I acquired seven rifles that were in rather poor cosmetic condition. They were packed with grease and dirt and had the stocks spray-painted black. I decided to refinish them, but my references didn’t include an exploded view. Even Numrich Gun Parts Corp only showed major components. Hopefully these notes will assist anyone else doing a complete A&D for cleaning, repair or refinishing.
The gas system consists of the actuator (gas-capture cup), actuator lock nut, gas cylinder, driving spring, driving spring plunger, and connector. The system may be disassembled for cleaning, but may not be removed from the barrel without removing the front sight assembly.
