so, finally got all my parts in on my newest AR. I'm going for "how cheap can I do an AR" on this one. So far, I have about $600 invested into this, to include $300 I spent on an Aimpoint Comp A3 red dot that I got on clearance. Plumb Crazy lower DSA upper Aimpoint optic anyway, it all arrived after waiting 5 months on the DSA upper. (every time I called them, they had a different story on why it was delayed, I would have cancelled the order completely, but I wasn't in any real rush, and my goal was budget) I haven't fired it yet so it's not sighted in at all. I noticed my red dot comes in at about where the base of the A-frame is, and the front sight post would block my sight picture with the red dot. I know there's a chance that the front post is a little high, but it doesn't look that much higher than on my other AR that is sighted in, and the red dot was advertised as coming in "already zeroed" The red dot appears in the exact center of the optic, it's just that the center of the optic seems to sit a little low compared to the front sight post. Looking at pictures, the mount on my optic looks identical to the one on the weapon I carried while deployed, and I don't remember that one being "off center" nor did the front post block sight picture of the red dot. just wondered if this was normal, or if I need to look into trying to raise the optic a small amount? what have you guys encountered with new weapons and sight alignments?
