I have a 10/22 takedown but it's not stainless. It does have a threaded barrel. My plan is to upgrade the barrel to a TacSol SB-X Takedown and sell the original barrel. I could always reverse the order, selling the original and then getting the TacSol. If you're interested, Sainte70, send me a PM and we can discuss it. flamatrix99, this is Sainte70's thread so it's only fair I give him first right of refusal. I'll have to look at the TacSol website again. I know they used to use some of the original Ruger parts for the Ruger barrel but TacSol may be including them now. If they are not, I would have to keep some of the parts and you would have to move some of your parts from your existing barrel.
