I have for sale a CZ457 at one in a Boyds pro varmint stock, has a threaded 16 barrel, 6-24x50 first focal plane scope, area 419 50moa rail, and has been headspaced for CCI green tag or CCI standard velocity target. It will come with other head spacing shims. This rifle is very accurate and shoots sub-moa groups with CCI standard target ammo that you can get from anywhere. Ive lost interest in competitions but regularly shoot out to 550 yards with it.
