Original, 150+ year old inner magazine tube for 1860 Spencer rifle and carbine. This tube screws into the receiver and is in perfect usable condition. These brass tubes were only used on the very first Spencers as they were soon replaced with more robust steel tubes. This brass tube is a must for an early serial numbered gun. These extremely hard to find tubes are very hard to find, so don't wait. Increase your guns value with original parts!
