Description
Winchester took a fresh look at what a .22 autoloader should be when they built the Wildcat, and the SR version adds the one thing a lot of rimfire fans ask for first: a threaded muzzle. The 16.5 inch button-rifled barrel wears standard 1/2×28 threads with a knurled protector installed, so it will accept most rimfire cans without any extra hardware. At right around 4 pounds, this rifle carries all day without complaint, and the OD Green skeletonized stock with the matte black receiver gives it a sharp, modern look that sets it apart from the usual sea of black rimfires.
What Makes the Wildcat SR Different
The standout feature here is the drop-out lower receiver. Press one button and the entire trigger group, bolt, and guide rails come out as a single unit, which turns cleaning day into a five minute job instead of a chore. Controls are fully ambidextrous, including the magazine release, and the safety button is reversible for lefties. The striker-fired design keeps the action simple and consistent, and the 10 round rotary magazine locks the bolt open on the last round with spring-assisted ejection that pops the mag right into your hand. Here is a bonus a lot of folks miss: the Wildcat also runs 10/22 pattern magazines, so if you already have a drawer full of those, they will feed right through this rifle.
Sights, Optics, and Field Setup
Out of the box you get a fully adjustable ghost ring rear sight paired with a ramped post up front, a fast and forgiving combo for plinking and squirrel woods alike. When you are ready for glass, the integral Picatinny rail on top of the receiver handles red dots and scopes without buying a separate base. There is a second rail section under the forearm with an included cover for a light or bipod, plus front and rear sling eyelets for carry in the field.
Why the Wildcat SR Earns Its Spot
Between the suppressor-ready barrel, dead-simple maintenance, and magazine flexibility, this is a .22 that works as hard as a trainer, a small game rifle, or a quiet afternoon plinker. It is a lot of thoughtful engineering packed into a light, handy package.

Frequently Asked Questions
Will the Wildcat SR accept Ruger 10/22 magazines?
Yes, and that is one of its best tricks. The Wildcat feeds from standard 10/22 pattern magazines in addition to its included rotary mag, so aftermarket options are everywhere. The factory 10 round rotary magazine also locks the bolt open on the last round, which most 10/22 mags do not do.
What thread pitch is the barrel, and does it come with a thread protector?
The muzzle is threaded 1/2×28, which is the standard pitch for rimfire suppressors and most .22 muzzle devices. A knurled thread protector comes installed from the factory to keep the threads clean when you are running it bare. No adapters needed for most rimfire cans.
How hard is the Wildcat SR to clean?
It is one of the easiest rimfire rifles out there to maintain. Push a single button and the entire lower receiver assembly drops out with the trigger group and bolt as one unit, no tools required. You also get rear barrel access, so you can clean from the breech instead of running a rod through the muzzle.
Can I mount a scope or red dot without buying a rail?
Yes. The Picatinny rail is molded right into the top of the receiver, so optics bolt straight on. There is also a short rail section under the forearm for a light or bipod, and it ships with a cover to keep it snag-free when not in use.
