Description
Winchester has been building rimfires for well over a century, but the Wildcat is a different animal entirely. Instead of the usual hammer-fired setup you find on most .22 autoloaders, this one uses a striker-fired action with a faster lock time and a lighter, cleaner trigger pull. A hemispherical firing pin helps with ignition consistency, which matters more than people think when you feed a rimfire a steady diet of bulk ammo. The 18 inch button-rifled barrel wears a recessed target crown, and this version pairs a matte black barrel and receiver with a lightweight OD green skeletonized polymer stock that keeps the whole rifle around four pounds.
Cleaning the Wildcat Without the Headache
Anyone who has scrubbed a filthy rimfire action knows the pain of fiddly takedown. Winchester solved that with a lower receiver assembly that drops out by pressing a single button, no tools required. That opens up rear barrel access so you can clean the bore from the chamber end, the way it should be done. When it comes time to pull the stock or adjust the sights, the included pair of Allen wrenches handles both jobs.
Magazine and Sights That Make Sense
The 10-round rotary magazine loads easily and holds the bolt open after the last round, a feature you rarely see at this price point. Even better, the Wildcat accepts 10/22 pattern magazines, so if you already have a drawer full of them, they will feed right through this rifle too. Up top, a ghost ring rear sight pairs with a ramped post front for quick, natural aiming, and the integral Picatinny rail is ready for a red dot or scout scope whenever you want glass. There is a second rail section under the forearm with a cover, plus front and rear sling eyelets for carrying it into the field.
A Wildcat Built for Real Work and Real Fun
Ambidextrous controls, including a reversible safety button, make this a smart pick for lefties or for teaching new shooters of either persuasion. Whether it earns its keep on squirrels, spends weekends knocking over tin cans, or serves as a low-cost trainer, this is a whole lot of rifle for the money.

Frequently Asked Questions
Does the Winchester Wildcat accept Ruger 10/22 magazines?
Yes, and that is one of its best tricks. The Wildcat runs both its included 10-round rotary magazine and standard 10/22 pattern mags, so if you already own a stack of them, they will work in this rifle. That makes stocking up on spares cheap and easy.
How do you clean the Wildcat 22?
Press a single button and the entire lower receiver assembly drops free, no tools needed. That gives you rear access to the barrel so you can run a rod or bore snake from the chamber end, which protects the crown and makes rimfire gunk much easier to deal with. It is one of the simplest cleanup routines of any semi-auto .22 out there.
Can I mount a scope or red dot on the Winchester Wildcat?
Yes. The receiver has an integral Picatinny rail molded right in, so a red dot or rimfire scope bolts on without buying a separate base. There is also a short rail section under the forearm with a cover included for lights or a bipod adapter.
Is the Wildcat a good first rifle for new or left-handed users?
It is a great fit for both. The controls are ambidextrous, including a reversible safety button, and the whole rifle weighs right around four pounds, so smaller-framed folks handle it comfortably. Soft .22 LR recoil and a light striker-fired trigger make it easy to learn good fundamentals on.
