Ruger Mark IV Target 22 LR 5.5 in Threaded Bull 10-Rd
About this product
The Ruger Mark IV Target 22 LR 5.5 in Threaded Bull 10-Rd is a precision .22 Long Rifle semi-automatic pistol engineered exclusively for range and competition use. This platform is a direct evolution of Ruger's legacy rimfire pistol design, refined to modern standards for reliability and ease of maintenance. It specifically addresses the target shooter who values repeatable mechanical accuracy and straightforward operation above all other considerations.
What is the Ruger Mark IV Target used for?
This pistol is designed for deliberate, stationary target shooting at the range. Its primary application is punching small groups on paper from a rested position, or competing in non-timed precision rimfire events. The heavy 5.5-inch bull barrel stabilizes the .22 LR round for minimal deflection, while the full adjustability of the rear sight allows you to chase a true mechanical zero over distances from 15 to 50 yards, which is where most formal target disciplines operate.
How does the Ruger Mark IV Target compare to a Browning Buck Mark?
The Mark IV Target offers a more modular and user-serviceable design than the Browning Buck Mark. Where the Browning uses a pivoting barrel retention system that can complicate disassembly, the Mark IV's one-button takedown allows you to field strip the pistol in under 10 seconds without tools—a decisive advantage for consistent, thorough cleaning. However, the Browning Buck Mark's adjustable trigger system is superior for fine-tuning the break and pull weight, making it the better choice for a shooter who prioritizes trigger feel above logistical simplicity.
What does it weigh and what are the dimensions?
This is a heavy, stable pistol meant for shooting from a rest, with an unloaded mass of 42.8 ounces (just over 2.6 pounds) and an overall length of 9.75 inches. The 5.50-inch bull barrel contributes a significant forward bias, lowering the pistol's center of gravity and reducing muzzle flip while adding nearly 14 ounces of stabilizing steel directly behind the suppressor threads. For scale, that's 9.3 ounces heavier than the barrel on the Stevens 334 .243 Win rifle, which speaks to the mass dedicated solely to rigidity.
Who is this NOT for?
Do not buy this if you need a plinker, a trail gun, or a suppressor host for dynamic use. The 42.8-ounce mass and precision-oriented sight geometry are liabilities in any scenario requiring quick presentation or handling. The satin stainless finish, while corrosion-resistant, will reflect light conspicuously in field conditions. For a .22 pistol meant for suppressed, off-hand fun, a lighter, compact-barreled model is a far better fit than this dedicated target tool.
What's in the box?
You receive the complete pistol, two factory 10-round magazines, a standard plastic case, an owner's manual, and a Ruger safety lock. Some distributors include a thread protector, but you must verify this on the order page, as suppressor-ready models often ship with the threads exposed. The two included magazines are critical, as they allow for structured range sessions with pre-loaded strings and mandated cool-down periods between targets, which is standard practice in the discipline this pistol is built for.
Is the Ruger Mark IV Target worth it at $695.99?
Yes, at this price point, it represents a competent entry into precision rimfire pistol shooting without the cost of full custom gunsmithing. You are paying for a purpose-built chassis—the heavy barrel, the stable steel frame, and the simple takedown system—that delivers consistent, cleanable mechanical performance. If your goal is to build fundamental marksmanship skills on a reliable platform before moving to centerfire competition pistols, this $695.99 investment grants access to that training track. For the hunter needing a more versatile field gun, the investment is better directed toward a rifle like the Stevens 334 in .308 Win.

Pros & cons
What works
- One-button takedown mechanism enables a complete field strip in under 60 seconds—no tools required.
- 5.5-inch bull barrel weighs 14 ounces, providing exceptional rigidity that minimizes harmonic vibration for consistent shot placement.
- Satin stainless steel finish resists corrosion from powder fouling and cleaning solvents, requiring less protective upkeep than blued steel.
Trade-offs
- Heavy 42.8-ounce mass makes it impractical for off-hand plinking or dynamic shooting drills.
- Checkered synthetic grips offer minimal texture compared to stippled or rubberized aftermarket options, reducing positive purchase.
- Fixed front sight is non-interchangeable without gunsmithing, limiting customization compared to pistols with dovetail mounts.

Frequently asked questions
- Is the barrel compatible with standard .22 LR suppressors?
- Yes, the 1/2"x28 threaded muzzle is the direct industry standard for .22 LR suppressors from SilencerCo, Dead Air, and Rugged. No thread adapter is required. Ensure your chosen suppressor is rated for the 5.5-inch barrel length, which all reputable .22 cans are.
- Does this pistol fit in a standard-sized pistol case?
- No, its 9.75-inch overall length typically exceeds the dimensions of a compact pistol case. You will need a full-sized pistol case or a dedicated rifle case compartment. Measure the internal dimensions of your case against the pistol's length before assuming it will fit.
- Can I use high-velocity .22 LR ammunition?
- Yes, the Mark IV action is designed to cycle reliably with standard and high-velocity .22 LR rounds up to approximately 1,600 feet per second. For optimal accuracy and reduced fouling, we recommend using match-grade standard velocity ammunition, which typically clocks around 1,080 fps.
- How long does the takedown and reassembly process take?
- A complete field strip, including bolt removal and cleaning, can be performed in under 60 seconds by a practiced user. The one-button mechanism reduces the process to pushing the takedown latch, separating the upper receiver from the grip frame, and pulling out the bolt assembly—all without tools.
