Gemtech 8889326 Threaded Rear Mount Adapter For Fixed Barrels 1/2-36 TPI

It’s the classic American long gun, a tool of history and just as much a symbol of the Old West as the six-shooter. The Marlin® brand is synonymous with lever-action repeaters. It’s a rich tradition, with a heritage stretching back to the Model 1881, Marlin’s first centerfire, and the Model 1891, their first rimfire. In fact, Annie Oakley trusted the Model 1891 above all others to demonstrate her legendary marksmanship.
