Check the listing for details. Matrix Precision - Ruger MK 1, 2, 3, 4 IV Competition Bolt - Gold. Color: Gold, Condition: New, Made in United States. Listed at 149.00 USD. Hi Matrix, I know a lot of people have been reporting great success on Reddit, and I love that you are replying on the Ruger forums. I never touched the other springs! Before swapping to a Volquarten recoil spring, I was getting 5-7 failure to cycle/failure to eject per hundred rounds.
