Used, non rotating 90 degree macroline fitting, not standard style. Plated brass, oring will be replaced. One included. Multiples available so condition will differ slightly. I will replace the oring in these macroline fittings before they ship.These DO NOT rotate. You screw them in to the position in your regulator or marker that you want and they hold that position. Most people prefer the rotating macro line fittings. These DO NOT rotate and they are not the standard style found on most paintball markers.
