Dye Proto Rail Paintball Gun Color Coded o-rings make it easy to quickly identify the correct replacement o-ring when performing maintenance of your marker. The Eye Pipe, patent pending, internal design houses multiple critical systems that ensure worry free performance. The polycarbonate pipe shields the self-cleaning anti-chop eye system from dirt and broken paint ensuring the eyes are always monitoring the breech and ball drop. The seamless pipe is wiped clean by the bolt tip o-ring on every cycle. The Eye Pipe system eliminates miss feeds, and double feeding. In addition it eliminates external eye plates and the potential of striped or corroded plate mounting screws. The proven Hyper regulator design has been greatly improved. Now introducing the Hyper3 in-line regulator. This new design is sleeker, smaller, consistent and offers precise increments of air pressure adjustment. Our new shim stack is more responsive and reacts quicker to pressure changes allowing better flow and a faster response. The size has been dramatically reduced allowing us to incorporate the soft rubber our proven Sticky Grips. In addition, the Hyper3 air input swivel ring allows it to work with all bottom line configurations.
