I have the blued, standard version (not vented, not heavy lug) of the venerable 15-2 model (with adjustable sights). I have the 2.5" barrel, which is perfect for carry. I would like to find the 4" or 6" barrel & shroud. I am willing to sell the 2.5" barrel/shroud combination (a straight sale would be for $150, FTF Wash, or FFL otherwise). I would rather trade for the 4" or 6" barrel/shroud--and I am willing to add cash to make the deal work for you. Does anybody have an extra 4" or 6" barrel?
