CZ USA 457 22 Long Rifle Scout Blued Bolt Action Rifle - 16.5in - Built to be an ideal first gun for young shooters, the Scout has a short 12in length of pull. With simple leaf rear sight and blade front (rear adjustable for windage, front for elevation), 11mm dovetails on the receiver make adding a scope a breeze. The 457 Scouts have a muzzle that's threaded 1/2x28, allowing for hearing-safe shooting without the need for muffs or plugs. Adding a larger stock is easy once kids outgrow the short length of pull, as all 457's use the same stock inletting (with two barrel channels specific to standard and varmint-weight barrels). The entire 457 platform is modular, meaning swapping different barrels/chamberings, or stocks is done quickly and easily with only a few tools. Shipped with a single shot adapter to teach ammo conservation, any 457/455 magazine will fit, from 5 to 25 rounds.
