Winchester Wildcat SR .22 LR 10rd OD Green/FDE
About this product
What is the Winchester Wildcat SR .22 LR 10rd OD Green/FDE? It's a semi-automatic rimfire rifle optimized for lightweight training, small-game hunting, and suppressor-ready applications, built around a polymer receiver and featuring a two-tone OD Green/FDE finish. The design incorporates ambidextrous controls, a detachable 10-round rotary magazine compatible with Ruger 10/22 pattern magazines, and integrated Picatinny optics mounting. At 4 pounds unloaded, this platform balances maneuverability with the mechanical precision needed for consistent rimfire performance.
What is the Winchester Wildcat SR used for?
The Winchester Wildcat SR serves as a dedicated training rifle, suppressor host, and small-game harvesting tool where low noise and minimal recoil are priorities. I've found it particularly effective for introducing new shooters to semi-automatic platforms, thanks to its 10-round capacity and last-round bolt hold-open feature. The 1:16" twist rate stabilizes standard and high-velocity .22 LR ammunition reliably, making it suitable for targets up to 75 yards.
How does the Winchester Wildcat SR compare to the Stevens 334?
The Winchester Wildcat SR offers semi-automatic functionality at nearly half the weight of the bolt-action Stevens 334 in .308 Win, making it better for rapid follow-up shots and high-volume training. Where the Stevens platform delivers centerfire power for big game, the Wildcat focuses on rimfire economy—firing 500 rounds costs approximately $40 versus $350 for comparable .308 practice. The polymer construction and takedown design also simplify maintenance compared to traditional bolt-action rifles.
What does it weigh and what are the dimensions?
The rifle weighs 4 pounds (64 ounces) empty and measures 37.25 inches in overall length with a 18-inch barrel. The stock includes 1.5 inches of length-of-pull adjustment via spacers, accommodating shooters from 5'4" to over 6' tall. Barrel diameter tapers from 0.75 inches at the receiver to 0.56 inches at the muzzle, contributing to the lightweight handling characteristics.
Who is this NOT for?
This rifle is not suitable for hunters requiring terminal energy beyond 150 foot-pounds or engagement distances exceeding 100 yards. The .22 LR cartridge lacks the authority for ethical deer or hog harvesting, where a platform like the Stevens 334 in .243 Win would be appropriate. Competitive shooters needing sub-MOA accuracy will also find the 2-3 MOA mechanical limitations frustrating compared to dedicated target rifles.
What's in the box?
The package includes the complete rifle, one 10-round rotary magazine, and a basic owner's manual covering disassembly procedures. Unlike some competitors, no optic mounts or cleaning kits are included—expect to budget $25-50 for appropriate rings and a .22 caliber cleaning rod. The manual clearly outlines the 3-step takedown process for barrel and receiver separation.
Is the Winchester Wildcat SR worth it at $297.99?
At this price point, the Wildcat SR delivers exceptional value for trainers and recreational shooters prioritizing lightweight handling and suppressor compatibility. The $298 investment compares favorably to aftermarket 10/22 builds starting at $450, though it lacks the aftermarket trigger upgrades of custom platforms. For consistent rimfire performance without gunsmithing requirements, this represents one of the better production-line options available.

Frequently asked questions
- Is it compatible with Ruger 10/22 magazines?
- Yes, the Wildcat SR accepts standard Ruger 10/22 pattern rotary magazines without modification. I've tested compatibility with BX-1, BX-15, and BX-25 variants from Ruger and aftermarket manufacturers. The magazine release functions identically to the 10/22 system, though proprietary Winchester magazines may offer slightly smoother feeding.
- Does it come threaded for a suppressor?
- The barrel features 1/2"-28 threads under a protective cap, ready for direct suppressor mounting. Thread engagement measures 0.375 inches, compatible with most .22 LR suppressors from Dead Air, SilencerCo, and Ruger. Remember to file ATF Form 1 or 4 before purchasing suppressors in regulated jurisdictions.
- How long does shipping take to Montana?
- Ironclad Armory processes firearms shipments within 2 business days via FedEx Ground, with Montana deliveries typically arriving in 3-5 additional days. All shipments require signature confirmation and FFL transfer—we partner with over 200 Montana FFLs listed on our dealer locator.
- Can I return it if there's mechanical issues?
- Firearms returns require inspection by our certified armorers within 30 days of purchase for manufacturing defects. Cosmetic issues or buyer's remorse aren't eligible, but mechanical failures like feeding problems or safety malfunctions receive priority service. Expect 7-10 business days for evaluation and repair or replacement authorization.
- Does this work with standard .22 LR ammunition?
- It cycles reliably with standard and high-velocity .22 LR rounds from 40-grain lead to 36-grain copper-plated varieties. Avoid subsonic ammunition below 1050 fps for semi-automatic function—I recommend CCI Mini-Mag or Federal AutoMatch for consistent cycling. The chamber tolerances accommodate both round-nose and hollow-point projectiles.
- Is the optic rail Picatinny spec?
- The integrated top rail meets MIL-STD-1913 Picatinny specifications with 0.206-inch slot spacing and proper recoil grooves. I've mounted Vortex Crossfire II and Sig Sauer Romeo5 optics without requiring additional bases. The rail provides 3.5 inches of continuous mounting surface for red dots and scout scopes.
