I will give you a Odyseey million dollar sprocket (Black), a Bulldog Crank set (Chrome) and a Red Halflink chain and a BT-4 Ironhorse paintball gun, with an adjustable sight and Grip, When I bought that gun it was about 600$ firm and the parts were 300$ firm. So, get back to me. I can't include a barrel or a hopper, Unless you really want a hopper with a chipped jar, the gun is in almsot perfect shape and so are the sight and grip. Please get back to me, thanks.
