DescriptionThe new Proto SLG UL includes patented Spool Valve Technology, which allows the gun to operate more consistently at a lower operating pressure, giving you 1500 shots on a 68/4500-air tank. In addition, the new multifunction, self-lubricating Force Button allows clearing the bolt without tools, acts as a cocking mechanism, and prevents unsafe disassembly of the marker when gassed up. The SLG comes standard with the new Hyper3 In-Line Air Regulator featuring higher flow, more consistency, and smoother velocity adjustment. Regular maintenance and cleaning are easy with one-tool-one-screw bolt breakdown. The Proto SLG consists of solid construction using a hardened steel sear, aluminum body and bolt, and a reinforced polymer frame and trigger. All this adds up to a tournament grade package you can afford.Features: - No-Rise Pressure Feed-Neck- Single Piece Proto Barrel- Anti-chop Break Beam Eye System- Orbital Rotating Sear Reduces Wear- Compact Lightweight Body Weighing only 2lbs 2oz!- STAMPED METAL INSERT LOGO- New Self-Closing Valve(SCV) 2-Piece Bolt- Multifunction Self-Lubricating Force Button- Super Low 145psi Operating Pressure- Adjustable Reinforced Polymer Trigger- Ergonomic 45-Grip Frame- New Hyper3 In-line Air Regulator- Proto Dual-Durometer Injection Sticky Grip- Program with Four Tournament Modes- Proto Bottom-Line with DovetailThe new Proto Matrix SLG destroys everything you thought about entry-level markers.
