Ruger Mark IV Competition .22 LR 6.88" Slab-Sided

Ruger Mark IV Competition: Purpose-Built for the Target Range

The Mark IV Competition represents Ruger's commitment to delivering a serious .22 LR pistol for competitive shooters and precision enthusiasts. This is a firearm engineered with one clear objective: accuracy and reliability.

Design and Ergonomics

The Mark IV features a distinctive slab-sided bull barrel measuring 6.88 inches—a length that provides excellent sight radius and velocity for .22 LR ammunition. The lightweight aerospace-grade aluminum receiver keeps overall weight manageable at 45.8 ounces, while the satin stainless steel finish resists corrosion and presents a professional appearance.

The checkered laminate grips with thumbrest are designed for control and comfort during extended shooting sessions. An ambidextrous manual safety can be converted to left-side only using the included washer, accommodating shooters of all preferences.

Accuracy and Sighting

Accuracy is paramount in competition, and Ruger addressed this with:

• Fixed front sight paired with an adjustable rear sight for precise zeroing
• Drilled and tapped receiver compatible with Weaver and Picatinny rails for mounting optics
• Internal cylindrical bolt construction that maintains permanent sight-to-barrel alignment—a significant advantage over conventional moving-slide designs
• 1:16 right-hand twist optimized for .22 LR ballistics

Reliability and Maintenance

The Mark IV's one-button takedown system allows field-stripping without tools. A recessed button in the frame's rear lets the upper receiver tilt up and away from the grip frame, providing complete access to the barrel and chamber for thorough cleaning—essential for .22 LR shooters who understand fouling management.

The ergonomic bolt stop and easy-to-grasp bolt ears ensure reliable operation round after round. A contoured ejection port accommodates smooth case ejection.

Magazine and Controls

Two 10-round magazines ship with the pistol. The push-button magazine release is conveniently located on the left side of the frame, and magazines drop free upon release for faster reloading. A magazine disconnect prevents discharge when the magazine is removed—a safety feature that matters.
