"The Keystone Sporting Arms Crickett 6061 Precision Bolt-Action Rimfire Rifle is a manually cocking, single-shot chassis rifle with a 16.125"" carbon fiber-wrapped barrel. Carbon fiber-wrapped barrels are lighter, more rigid, and faster in dissipating heat than standard steel barrels, providing enhanced accuracy with less unnecessary weight. The barrel is threaded to accept a suppressor and comes with a thread cap. The 6061 aluminum chassis provides a strong foundation for accuracy and accepts AR-style pistol grips and stocks. The included adjustable stock provides simple length-of-pull adjustments to fit a wide range of shooters. 4.5-lb. trigger provides a crisp break and fast reset. Underside Picatinny rail for accessories. Receiver is drilled and tapped for Crickett scope mounts. Adjustable rear peep sight and fixed front sight.
