On the older Anschutz thumbhole stocks, they do not come with a cheek adjuster. The below adaptation solves the problem of not having an adjustable cheekpiece. This cheekpiece is adjustable for front & rear tilt, cast on & cast off, and cheek height. It can also be adapted to the thumbhole stocks that have the cheek riser, but are difficult to use.
