Winchester Repeating Arms Wildcat, Semi-automatic Rifle, 22 LR, 18 Sporter Contour Barrel, 1:16 Twist, Blued Finish, Black, Olive Drab Green, Composite Stock, Rear Ghost Ring Sight, 10 Rounds, 1 Magazine 521139102 The Wildcat doesn't just look different, it is different. Through the extensive use of tough polymers and modern design principles, the Wildcat has a number of features you just don't see with other rifles. Like a centerfire rifle, the Wildcat is a striker-fired design - not hammer fired - for improved trigger performance with faster locktime and a lighter pull weight. A hemispherical firing pin offers improved reliability with rimfire ammunition. The Wildcat also features a durable, 10-round polymer magazine. The rotary design is reliable, easy to load and has a bolt stop that locks the bolt back after the last round has been fired. The Wildcat also accepts magazines that fit 10/22 rifles.
