R1 new gas piston assembly in R1 Rifle Posted September 4, 2020 I ordered a replacement cylinder plunger piston (because the build up was ugly) and the porting on the new cylinder was different than my R1 so I ordered a complete gas system kit and the piston ports on the cylinder in the kit was similar but the throat of the cylinder was different. I have a 30-06 caliber R1. Benelli, which cylinder pin is the most up to date and appropriate for my rifle? There is zero information on the web about this. A service advisory on this would be an excellent service for your loyal clients. I want to install a new pin. Which one do I install?????
