Bob Long 4-Stage Co2 Expansion Chamber
The Bob Long 4-Stage Expansion Chamber effectively converts liquid CO2 into gas. Liquid CO2 is drawn thru the bottom chamber and travels through a series of chambers where the liquid and air are mixed evenly; giving a more consistent flow of pressure to the valving of the marker. This is one of the largest increases in performance co2 guns can have. Works with Autocockers, Automag, Spyders, tippmanns and many more. Works in any position. Screws into any vertical ASA and attaches to standard 1/8" NPT hose.
