    Arrow Zero Targets Optimized for Red Dot Style Optics (Aimpoint, EOTech, etc...)

    I wanted to share some targets I created to assist in zeroing my Aimpoint optics. I was always unsatisfied with using other targets to zero my Aimpoints as I felt as if I was guessing whether or not to dot was correctly centered over the target. I created these to address my concerns and they have worked quite well and definitely speed up the zeroing process. I also have shot tighter groups using these targets.

    The targets are ‘calibrated’ for use at 50 yards to obtain the 50y/200m improved zero.


    The target consists of:
    • 1 MOA center ‘zero’ dot
    • 2 MOA green inner dot to correspond with 2 MOA optics
    • 4 MOA red outer dot to correspond with 4 MOA optics
    • Larger black ring to assist in centering the optic’s dot over the center of the target.
    • Bold gray cross-hairs to assist in centering the reticule on the target.
    • Grid lines with click adjustment references and adjustment dial references



    When the target is correctly placed at 50 yards, the optics dot will completely cover the colored portion of the corresponding target. The black ring will assist in correctly centering the optic over the target for a near perfect hold (depending on if you do your part). Just shoot your groups and use the adjustment references to quickly move your point of impact. This should speed up the zeroing process and provide an extremely accurate zero at the same time.


    Examples:



    Download the target in .pdf format HERE

    Just make sure your printer scaling is set to NONE / ACTUAL SIZE and you should be good to go.

    I hope this can be useful to others.

    I've also created a version without the large assisting ring.

    Adjusted 25 yard targets for a 50 yard zero

    Here are 25 yard targets that will give you a 50/200 yard zero when used properly when you only have access to a shorter range. These were made to work with standard AR sight height (2.6" - 2.8" over the bore) using averaged M193 / M855 velocities from a 16" barrel. These should also help those using different rifle setups (barrel length) and/or heavier grain bullets get close.

    Place the target at 25 yards. Your point of aim should be at the colored / bold outlined portion of the target. Fire your group. Adjust the point of impact to the GRAY DOT in the middle of the target. If you follow the adjustment grid it will get you there. The math works out to give you a 50/200 yard zero.

    Be careful to keep the optic's dot centered within the optic itself as much as possible when zeroing at this range as it is not entirely parallax free at 25 yards. Also, be sure to verify this at 50 yards when you can as there may be slight differences in each weapon that may alter the zero (sight over bore height, co-witness, barrel length, ammunition used, etc.).

    25 Yard Target Examples:



    The Aimpoint 25 yard - 50/200 yard zero target in .pdf can be downloaded HERE



    Adjusted 25 yard targets for a 100 yard zero

    Same instructions as the adjusted 25 yard targets for a 50 yard zero, only these are calibrated to give a 100 yard zero. Again, be sure to confirm your zero at 100 yards given the chance.

    Examples:



    The 25 yard - 100 yard zero target in .pdf can be downloaded HERE


    I encourage anyone who uses these to leave feedback in this thread for future improvements or suggestions. If there are any other targets you'd like to see (different calibers / loads) let me know and I'll will work something up.


    Also check out these targets 25M improved zero targets I created based of the common US Military Zero target. They have adjusted zeros for 50/200M, 100M, and the standard 300M zero:

    What has your feedback been on how close the "50 at 25" zero targets have been?

    Awesome post, bookmarked (sticky?)

    They have been dead on for me and others who have used them reported the same.

    I tested them transitioning between the 25 yard target placed at 25 yards and the 50 yard target at the correct 50 yards during the same string. POI's fell within the adjusted gray portion of the 25 yard target and also within the red portion of the 50 yard target.

    This was with both XM193 and XM855 out of a 16" barrel. The only issue I see is using different ammunition with different ballistics. I don't think it would be too far off though.

    This looks outstanding. Definitely going to give these a try. What do you imagine the difference would be on the 75 grain stuff like.Hornady T2?

    I just threw the data from Hornady's site in my ballistics app and it looks like the 75 grain T2 TAP round will impact -1.1" @ 25 yards for a 50 yard zero. This is with a muzzle velocity of 2660 fps. The adjusted 25 yard / 50 yard zero targets above have the adjusted POI dot at -1.2", so they should get you really close. Maybe just adjust your POI slightly lower on the 25 yard adjusted target.

    Also, the 50 yard zero will also yield a 50/180ish yard zero using 75g T2 instead of the common 50/200 yard zero that you get with 55 / 62grain loads.

    Interesting....I am working on zeroing my T-1 in (better than it is currently zeroed) and this looks worth trying. Just to make sure when printing this, with scaling on NONE, is this to be printed on 8.5x11?

    Correct, these are intended to be used with standard 8.5x11" paper. For verification, the numbered grid lines are spaced at 1/2".

    Thanks again for posting these. I've used them several times lately.

    This looks good, thank you. I will be using this after I get a 2 MOA T-1!

    Just used the 25 to 50 target a few days ago, thank you! I was using Federal XM193 and then confirmed with Speer GD 64 grain; it seemed pretty spot on. I only had to do a one click adjustment when I checked at 50.

    These targets are GTG and very useful. I prefer the red to the green. Thanks for making these available.

    Just wanted to post this up so everyone can see that the 25 yard targets are calibrated correctly to give you a 50 yard zero with M193 / M855.




    Ammunition used was IMI M855 out of a 16" barrel using a Comp ML2 with a 4MOA dot.

    Three rounds in the 25 yard target, adjusted POI one click left, then confirmed with five rounds in the 50 yard target (not my best group, but I'm blaming the wind giving my contacts a hard time).

    I zeroed my irons and red dot yesterday using your targets. Big thanks to you for making these great tools.
