I didn't, I bought it that way for peanuts!!, The lad had dropped it, The step down in the bull barrel to the reduced diameter isn't radiussed so snapping them is easier than most, Also, It's not high quality steel i'm afraid
The action that I took the Tracker barrel from was a fiver (Just barrel and cylinder), The broken Osprey was £30 so I can't complain for £35 and half an hour of my time when I was bored!
