Do you remember how many rounds it took you to zero your red dot? I’m going this afternoon to try it at 50 yards. Hopefully won’t need over 20 rounds?
It took me about 50 rds, BUT it was the very first time I had zeroed a red dot optic. YMMV.
If you start at 25 yards and sight it in so it hits a couple inches low, you’ll make your task much easier
What I like about the AR platform and bolt action rifles is the ease of getting sighted in quicker.
On the AR separate the upper and lower and remove the bcg.
On a steady table and a good bag or rest look down the bore and center the target.
Just lift your head a bit to see the dot and adjust to line it up.
The farther your eye is from the end of the receiver the more accurate you can be cause you can just get a bit of light around the black bull.
Put it together and fire it.
If you were careful, you will be very close and not waste as much ammo.
Works good with a bolt action also.
Been doing it this way for years to get on paper so not to waste ammo.

This.
If your irons are good, and you’ve zeroed the dot to your irons, then you can expect to only need a handful of rounds.
I recently did this with my BCM and H1. Started at 25 using an Aimpoint target (quite helpful for accurate adjustments) and the H1 zeroed to the irons. Took a shot, checked, and adjusted. Took another shot, it was slightly off. Made a final adjustment, and it seemed to be on, so I took a 5 shot group. That was good too. 8 rounds were used. Then I went about my day verifying at different ranges and playing with different elevations.
If you aren’t positive in your fundamentals, you might find yourself chasing a hole, especially at 50 yards. I would strongly recommend taking a 3 shot group before you adjust, if you’re not sure you’re making a good shot. If that’s the case, 20 will still get it done. But remember… a 50 yard zero is ONLY a 50 yard zero, unless you go and verify at longer ranges. A good zero is crucial, so make sure you do it right.
^^^ What he said. And I’ll add… Sight in at a known distance and know the value of the adjustments at THAT distance. Use or make a target that the center ring is a slightly larger diameter than the dot at that distance and center the dot inside that ring when aiming. Shoot 3-5 shots and adjust the scope accordingly from the center of that group. Don’t spend any more time at shorter ranges than it takes to get the windage perfect and the elevation close enough to get on paper at 50. Last but not least… Try not to do it on a day when there are 20 guys on the line shooing big/loud guns!
Just got in from sighting my aimpoint pro. Kind of surprised that I have to move the elevation so much, but windage was only three clicks off. After getting the elevation right, I was tickled to death with my five shot groups. All were OK, but the last one could have been covered by a silver dollar at 50 yards. I was using PMC .55 grain Xtac in .556. My rest was on a eight foot table, and rested the rifle on a seat cushion. Very easy to hold steady, and very comfortable as well. Needless to say, I am well pleased with my colt le6920, and the Aimpoint PRO.

Appreciate the replies. I have the rifle zeroed fine, but I was surprised that the elevation was off about 18inches. My understanding was very little adjustment would be needed, since they say only minor adjustments will be needed. But if my memory is correct, I moved the elevation screw about 22 clicks. No matter, the rifle is dead on at 50 yards. (I could be wrong about the number of clicks.) It took me I believe 31 rounds to get it zeroed.
Maybe you pulled the shot that low. 22 clicks at 50 would only move the POI 5.5". It doesn’t matter. You got it sighted in. That’s all that counts.
I do the 25y and then 50y method. My AimPoint Pro was damn near zeroed when I put it on. All of my AimPoints have been extremely close.
I first center up the irons so that they will be on paper, and zero them. Then install the Aimpoint, and adjust it so that the dot is sitting on top of the front sight post. This will ensuure that it will be very close to a zero, and only a bit of fine tuning will be needed. Remember that it has 1/2 MOA clicks. I think I got the last one I did zeroed with two 5 round groups this way… plus maybe 3 groups to get the irons on.
Thanks for info. Everything is A-OK now.
Maybe I’m lucky, I’ve sighted in exactly 4 red dot optics and the most rounds I expended doing so was with a Primary Arms H/T-1 clone on a dedicated .22LR upper (took me approximately 14 rounds). My T2 only took 6 rounds.
My procedure:
Use two different cartridge-style laser boresighters to get on paper.
Set up a target at 25 yards and a bench and table with a shooting bag.
Pretend like I’m the greatest sniper who ever lived and aim for the exact center of the target.
Walk to target to see where I actually hit then adjust the windage/elevation turrets according to feeling.
Repeat until zeroed.
It’s always worked for me… I realize that it’s not the most scientific method, but it’s cheap, quick, and seems to work just fine.
