Is that chart for a 25 yard zero? Thank you

It is. You’re welcome.

I would zero a Mk18/SBR for 50, rather than 25. 100yd would be okay too. Too much going on with a 25.

25yd zeros are for SMGs/PCCs and pistols with RDSs.

I agree. My preference is a 50 / 200 yard zero with an emphasis on the 200 for my 5.56 AR 11.5 SBR & 10.3 pistol. I see no benefit to a 25 yard zero on the OPs gun.

Also recommend 50.

Alright based off of that information do you think that a 25 yard zero is a good set up for a gun like that that will be used mostly for just up close?

Optimal zero distances for 10.3" or longer barrel 5.56 are 50, 100, or 200 yards/meters with point of aim coinciding with point of impact (POA=POI).
You can get away with zeroing with POI 1.5" or so below POA at 25 to get in the area needed for being closer when moving back to 50/100/200, but it's always best practice to confirm at longer range if you actually want to have the ability to precisely place shots at those distances.
The 100 yard zero is actually better for close range as it has a more consistent point of aim for acceptable shot placement due to the more gentle ballistic rise to line of sight.

Jack’s link posted above is a very good one to read. It is the same zeroing philosophy I was taught in the team leader’s course, for the same reasons.

Using the same range of data I played with earlier, with a 100yd zero you should be hitting ~1.35” low at 25. A 50yd zero should be ~1.08” low at 25.

As said before, you have to shoot it to confirm.

If you search around there was a company that provided targets for different optics and zero ranges. For example, they would have a 25yrd zero point that you would aim at and a separate zero spot for where your rounds should hit. I’ll look for them and post here. I tried them with a rifle I had already zeroed and it worked pretty well.


Here you go. Due to your ranges limited yardage it might help until you can get to a 50yrd range.
