Thanks guys, and many thanks for trying, Norm.

Just for now, I'll order some M7x70mm hex bolts, and I'm sure I can 'dremel' a slot in one for a screwdriver.

Yes, it's a bit of a thing this M7 business... anybody with a custom shape stock and an HW95, 80, 77 MK1, etc - could be in the same boat...

... HW77, there's a thought... the ABT lug from a Mk2+ '77/97 is 7mm on the one end...

No no, it's way too complicated to think about this side of Christmas!
