Ruger Mark IV

.22 LR Pistol with Extended 254mm Bull Barrel and Adjustable Rear Sight

The Ruger Mark IV with its extended 254mm bull barrel offers increased sight radius and superior accuracy for target shooting. Built with an alloy steel receiver and a CNC-machined aluminum grip frame, it combines solid performance with refined handling. The cold hammer-forged barrel ensures long-lasting rifling precision, while the internal cylindrical bolt construction delivers permanent sight-to-barrel alignment.

The synthetic grip panels are checkered and ergonomically shaped for confident handling. A tool-free one-button takedown enables easy disassembly and cleaning from chamber to muzzle. Fixed front and adjustable rear sights are complemented by a drilled and tapped receiver for Weaver- or Picatinny-style rail mounting.

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