Ace Barrels blank that I purchased for a project that is now on hold for a while. Stainless steel, #3 contour (similar to Bartlein 3b or Brux #5), 26" max finish length, 1:9 twist cut rifling. These are great barrels that shoot very well. $325 shipped. Please PM with questions. No trades. Thanks! Barrel is in original box, so I do not have pictures at this time. Will unpackage if needed.
