The Parts You Need To Rebuild An Old Tube
For most of the older .22’s that no longer have a factory replacement magazine tube, this kit provides the parts needed to custom-make a magazine to fit. All tube blanks have a rolled crimp on one end only. Kit No. 2: .350" O.D. tube, 22-3⁄8" (56.8cm) long. 32" (81.2cm) spring with follower, plug and cross pin. For some Marlins, Remingtons, Stevens and others. Will not fit tubular magazines with a plastic follower such as the Marlin model 60 or derivatives of it.
