How well do the cocking piece sights work in real life? Do you have trouble maintaining zero? Do you have to watch out for your eye relief?They look really neat that's for sure.Are they available any more?
There has been a lot of bad press over the years about cocking piece sights but I like them. They are hunting sights and as such work just fine. One summer I took my 1903 Niedner heavy barrel target rife which has a Lyman 48 and shot a couple groups with it then removed the 48 and used both a No.1 and a No. 103 I did not try to move the groups just fired away and both cocking piece sights gave about the same size groups as the 48. Once the rifle is cocked don't touch the sight and they seem to work fine. There is a well known picture somewhere showing a man with 1903 and cocking piece sight with the rifle in the cocked position showing how close to the eye it was making it dangerous. I would not recommend one if you where shooting in the prone position.
I like the Rigby sight, I have one a Kirkwood Bros 1903 that was made by Niedner.
