A popular upgrade available for Tippmann markers. Get to a higher rate of fire easier with air assistance. Every time the marker fires, a piston is used to assist the spring return on the trigger. Find the right amount of tension and you've maxed out the rate of fire for the marker. Completely adjustable to you!

Now includes a longer hose and instructions for installing in a Project Salvo.

This kit does NOT contain the pre-drilled power tube.  If you have an 98 Custom, pre 1022801 serial number, or Custom Pro, pre 0015601 serial number, with no TA05021 power tube plug, you will have to drill your power tube port, or order the pre-drilled version 98-21NR.  See related products.
