I've been toying with the idea and decided that there's no point in producing a hook like this one for HFT - it would be a disadvantage rather than an advantage.
But - I do have an idea for a design that will be both UKAHFT legal and actually a useful thing to have.
I don't want to produce something that offers no benefit or something that you can get by just fitting a MEC butt plate. If I do it, I want to offer something else that no other butt plate offers.
Going to talk to a few people over the weekend to see if my idea holds water or not.
