I have the ARMS 40a2 rear flip up sight. It has two apertures, one large, one small. I have been using the large aperture for 50 yards. Here is my problem....
Re-zeroed the sight yesterday at 50 yards, shot a baseball sized group of about 20 rounds.
Moved target out to 100 yards and it's shooting a good 5-6 inches high? Hmm, shouldn't it be shooting low if anything? Or hell, should still be right on target considering how flat the trajectory is.
Checked my sights, notice that my front post is turned WAY up. It's so high it can wiggle pretty easily, like a bolt that is only being held in with one or two threads, that is how it feels. I don't think this is right because to lower my group at 100 yards I would have to unscrew it even more.
Also, when I look through the apatures I can see much more than just a verticle post, the part of the front post that is tapered as well as the base are visible in my sight picture, is this wrong? I thought you take the post and put it in the center of the apature and sqeeze the trigger, should I be able to see my entire FSB when I'm shooting?
Sorry for the number of questions this is just ticking me off, first military style irons I've ever used and it's becomming frustrating.
