Ruger Mark IV

.22 LR Pistol with 140mm Bull Barrel and Target Laminate Grips

The Ruger Mark IV combines classic .22 LR performance with ergonomic refinement, featuring a cold hammer-forged 140mm bull barrel for precise rifling and extended barrel life. The CNC-machined one-piece aluminum grip frame and contoured laminate target grips with finger grooves offer excellent control for precision shooting.

A tool-free one-button takedown system allows for fast field-stripping and maintenance. The internal cylindrical bolt system ensures permanent sight-to-barrel alignment, enabling superior accuracy over traditional designs. The pistol includes a fixed front sight, adjustable rear sight, and a drilled and tapped receiver compatible with Weaver- or Picatinny-style rails.

Additional features include ambidextrous manual safety (convertible), left-side magazine release, magazine disconnect, and two 10-round magazines.
