I have a 7.62x39 and added the side mount rail and an open reflex type sight. The top rail is obviously off-center to the left. I've sighted it in at 50 yds and it holds true at 100 yds too. I expect some sort of parallax to cause the point of impact to eventually move further and further to the left as distances grow but in the distances that I've shot, it doesn't. I also expect the opposite as distances are nearer, but that hasn't been obvious either even down to 50ft. My question: The rifling is right-hand twist which will cause a rightward horizontal drift. Does the off-center
I know the subject has been touched on briefly, but does anyone here know at what range POSP scopes are set to be parallax-free? It'd be even better if anyone had any success in re-setting it to something more useful than either a parsec or micron. Is it even possible? I've seen that some commercial scopes' objective lens rings can be fudged a bit to move the parallax setting.
