Barrel for a .22 slug project I never got around to. Never used or mounted. The barrel is stainless steel and the internal diameter is smaller than OEM to more snuggly fit the .22 liners for added rigidity (no need for carbon sleeves). Also including an Ernest Rowe dual transfer port in .22 (no low power side). Asking for $135, negotiable. Paypal F&F preferred (or buyer covers fees). I'll cover shipping. US only.
