The ultimate in .22 target pistols. Volquartsen has a well deserved reputation for highly accurate, and dependable rimfire firearms. The Black Mamba continues that tradition with the use of Ruger's MKIV 22/45 lower with Volquartsen internals, topped off with the Volquartsen upper that features 4.5" threaded barrel with single hole compensator, competition bolt, fiber optic front sight, adjustable competition rear sight, and integral bottom rail. Comes in Volquartsen's hard case with two mags, and papers.
