Been using these for a couple of months now and am really impressed. The design is great, build quality is great and there's loads of adjustment. Really comfy too. The hook fits a wide range of rifles and the following fits loads of different hooks. Both Brian and Andras are great blokes and a real pleasure to deal with. Highly recommended. http://www.competitionshooter.co.uk http://www.maestro-design.co.uk Brian's hook with FolloWing Brian's hook on its own.
