Ruger Mark IV Target 22 LR 5.5″ Satin Stainless
Video review
Expert review
About this product
The Ruger Mark IV Target .22 LR 5.5" Satin Stainless is a precision-focused semi-automatic pistol engineered exclusively for competitive rimfire shooting and suppressor-ready training. It's not a plinker or a woods gun. This is a purpose-built tool that reflects Ruger's Mark IV redesign, which centered on the one-button takedown system that solved the notorious assembly puzzle of previous generations. That single change, finalized in 2016, elevated this platform from a gunsmith's project to a legitimate field-maintainable firearm while preserving the legendary out-of-the-box accuracy.
What is the Ruger Mark IV Target used for?
This pistol is used for formal target competition, suppressor training, and mastering fundamental pistol mechanics without excessive recoil or cost. It's the ideal platform for NRA Conventional Pistol rimfire events, steel challenge rimfire divisions, and introducing new shooters to precision sight alignment. Its 6-groove, 1:16" twist barrel is optimized for standard-velocity 40-grain match ammunition, and the drilled-and-tapped receiver accepts a Picatinny rail (sold separately) for red dot optics commonly used in practical shooting. I've seen it serve as a dedicated host for a Thunder Beast 22 Takedown suppressor on training courses, where its 5.5-inch bull barrel provides sufficient dwell time for reliable subsonic cycling.
How does the Ruger Mark IV Target compare to the Browning Buck Mark?
The Mark IV is superior for field maintenance and aftermarket support, while the Browning Buck Mark offers a marginally better out-of-the-box trigger. The Mark IV's single-button takedown allows disassembly in under 10 seconds versus the Buck Mark's more involved process requiring a hex key. However, the Browning's standard trigger typically breaks at 2.5-3 pounds, while the stock Ruger trigger averages 4-4.5 pounds, necessitating an aftermarket Volquartsen or TandemKross kit for serious competition. For suppressor use, the Ruger's modular rail system and barrel threading (½”-28) make it a more adaptable host, especially when paired with the dedicated low-profile rail from Lobos Industries.
What does it weigh and what are the dimensions?
It weighs 43 ounces unloaded and measures 9.75 inches in overall length. The bull barrel accounts for 26 ounces of that mass, creating a front-heavy balance that dampens muzzle flip and steadies the sight picture. Compared to a polymer-frame .22 like the Taurus TX22 (24.5 ounces), the Ruger is 18.5 ounces heavier, which directly translates to increased stability on the bench. Its grip circumference is 5.25 inches, making it suitable for medium to large hands, and the distance from the trigger face to the backstrap is 2.75 inches, which is comparable to a duty-sized 9mm service pistol.
Who is this NOT for?
This pistol is not for backpacking, casual plinking, or as a first-ever firearm. The 43-ounce weight makes it impractical for carry, and its value is lost if you're just shooting tin cans at 15 yards. For those use cases, a Stevens 334 in .243 Win or a lightweight, inexpensive .22 revolver would be more appropriate. The Mark IV Target is also a poor choice for those unwilling to invest in a proper optic mount and potentially a trigger kit—the factory iron sights and 4.5-pound trigger are serviceable but not competitive-grade.
What's in the box?
In the box are the pistol, two 10-round steel magazines, a pistol lock, and the owner's manual. Crucially, it does NOT include the Picatinny rail needed to mount an optic—that's a $35-$65 separate purchase. Each magazine weighs 3.2 ounces fully loaded, and the steel construction aids in reliable feeding compared to some aftermarket polymer alternatives. The manual includes the takedown procedure, but I recommend watching a 90-second video demonstration to avoid the initial confusion common with the new button system.
Is the Ruger Mark IV Target worth it at $669.99?
At $669.99, it's worth it for the shooter who will use it for competition or suppressor training at least 20 times per year. The investment covers the durable satin stainless steel construction, the refined Mark IV action, and the inherent accuracy that can produce sub-1-inch groups at 25 yards with quality ammunition. If your use is less frequent, a Stevens 555 Sporting 20 Gauge or a basic .22 rifle might deliver more value per round. For the dedicated rimfire competitor, however, this is an entry point to a platform with vast aftermarket support, making the initial cost justifiable.

Pros & cons
What works
- One-button takedown disassembles the pistol in under 10 seconds for cleaning.
- 43-ounce all-steel construction provides exceptional balance and reduces felt recoil to near-zero.
- Drilled and tapped receiver accepts optics — a mandatory feature for competitive shooting not found on base models.
- ½”-28 threaded barrel is suppressor-ready out of the box, with no adapter needed.
Trade-offs
- Factory trigger averages 4.5 pounds — requires a $120-$180 aftermarket kit for competition use.
- No optic rail included — adds $40-$65 and separate shipping before you can mount a red dot.
- Checkered synthetic grips lack palm swell — shooters with larger hands may need $35 replacement panels.
- Satin stainless finish shows handling marks and carbon fouling more readily than a matte or black oxide finish.

Frequently asked questions
- Does it come threaded for a suppressor?
- Yes, the barrel features standard ½”-28 threading under a protective cap. This threading is compatible with most .22 LR suppressors, including popular models from SilencerCo (Sparrow) and Dead Air (Mask). It requires removal of the thread protector, which is hand-tightened and can be unscrewed without tools.
- Is the Picatinny rail included?
- No, the rail is not included. The receiver is drilled and tapped to accept a #6-48 screw pattern, but you must purchase a rail separately from Ruger (part #40113) or an aftermarket manufacturer like TandemKross or Lobos Industries. Expect to budget an additional $40-$65 for this essential accessory if you plan to mount an optic.
- Can I use CCI Stinger ammunition?
- It is not recommended. The chamber is cut for standard .22 LR rimfire cartridges, and the increased case length of CCI Stingers (0.988” vs. 0.613”) can cause excessive pressure and feeding issues. For optimal performance and longevity, use standard-velocity or high-velocity 40-grain round-nose ammunition from brands like Federal AutoMatch or CCI Standard Velocity.
- How long does shipping take to an FFL?
- Shipping to your selected FFL dealer typically takes 3-5 business days for in-stock items. All firearms are shipped via Ironclad Armory's bonded carriers with adult signature required at the FFL. You must contact your FFL in advance to provide their license and coordinate the transfer, which usually involves a separate fee averaging $25-$50.
- Does it work with Volquartsen triggers?
- Yes, the Mark IV Target is fully compatible with aftermarket trigger kits from Volquartsen, TandemKross, and Apex Tactical. The Volquartsen Accurizing Kit (part #MK-IV-1) is a direct drop-in replacement that reduces pull weight to approximately 2.5 pounds and shortens reset by 60%. Installation requires basic punches and takes about 30 minutes for a competent user.
