Unequaled quality, meticulous engineering and impeccable design are just a few of the reasons why Proto is the first name in paintball. We have advanced the new Proto Rail to the next level. It now includes our proven ergonomically designed Ultralite frame. The hourglass shape allows maximum control and comfort. The integrated heads-up display alerts you to the status of your marker. The new smaller, lighter Hyper3 In-Line Air Regulator comes standard. This new regulator provides higher flow, more consistency, better ergonomic grip and smoother velocity adjustment. The LPR has been reduced in size and is now vertically adjustable. The bolt kit operating pressure has been lowered by more than 10%, increasing the number of shots you get per tank. Take your game to the next level with the Proto Rail.
