(that's from my RO book)
Don't see any mention of sights so it must be open for peeps or open adjustable iron.
Now the key is those sticks don't have to be hinged in the middle, most don't, they set them to a proper height for a seated position. I've seen guy's with the hinge (aka; small bolt) anywhare from 4-10" from the non pointed end. See lot's of 1x2 pine and shorter than the 40"s.
I've always wondered why the rule book isn't on-line? Must be cause' they sell'm or something?
p.s. The reason for shooting 2 at one side and 3 at the other is because that X ring disappears pretty fast. 2 in the X and one next too those in the 10 for a clover and the 4th-5th shots could go through that hole! 1"-1 1/2" groups are the norm at 50 yards.
