This multi-position collapsible stock for the Tippmann X7 Phenom contains a hidden CO2 bottle threaded into a custom RAP4 Flexi-Air rear body plug—the only power source your marker needs! That means you won’t have to hang an unsightly CO2 tank from your ASA...and you won’t need to bother with a remote line, heavy pack, etc. The Buttstock Kit includes the 5oz CO2 bottle, which will provide you enough gas to get through several open play games or skirmishes during a hyper-realistic scenario.

Plus, the multi-position stock collapses and extends to give you a custom fit no matter your build or what tactical clothing you’re wearing! You’ll also notice how your marker balances much better with the diminutive bottle installed so discreetly inside of the stock.

You can remove the stock and swap the tank out with a backup 5oz tank in seconds...giving you the advantages of a concealed, onboard gas source without sacrificing time on the field!

This Buttstock Kit includes a RAP4 Flexi Air Kit rear body plug designed for your Tippmann X7 Phenom. This kit connects an internal air line to a standard ASA port in the rear, allowing you to thread the 5oz CO2 tank directly onto the rear of your X7 Phenom...and should you need an all-day-long air supply, you can remove the stock in seconds and replace that tank with the full size CO2 or HPA bottle of your choice! The (included) RAP4 Flexi Air Kit makes that happen!
