Trying to find out who makes the piston setup Ruger is useing on the rifle. I want to change the 16 inch to a 18 inch. My 6.8 has a Spc chamber I want to change to a SpecII. Does anyone have this info.

Rugers system is proprietary, I'm fairly sure Ruger is making the piston system and barrels in house.

Finally got to talk to Ruger. Yes they make their own parts
