Buckstix, please explain the rear sight. 300 and 079. Plus a middle standing leaf I believe. I don't think I've seen two opposing leaves like this before with a central standing leaf.

What do the 300 and 079 stand for, 300 metres and 79 metres? 79? What's on the other side of the leaf?

What distance is the standing leaf for? I would guess 100 m. The "079" 200 m. And the 300, 300 m.

Thanks.
