes with 2 old hi caps, for an extra $10 you can have 4 midcaps too. 120 plus shipping. Just taking up space, buy this please. I can likely ship same/next day. http://imgur.com/a/wYZR4wg
