NO TRADES. price is firm but I cover PayPal fees and shipping for free. Gearbox was only fielded 3 times and motor is brand new. The gearbox is at worth $150 new and comes with $60 krytac motor and $30 krytac grip Selling no returns simply because installing the gearbox requires basic teching skills so that’s on you to know how to do, but I will provide shooting videos if needed and have a lot of vouchers to back my product quality.
