Hi everyone , I have a A.R.M.S 40L Rear sight and a Samson flip-up front sight on my SIG 556, which aperture do I use to Zero at 50 yards, the small hole one or the big hole one? Yes I know it is a AR 15 forum, I do own a M4 Also. Any way info will help. Thanks

Typically you use the large aperature to zero in.

I use the small ap to zero at 50Y
I have the arms 40Lsp / LMT M4

I have a ARMS 40 regular on my spare LMT M4
I zero at 50 with small ap

suppose to zero the regular arms 40 at 25M
also the APS arent on a same plane

My understanding has always been the small ap is the real aiming ap and the larger ap is the combat or promask ap with more margin of error but larger Field of view.
