I have to say, after a couple hundred rounds down the pipe, the CST action runs, loads, feels, and even sounds like a heavy centerfire rifle action — not unlike a Browning BAR. What really impressed me is that this action will reliably cycle any ammo I load, including some of the Aguila bulk ammo from Mexico. That stuff will not run in any other 10/22 builds I’ve made.
I fully intend to use your actions in any future higher-end 10/22 builds.
