This Romerwerk .22LR is a bolt-action rifle with a .22 semi-automatic pistol built into the action, so it converts between the two forms. The rifle measures about 43.5 inches overall with a 26-inch barrel that has an excellent bore. The supplier notes about 95 percent blue remaining, a schnabel tip stock in excellent condition and a checkered hard rubber buttplate. Sights are a ramped blade front and a two-leaf rear. The listing marks it as used.

Collectors of unusual rimfire designs will focus on the combined rifle and pistol configuration and on the maker's markings. The takedown and conversion steps described by the supplier make the gun a study in mechanism as well as a shooter. Its .22 rimfire chambering suits range work, and the strong blue and intact stock make it a display candidate for a study collection.
