I have the above item that also has the carbon fiber sleeve installed. This is in 22 cal. Not glued in. The liner has been polished with JB borebright. I used it for about 70 shots on my Leshiy2. Probe and shroud are untouched. This is the newer dual port slug/pellet ports. Will sell for $300 shipped to lower 48. PP FF or Zelle.
