Winchester Repeating Arms 521159102 Wildcat SR 22 LR 10+1 16.50″ Flat Dark Earth Threaded Barrel, Flat Dark Earth Picatinny Rail Polymer Receiver, Adj Cheek Piece & LOP OD Green Synthetic Stock

The Winchester Repeating Arms 521159102 Wildcat SR 22 LR 10+1 16.50″ Flat Dark Earth Threaded Barrel, Flat Dark Earth Picatinny Rail Polymer Receiver, Adj Cheek Piece & LOP OD Green Synthetic Stock is a modern autoloader built for the shooter who demands rimfire performance without the legacy weight. Weighing just 4 pounds, this rifle combines a lightweight OD Green composite stock with a Flat Dark Earth Perma-Cote finish on the barrel and receiver. The 16.50″ threaded muzzle is suppressor-ready, and the 10-round rotary magazine includes a last-round bolt hold-open. It also accepts aftermarket 10/22 magazines, giving you flexibility at the range or in the field.

Key Features

• Threaded Muzzle & 16.50″ Barrel — The factory-threaded barrel (1/2×28 TPI) allows direct suppressor mounting, reducing report and recoil for quieter, more controlled shooting. Why it matters: It turns a plinker into a versatile tool for training, pest control, or backyard practice.
• Adjustable Cheek Piece & Length of Pull (LOP) — The OD Green synthetic stock features a tool-free adjustable cheek piece and LOP, letting you customize fit for different shooters or shooting positions. Why it matters: Proper ergonomics improve accuracy and reduce fatigue during long sessions.
• Last-Round Bolt Hold-Open — The 10-round rotary magazine locks the bolt rearward after the final round, giving you a visual and tactile cue that the gun is empty. Why it matters: It simplifies reload drills and keeps the action open for safe handling.
• Flat Dark Earth Picatinny Rail — The receiver is topped with a full-length Picatinny rail, ready for optics, red dots, or backup iron sights. Why it matters: No adapter needed—mount your preferred sight system directly, improving acquisition speed and accuracy.
• Lightweight OD Green Composite Construction — At only 4 pounds, the Wildcat SR is easy to carry all day and quick to shoulder. Why it matters: Lighter weight means less fatigue on the move, making it ideal for youth shooters, hikers, or anyone who values portability.

Who It’s For

This rifle is for the rimfire enthusiast who appreciates modern upgrades—threaded barrel, adjustable stock, and a Picatinny rail—in a package that respects Winchester’s legacy. It suits collectors who want a lightweight suppressor host, plinkers who shoot hundreds of rounds per session, and hunters who need a reliable .22 LR for small game. The adjustable stock also makes it a strong choice for introducing new shooters to semiauto rifles.

Pros & Cons

• Pros: Suppressor-ready from the factory; accepts aftermarket 10/22 magazines; fully adjustable stock; incredibly lightweight (4 lbs); Perma-Cote finish resists wear.
• Cons: The polymer receiver may feel less premium to some shooters accustomed to all-steel construction; the rotary magazine, while reliable, can be slower to load than a stick mag.

Comparison

The Wildcat SR outshines the Ruger 10/22 Carbine in weight and adjustability, while matching the M&P15-22 on barrel threading. Its ability to accept aftermarket 10/22 magazines gives it an edge in parts availability, though the M&P15-22 offers a more AR-like manual of arms.
