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.
