Description
There is no shortage of semi-auto .22s out there, but the Wildcat SR does a few things the old standbys never figured out. Winchester built this one around a striker-fired action instead of a hammer, which gives you a quicker locktime and a lighter, cleaner trigger pull than most rimfires in its class. Add a hemispherical firing pin for more consistent rim strikes and you get a rifle that runs bulk ammo with fewer hiccups than you might expect at this weight and size.
Suppressor Ready Out of the Box
The SR in the name means the 16.5 inch precision button-rifled barrel comes threaded 1/2×28 from the factory, with a knurled thread protector installed for the days you run it bare. Screw on a can and this thing becomes a genuinely quiet backyard and small game rig, especially with subsonic loads. Sights are handled by a ramped post up front and an adjustable ghost ring in the rear, which is faster to pick up than traditional rimfire notch sights. If you want glass, the integral Picatinny rail on the polymer receiver takes care of that.
The Wildcat SR in the Field
At roughly four pounds with the Forged Carbon Gray hydrographic stock and gray Perma-Cote barrel finish, this rifle disappears on a sling. The skeletonized polymer stock has a steep grip angle that puts your finger right where it should be on the trigger, and the controls, including the magazine release, work from either side. The 10-round rotary magazine loads easily and locks the bolt open on the last round, and if you have a drawer full of 10/22 pattern mags, those drop right in too.
Cleanup Without the Headache
Anyone who has fought a dirty rimfire will appreciate this part. Push one button and the entire lower receiver assembly, trigger group and bolt included, drops free so you can clean the bore from the chamber end. No punches, no tiny screws, no cursing at a takedown pin. For plinking, new shooter training, or squirrel season, the Wildcat SR is a hard package to argue with.

Frequently Asked Questions
Does the Winchester Wildcat SR come with a suppressor?
No, the SR designation means suppressor ready, not suppressor included. The 16.5 inch barrel ships threaded 1/2×28 with a knurled thread protector installed, so most common rimfire cans will spin right on. With subsonic .22 LR and a suppressor, this rifle gets impressively quiet.
Will the Wildcat SR accept Ruger 10/22 magazines?
Yes, and that is one of its best tricks. The Wildcat runs its included 10-round rotary magazine and also accepts aftermarket magazines built for the 10/22 pattern. If you already own a stack of BX-style mags, they will work in this rifle.
How do you clean the Wildcat SR?
Press a single button and the entire lower receiver assembly drops out, taking the trigger group and bolt with it. That lets you clean the bore from the chamber end, which protects the muzzle crown and makes rimfire maintenance far less of a chore. No tools are needed for basic takedown.
Can I mount a scope or red dot on the Wildcat SR?
Yes. The polymer receiver has an integral Picatinny rail on top, so red dots and rimfire scopes mount without any extra bases. The factory ghost ring rear and ramped post front sights work well on their own if you prefer to keep it simple.
