I'm looking to pump my 99 STO, and I've already learned that I'm looking for a pre-99 kit.
Upon searching google, I've found two kits that will work. Both use similar components and material, yet the CCM branded one is $20 more. Is it worth the extra $20? CCM Light Weight Pump Kit for Pre 99/2k+ - e-Paintball Autococker Pump Kit - Pre 2k
There's also one that costs $77, but I suspect that is because the pump handle is made from aluminium instead of delrin. CCM Autococker 99 Pump Kit - e-Paintball
