How much does the rear sight need to move for 1 MOA?

How much does the front sight need to move for 1 MOA?

In decimal inches please.

Thanks!

Technically speaking, it depends upon the sight radius of your rifle/carbine.

Practically speaking, who cares. Just adjust it until the POI is where you want it.

That's a good link, BTW.

Good luck.

Sorry I didnt add the sight radius, I know it is important, just forgot.

Parctically speaking, I care. That is why I asked.

But thanks for the opinion, BTW.

Sorry. I wasn't trying to be flip. I'm curious about things myself, so I ran off a couple of quick calculations.

My A1 carbine has a sight radius of 14 15/32". So moving either the front or rear sight by approximately .0048" would equal a 1 MOA shift in the POI.

LOL. I might be if I did the calculations right the first time. See the edited version above. I should stop trying to watch football and calculate at the same time.

I think I got it right now...

You must have been watching the replay of the Colts. Probably why you came up a bit short.

Thanks!

Damn, we are dealing with small numbers here. Depending on how I attack the calculation, and how my calculator rounds off the numbers, I get some variation in the answer. Let's split the difference, and call it .0048".

I'm done....
