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

The Superlative Arms Adjustable Piston System (Superlative Arms part no. SABO-PS-RFD-C750CM) converts a carbine-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. Superlative Arms built the system with an adjustable regulator, letting shooters fine-tune gas flow to run suppressed, with a wide range of ammunition, or in adverse conditions without over-gassing the rifle. Piston operation keeps combustion byproducts out of the receiver, so the action stays cleaner and drier than a direct-impingement gun over a long shooting session. It is a genuine operating-system upgrade for carbine-length AR-15 owners who want piston reliability without a full upper rebuild.
