Key Features
- One-Button Takedown – Press a single button to pivot the barrel assembly forward for complete chamber-to-muzzle cleaning. This eliminates the need for tools or wrestling with stubborn parts, saving you time at the range or workbench.
- 6" Tapered Barrel with Fixed Sights – The longer sight radius and fixed sight setup give you a consistent, zero-maintenance sight picture. This matters for shooters who want repeatable accuracy without worrying about drifting adjustments.
- Synthetic Checkered Grip – The molded polymer grip provides a secure hold even with sweaty or gloved hands. It reduces fatigue during long sessions and keeps the pistol on target through rapid fire.
- Two 10-Round Magazines Included – Having a spare magazine means less downtime reloading. Per Ruger specs, both mags are steel with a polymer base pad for easy handling and reliable feeding.
- One-Piece Machined Grip Frame – The frame is machined from a single piece of aluminum, not cast or welded. This gives the Mark IV its signature balance and durability, making it a solid platform for thousands of rounds of .22 LR.
Who It's For
This pistol is built for shooters who want a reliable, easy-to-maintain rimfire handgun for high-volume target practice, training new shooters, or plinking. It suits anyone who prefers fixed sights over adjustable ones and values quick disassembly for cleaning. If you already own a Ruger Mark III or 22/45, the Mark IV’s one-button takedown is a clear upgrade.
Pros & Cons
- Pro: Takedown is genuinely one-button – no tools, no pin alignment, no frustration. You can field-strip it in under 10 seconds.
- Pro: The 6" barrel gives you a sight radius that helps tighten groups at 25 yards compared to shorter barrels.
- Pro: Aftermarket support is massive – grips, triggers, barrels, and optics mounts are widely available.
- Con: Fixed sights are not adjustable for windage or elevation. If you need to zero to a specific ammo or distance, you’ll need to file the front sight or swap to an aftermarket rear sight.

FAQ
Does the Ruger Mark IV Standard .22 LR 6" Blued Fixed-Sight come with a threaded barrel?
No, this model has a standard 6" tapered barrel without threads. If you need a suppressor-ready barrel, look at the Mark IV Target or 22/45 Tactical models.
Can I mount a red dot on this pistol?
Not directly – the fixed-sight version has no factory optics cut. You would need to purchase a separate mount that replaces the rear sight or install a Picatinny rail adapter, then use a red dot that attaches to that rail. The Mark IV Target model comes with a Weaver-style rail if that is a priority.
What kind of accuracy can I expect with the fixed sights?
With quality ammunition, the 6" barrel and fixed sights are capable of 1.5–2 inch groups at 25 yards from a rest. The sight radius helps, but the fixed sights limit windage adjustment – you may need to hold off for POA/POI shifts with different ammo.
Does this pistol work with both standard and high-velocity .22 LR ammo?
Yes, the Ruger Mark IV cycles reliably with standard velocity (around 1070 fps) and high-velocity (1200+ fps) .22 LR loads. Per Ruger specs, avoid subsonic ammo below 1000 fps if you want consistent slide cycling.
How many magazines come with the Ruger Mark IV Standard?
Two 10-round magazines are included in the box. They are Ruger factory mags with steel bodies and polymer base pads.
