Ruger Mark IV
.22 LR Stainless Steel Pistol with 254mm Bull Barrel and Adjustable Rear Sight
The Ruger Mark IV is a robust, precision-built .22 LR pistol designed for extended accuracy. Its 254mm cold hammer-forged bull barrel delivers superior rifling and long-term performance, while the full stainless steel grip frame and receiver provide durability and balance. The internal cylindrical bolt ensures permanent sight-to-barrel alignment for enhanced target precision.
The grip is contoured with a natural pointing angle and checkered synthetic panels for non-slip control. The simple one-button takedown system allows tool-free disassembly and cleaning from chamber to muzzle. The pistol includes a fixed front sight, adjustable rear sight, and a drilled and tapped receiver for Weaver- or Picatinny-style rail mounting.
Features include a left-side magazine release, ambidextrous manual safety (convertible), magazine disconnect, and two 10-round magazines.
