      I got a black one I picked up here cheap its got a J&J barrel and believe an upgraded valve. Haven’t put air to it in a while but I can check it out tomorrow if you are interested. I picked it up for our blowback throw back game. But I have plenty of blow backs.

                    These are very early. If you buy one, might be useful to shorten the valve pin slightly to reduce blowback up the feedneck.
