Open Sight Question

[Bison]

On standard AR A2 sights . . . do the two rings have anything to do with hold over? That is, is the smaller (long range) ring situated higher as to raise the point of impact of the bullet or is the smaller ring just that, smaller, to assist with zeroing in on a far away target. I know, basic quesiton. Thanks in advance for your response.

Most are different height.

You can get same plane rear apertures though.

[Robb Jensen]

Yes stock/OEM A2 rear sights are on different planes.

You can buy aftermarket apertures that are on the same plane.

Thanks fellas. What about the Troy flip up rear sights? Anyone know if they are on the same plane or not?

[Bison]

Nevermind. I just looked at their website and it pretty much lays that out plain as day. Thanks anyway.
