I’m not new to shooting, but AR’s are not 2nd nature to me.

I’ve had an AR and 9mm PCC for a few years now. Not much action due to the shortage. I have recently dove into the high rise optic world. Not for NVG, but for body ergonomics. Keeping the head more upright (like pistol shooting) just seems logical. Anyway….

Im wondering who has experience/insight on a good zero. Im not looking to engage threats past 100y. The role will be HD and immediate threats.

I understand hold-over and height over bore. I’m just wondering what y’all’s insight on this topic.

I zero the same way and at the same distance that I'd zero for a "normal" height carbine. For me that's 50 yards. Nothing magical about adding a riser from that perspective.

The hold is just something you'll need to account for and stops being a serious issue once you're getting much past 40-50 yards anyways.

The BZO needs to correspond to the cartridge.  .223/5.56 works best with a 50yd or 100yd BZO.  PCCs work best with a 25yd or 50yd.  7.62x39 works best with 25yd or 50yd.
