Hello ladies and gents!
I just figured out how to make the cheapest pump kit for a 98 custom. I know your thinking why would you pump a custom? well....SOME OF US ARE PO' and we can't afford a trilogy $60+ pump kit $35 = 95 buckaroo's! I don't have that much and you don't need to spend it either!
The first thing you need to do is take apart your tippman and get to the bolt, then you need to take the oring off, and then your done.
Put it back together and take rod or some long thing, bolt it or duct tape it to the cocking pin the the make some sort of pump handle out of a soda bottle or buy one if your NOT PO'. then go have some fun with you new ghetto pump tippmann.
NOTES: This will give you the same shot count as before. All you are doing is letting the blowback gas escape out the bolt.
I will have hopefully a video and more pics up tomorrow. I have to go mill a pump handle.
