Ruger Mark IV

.22 LR Stainless Steel Pistol with 140mm Bull Barrel and Adjustable Rear Sight

The Ruger Mark IV in stainless steel delivers precision and durability with a 140mm cold hammer-forged bull barrel that provides exceptional rifling accuracy and longevity. The solid stainless steel grip frame is CNC-machined in one piece for added strength, and the checkered synthetic grip panels offer a secure, non-slip hold.

The internal cylindrical bolt ensures permanent sight-to-barrel alignment, offering greater potential accuracy than conventional systems. Maintenance is simplified with a tool-free one-button takedown, enabling quick chamber-to-muzzle cleaning. The adjustable rear sight and drilled and tapped receiver support Weaver- or Picatinny-style optic mounting.

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