    NVG riser zero?

    Iím not new to shooting, but ARís are not 2nd nature to me.

    Iíve 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. AnywayÖ.

    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. Iím just wondering what yíallís insight on this topic.

    Iím curious what others will say. My PCC is currently zeroed at 25y and Iíve done both 20 and 50 before. I think it depends on the furthest shot and the size of the target.

    Iím using a NV height mount now too and there is a a bit more offset at close range. It is more comfortable to shoot.

    Your answer is right in your post. What allows you to perform most effectively.

    As for zero, I prefer the repeats like the 50/200 meter zero or 36/300 yards zero.

    https://www.pewpewtactical.com/best-...tlesight-zero/

    From there you can commit offsets like 25m, 100m and 25 yards, 100 yards to memory and adjust accordingly at those ranges.

    My go-to carbine has a 1.93" LPVO mount, I have a 2.02" G mount I haven't tried yet due to lack of optic. My next Aimpoint Micro mount will the Unity Tactical 2.26" FAST. So yeah I like tall mounts, but my SPR has 1.57" which is better for shooting prone or off the bench.

    I think as optics progress, there will be programmable dots that compensate for you. Example: 200-100-25-10.

    Optics directly tied to the bore that only they can see.

    Of course that the future. Iím just going to book some time on a range to experiment

    I like to keep my firearms and optics as "mechanical" as possible.

    Heres my rundown and what I've found works best for me and what works for my intended use for my AR as a general purpose rifle. I utilize an 8" maximum point blank range for all of my rifles unless they have a specific zero specified by the reticle, IE a bdc reticle such as the vortex JM-1 bdc thats on my main 14.5 rifle right now, and I used a ballistic calculator and live fire verification to make sure that the bdc reticle lines up to my particular rifle and ammo. 8" maximum point blank range ( shortened to MPBR after this ) is the bullets impact from the muzzle to " x " range within a 8 inch impact zone. IE 4 inches high, 4 inches low. For example, an m4 carbine with an aimpoint mounted in a 1.5 height mount on the upper receiver, firing m855a1, zeroed 1 inch low at 25 yards will be within an 8 inch impact zone out to 330 yards. What this does is from 0 to 330 yards I do not need to hold for bullet drop to get a good hit on a deer, or other " critter " beyond 330 I use holds, for cqb distances its just compensating for the height over bore. I've found this works very well for most general purpose, home defense, and hunting uses. Its really easy to do as well. You just need height over bore, muzzle velocity, ballistic coefficient for the particular round you're using and a good calculator ( i use the one on the berger website as its super simple ) quick example of how to calculate height over bore on an AR, height from center bore to top of receiver is 1.215, then add the height over your mount, 1.5, 1.93 etc. Then take those two numbers, add them together and you have your height over bore to enter into your ballistic calculator. hope I explained that well and if you have any questions just ask!

    Good info above.

    If your longest engagement is 100yds, you might be happy trying that first, though. For the 5.56 gun.

    There was a recent discussion about PCC zeros you can look at. https://www.m4carbine.net/showthread.php?237028-Best-zero-for-9mm-PCC
