The rifle’s design prioritizes function. The black synthetic stock is durable and weather-resistant, while the semi-automatic action is built to handle the higher pressure of the .22 WMR round reliably. At a weight of around 5.5 pounds, it’s a rifle you can shoulder for hours without fatigue. The action is typically compatible with common aftermarket triggers and accessories designed for the platform, much like those for a Ruger 10/22, allowing for customization. The real advantage here is the cartridge—when it comes to dispatching raccoons in the henhouse or groundhogs at 100 yards, the .22 WMR hits with authority that standard .22 LR can’t match.
Who This Rifle Is For
This is the tool for the Missouri landowner or hunter who needs a step up from a .22 LR. It’s for the shooter managing coyote populations, protecting property from destructive pests, or simply wanting a flat-shooting, low-cost practice rifle with more reach. It’s also an excellent choice for a newer shooter looking to graduate to a more capable rimfire, thanks to its manageable recoil and straightforward operation. With a price of $751.06, it sits as a serious rimfire option for serious field work.
Pros & Cons
Pros: The .22 WMR cartridge offers excellent terminal performance on varmints up to coyote size. The 18-inch barrel squeezes out all available velocity. The integrated rail means your optic mounts solidly right out of the box. Recoil is minimal, making it pleasant for extended shooting sessions. Magazine capacity is generous for the caliber.
Cons: Ammunition cost is higher than .22 LR. The report is louder, so hearing protection is non-negotiable. Some may prefer a traditional rifle stock over the synthetic design. Being optics-ready, it requires an additional purchase to use iron sights.
Frequently Asked Questions
Q: What optics mount directly to the Weaver rail?
A: Any standard Weaver or Picatinny-style ring mounts will secure directly to the rail. This includes popular scope rings from brands like Leupold, Vortex, and Warne, as well as a vast array of red dot sights. It’s a universal interface.
Q: Is the .22 WMR suitable for self-defense?
A: While it possesses more power than .22 LR, the .22 WMR is generally not recommended for primary home defense. Its strengths lie in varmint hunting and pest control where its accuracy and energy are ideal. For two-legged threats, a centerfire rifle or shotgun is a more reliable choice.
Q: What’s the real-world effective range?
A: With its 18-inch barrel and the right ammunition, the MR-22 is capable of consistent, ethical hits on small game like prairie dogs and jackrabbits out to 125 yards. For larger varmints like coyotes, keeping shots inside 75 yards is advisable for a quick, humane takedown. That said, its flatter trajectory makes longer shots more predictable than with .22 LR.
