| Ok like the title says. I am going to the range tomorrw to zero and quail. I can only zero at the 25m target. I have a TA31 issued and I am trying to remeber if I zero at 25m how far down is the round supposed to strike in the 25m target using the 300 post aimed at center mass? I did it with my other one but they took that one and gave it to antother unti who needed with out telling me. I was in the arms room today looking for the TM that would tell me but could not find one. |

You are making this way too hard. There is a dedicated ACOG Zero target and the standard M16 or M4 target you will use at 25m.
1) ACOG target: Put the tip of the chevron in the upper half and the lower half is marked with you bullet strike zone; plus the directions are printed on the target just like with the M4 iron sight zero target. Your POA is above your POI but both are marked on the target nice and clear. 3) M4 target: Use the tip of the BDC(300m mark) line like the pix shows to get both POA and POI. Either way at 25m just remember that your aim can be either the tip of the chevron or the tip of the 300m mark, BUT your POI will always be the tip of the 300m mark. Edit: Ref if you have time page 8-18, 8-19 of FM 3-22.9 (12 Aug 08) on ACOG zero. It is as above stated. Go thru AKO to find this reg. Have fun and clean up your brass. |

Hey thanks that is what I was thinking but could not remeber for sure or not. Yes I am shooting my issued M4 on a M4 25m zero target. It really pissed me off when I got issued my first ACOG and took the time and everything and piggy backed off another unit to go zero it. Then I go in to do a wipe down of my weapon and find that my ACOG was given up to another unit because they were short one. After I tore off in the armors ass about doing this I asked him why he did not get one of out of the conex that he still had here. He reason was that the new commander did not want him to go into the conex and take anything out as it is supposed to be going to Rear Detachment or something. 
Well I went and looked at some of the other weapons we had and found one sitting on a weapon that belonged to a NCO I had removed from PSD. I took it and now I have to go back to the range and rezero. I was looking at it and realized the dumb ass bottomed out the zero dials so now I am trying to figure out how far up i need to come up, that and how far right I need to came back to try and get the cheveron at least evened up so when I fire my weapon I will be on the paper.  Man it is going to b e a long day at the range in my damn IOTV and shit.

Is this dedicated target available online anywhere? I'd love to have a PDF of it... |

You will be very close to your 100m zero if you zero like that. Confirm at 100 and make any small adjustments. Below is the Trijicon supplied zero target when we got the TA31F. When you look thru your optic you will see that the 300m tip lines up just right in the "strike zone" when the tip of the chevron is in the "aiming point" zone.
