Ruger Mark IV

.22 LR Pistol with Threaded Barrel, Optics Compatibility, and Rail System

The Ruger Mark IV combines .22 LR precision with practical features for accessory integration. Its cold hammer-forged barrel ensures superior rifling accuracy and durability. The threaded muzzle with 1/2-28 thread pitch supports popular muzzle devices, while integrated top and bottom Picatinny rails offer mounting flexibility. The aluminum grip frame is CNC-machined as a one-piece construction, paired with checkered synthetic grips for reliable control.

A simple one-button takedown system enables quick disassembly and chamber-to-muzzle cleaning without tools. Internal cylindrical bolt design delivers consistent sight-to-barrel alignment. Fixed front and adjustable rear sights are paired with a drilled and tapped receiver for Weaver- or Picatinny-style optics.

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