UPDATED 01 APR 2015 - Added AK-47 (7.62x39) 25 yard targets

I wanted to share some targets I created to assist in zeroing my red dot optics. I was always unsatisfied with using other targets to zero my red dot 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.

These targets are designed to take advantage of the human eye's natural tendency to center an object within a circle. Using these targets will save time and ammunition while at the same time providing tighter groups for a better zero.

The target is ‘calibrated’ for use at 50 yards to obtain the 50y/200m improved zero for the AR-15 rifle/carbine or a 50 yard zero for AK-47 variants.

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.

Example:

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.

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 Example:

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.

Example:

Adjusted 25 yard targets for a 300 yard zero

Same instructions as the adjusted 25 yard targets for a 50 yard zero, only these are calibrated to give a 300 yard zero. Again, be sure to confirm your zero at 300 yards given the chance.

Example:

Adjusted 25 yard targets for a 50 yard zero

Here are 25 yard targets that will give you a 50 yard zero when used properly when you only have access to a shorter range. These were made to work with low mount AK optics that allow co-witness (2.25" over the bore) using averaged 123gr 7.62x39mm velocities from a 16" barrel.

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 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.).

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:

Bump to keep the awesome going.

Thanks a bunch and your timing is impeccable - I just got my Aimpoint M4S and mount from Laure yesterday.

Good stuff.

I just updated the targets with a more bold black ring at the request of a few members here. Thanks for the comments

serious question, are you in the target industry?

not in the slightest... military / mechanical engineering student. I just had an idea that worked out pretty well.

Awesome, thank you! Would it be possible for you to make a 3 MOA version for the micros? I can definitely still use these though.

Please use one of the targets in the original post as the now cover multiple different MOA dots.
