The innovative Winchester Wildcat Semi-Auto Rimfire Rifle is lightweight, reliable, and accurate, utilizing a striker-fired design for faster lock-time and lighter trigger-pull than hammer-driven firearms. The ergonomic, polymer stock features a Picatinny rail section under the forend, front and rear sling swivel studs, and a near-vertical pistol grip for improved control and comfort. The upper receiver assembly comes equipped with an aluminum 1913 Picatinny rail, while the lower receiver assembly drops out of the stock, with the push of a button, for easy cleaning and maintenance. A rear access receiver port allows you to clean the bore properly from the chamber for quick, convenient maintenance, and a ghost-ring rear sight and a post-style front sight provide rapid target acquisition. The chromoly steel barrel features precision button rifling and a recessed target-style crown for greater accuracy. Plus, the rotary 10-shot magazine functions reliably, and has a last-shot, bolt hold-open device. The Wildcat is also compatible with aftermarket 10/22 magazines.
