Selling an LCT AK with upgraded gearbox and madbull barrel. Gearbox has a high speed motor, upgraded nozzle, piston, makes perfect airseal Full metal picitinny front rail system. Will include leo style stock not the krytac stock. M90 spring for cqb (330-350fps). Gearbox occasionally gets stuck on semi auto, just need to reset selector switch and it can go full auto. I estimate 20-25 rps, will send test fire video if interested. PayPal only buyer pays shipping, will have to partially disassemble to ship! NO TRADES thanks
