About this product
The Winchester Wildcat 22 LR 18-inch 10rd semi-auto rifle is a full-size .22 LR rimfire platform built for repetitive, low-cost training and small-game work, pairing an 18-inch precision-rifled barrel with a lightweight skeletonized stock and integral optic rail. It uses a 10-round rotary magazine and features ambidextrous controls with a focus on user-friendly maintenance, making it a direct descendant of the classic rimfire trainer philosophy. At an unloaded weight of 4 pounds and a price point under $260, it occupies a specific niche between bare-bones plinkers and match-grade target rifles.
What is the Winchester Wildcat 22 LR used for?
The Wildcat is primarily engineered for high-volume rimfire training, new shooter introduction, and small-game hunting within 75 yards. Its 1:16 twist barrel is optimized for standard and high-velocity 40-grain .22 LR rounds, while the 10-round rotary-magazine system prioritizes reliable feeding over capacity. The field-strippable design allows for a complete bolt cleaning in under 90 seconds without tools, a critical feature for the carbon-fouling-prone .22 LR cartridge.
How does the Winchester Wildcat compare to the Ruger 10/22?
The Winchester Wildcat offers superior ease of maintenance and a slightly lighter overall package at 4 pounds compared to a standard Ruger 10/22 Carbine's 5 pounds, but it cedes aftermarket support and magazine commonality. Where the 10/22 has a decades-deep ecosystem of stocks, triggers, and accessories, the Wildcat's design is more closed, favoring its out-of-the-box feature set like the built-in Picatinny rail and ambi controls. For a shooter prioritizing a low-cost, ready-to-run rifle with modern ergonomics, the Wildcat is better; for a builder planning extensive customization, the Stevens 334 platform or the Ruger is the correct starting point.
What does it weigh and what are the dimensions?
The rifle has an unloaded weight of 4 pounds (64 ounces or 1.81 kg) and an overall length of 37.5 inches. The 18-inch barrel contributes to this length, providing a sight radius of 16.25 inches between the ghost-ring rear and ramped post front sight. The receiver's integral Picatinny rail section is 6.5 inches long, sufficient for most rimfire optics and red dots without needing a separate mount.
Who is this NOT for?
This rifle is not for precision benchrest competitors or hunters seeking a suppressed platform without modification. The 1:16 twist rate, while standard for .22 LR, struggles to stabilize heavier subsonic or match bullets over 50 grains consistently, and the barrel is not threaded from the factory, requiring a gunsmith's intervention for a suppressor mount. If your primary use case is formal target competition or integrally suppressed varmint control, a dedicated target rifle or a model like the Stevens 334 in .243 Win for longer ranges is a more appropriate tool.
What's in the box?
The rifle ships with one 10-round rotary magazine, a basic owner's manual, and a cable lock. Notably absent are any additional magazines or sight adjustment tools; the rear ghost-ring sight requires a 3/32-inch Allen key for windage and elevation, a tool most shooters will need to supply. The packaging is utilitarian, with the rifle secured in a closed-cell foam liner within a single-box design.
Is the Winchester Wildcat worth it at $256.99?
At $256.99, the Wildcat presents a strong value for its intended role as a dedicated trainer or first rifle, undercutting many comparable base-model semi-auto .22 LR rifles by $50 to $100. You are paying for the modern feature set—the skeletonized stock, integral rail, and tool-free takedown—rather than premium finishes or match-grade accuracy. For a shooter who values those features and plans to run several hundred rounds per range session, the investment is justified; if you simply want the cheapest possible .22 plinker, big-box store bolt-actions exist at a lower price point with fewer conveniences.

Frequently asked questions
- Is the barrel threaded for a suppressor?
- No, the 18-inch barrel is not threaded from the factory. The muzzle is crowned but lacks any threads, requiring a qualified gunsmith to thread it to 1/2x28 or another common pitch, which typically adds $100-$150 to the total cost and may affect warranty status.
- Does it work with Ruger 10/22 magazines?
- No, it does not. The Winchester Wildcat uses a proprietary 10-round rotary magazine. This is a deliberate design choice to enable the rear-barrel cleaning access and spring-assisted magazine ejection. Spare magazines are available directly from Winchester or through retailers like Brownells.
- Can the stock be adjusted for length of pull?
- No, the synthetic skeletonized stock is a fixed design with a length of pull of approximately 13.5 inches. While the buttpad is checkered for grip, there are no spacers or adjustable components. This is common in this price segment but limits fit for very small-statured or youth shooters without permanent modification.
- What optics mount directly to the rail?
- The integral top rail is a standard Picatinny/MIL-STD-1913 specification. Any optic with a corresponding Picatinny clamp or ring will mount securely. For a .22 LR, a 2-7x32mm rimfire scope or a micro red dot like the Vortex Venom are appropriate choices that will fit within the 6.5-inch rail length.
