This is a replacement 30 inch threaded magazine tube Winchester 1886 Rifle. This is the type 2 magazine tube that was seen on the 86's starting at serial number 110,000. The threads on the end of the mag tube screw into the receiver, cut 40 to the inch and shallow which subsequently lead to many tubes rusted into receivers. Tubes are blued and ready to go. Use magazine spring ms86. If you need tube length cut, please let me know.
