Superlative Arms Adjustable Gas Piston System, .750 Clamp-On Gas Block, Pistol-Length

The Superlative Arms Adjustable Piston System (Superlative Arms part no. SABO-PS-RFD-P750CM) converts a pistol-length AR-15 from direct impingement to a gas piston operating system, using a .750-inch clamp-on gas block that requires no gunsmithing or barrel modification. Pistol-length gas systems run under high pressure and heavy fouling, and piston operation keeps that fouling and heat out of the receiver, which matters even more on a short-barreled build. Superlative Arms built the system with an adjustable regulator, so shooters can dial gas flow down for use with a suppressor or up for reliable cycling with a wider range of ammunition. It is a genuine operating-system upgrade for pistol-length AR-15 owners who want cleaner, more tunable piston reliability.
