98c pump

I recently came across a 98c and I was wondering if it was possible to rig it into a pump. I don't really know how you would rig an in-line poppet to work as a pump.
Any help would be awesome or if there are other threads on this that I missed.
Also the tippmann has a pneumatic hose on the right side when looking down on the marker. My old 98c didn't have that, what is it?
Thanks

The hose is probably used for a Cyclone feed.
I could be wrong.

Can't help you with turning into a pump though, sorry.

inline poppets have been made as pumps for years, the first pump gun was an inline poppet,

the first paintball gun was an inline poppet, and a pump

Firstly you need to prevent the air from recocking the hammer. Now I believe this can be done by modifying the valve stem. I havent looked at a 98 valve that closely to know exactly how to do it but you need to restrict the airflow back into the hammer. You can do that by either milling a new stem or by attaching a stopper (seal) of kind to prevent airflow. DONT BLOCK AIRFLOW FORWARD.

Once the air is stopped you now have an open bolt pump. Your pump handle is the cocking pin. Congrats

If you want a TRUE pump (a closed bolt) you need to disconnect the hammer and bolt. The linkage rod needs to remain there the only difference is that either the bolt or the hammer needs to be slotted so that the linkage rod is fixed to one but slides freely along the other. Fixing the rod to the bolt and slotting the hammer I think is the better way to go but slotting the bolt is probably much easier.

Now mill a slot in the side of marker and connect a pump arm to the bolt. Then slide a sleeve over the barrel and connect that to the pump arm. Done.

Here's what I did. Modified valve with a feed tube tight to the body. The feed tube still comes off at the neck and a hopper can still be placed on. The pump base is mounted to the back body so that the gun still comes apart easy. Air is alot better with no blow back anymore.

Most of the time is in the pump handle and push rod. Stopping the blow back takes about 5 mins to do and can be switch back to semi in about 5 mins. I mostly use it as a pump, but have switched it back to semi to use like a pistol, just by removing the push rod and putting blow back on.

Couldn't you just remove the O-ring from the bolt

Yes you can just remove the ring but there will still be blow back causing the bolt to bounce and the marker will not be getting good air efficiency without a closed bolt. If you tried to run a 98 on 12g with the marker still blowing back, then you will get about 3-4 shots before losing distance. With a closed bolt your air efficiency is much better giving you more shots. Not making the marker the best in the world but better on air then a semi 98.

Removing the oring from the bolt will not stop the marker from recocking, it will only make it less efficient. The air that recocks the marker is from the valve.

I wish people would learn how their gun works before trying to troubleshoot a problem. On second thought, they should learn how it works before putting an air tank on it.
