The patent-pending RAP4 Flexi-Air system for the Tippmann X7 Phenom adds a realistic look and feel to your marker by allowing you to get rid of the external air hoses, relocate your air source, and increase the marker’s performance as well


Hybrid Collapsible Stock


The Hybrid Collapsible Stock serves to break the barriers of traditional air through and air in stock systems by enabling a user to seamlessly switch between using a 13 cubic inch air cylinder or a remote line.

Adding to it unparalelled functionality, the HCS also offers all of the cosmetic and ergonomic benefits of some of the most popular firearm configurations for unbeatable compactness and close quarters performance.

With the included remote airline fitting, you will have the ability to swivel the fitting on the bottom of the stock much like our second generation CATS stock. This fitting will accept any 1/8″NPT air fitting.
