This Ruger Mark IV target upper receiver is a factory take-off removed from a brand new pistol right out of the box. It gives buyers a genuine Ruger upper for a replacement project, a second upper setup, or a custom build with factory components instead of aftermarket alternatives.

This target upper features a 5.5″ threaded bull barrel, factory sights, and a black finish, so it is a strong option for shooters who want a factory Ruger upper with threaded-barrel capability. In addition, it fits all Ruger MK IV and MK IV 22/45 models. It also comes from the Collector’s Series and carries special serial numbers in the RCS8-xxxxx range. As a result, buyers get a factory upper with both practical features and added Collector’s Series appeal. Free shipping adds even more value to the package.
