Automag J&J tarnished brass barrel straight rifled, 12 inch, used shape, no detent or orings Twistlock barrels require a wire or a plastic detent. Please see photos to see them. Some barrels have them included and some do not. Most included orings will need to be replace. If a wire / plastic twistlock detent is included it's likely okay but may need to be replaced at some point in the future. Straight rifled bore looks good.
