This video offers a side by side comparison of the various AR combat zeroes. We take a look at actual down range performance of the 25/300 yd zero, the 36yd, the 50/200yd zero and of course the 100yd zero at various distances. We shoot each zero at the 25, 50, 100, 200 & 300 yard lines and then at the end of the video provided a detailed look at the point of impact vs point of aim for each zero for the various distances. Here we utilize real world results vs theory to dissect the performance of each zero to help you determine which might be best for your application. Rifle is a colt 6920 updated to be a sopmod block II clone with 14.5″ socom weight barrel. Optic is a vortex razor hd gen 3 1-10 optic with mil reticle and suppressor is an old school surefire FA556-212 pre socom can.

23:01 Final thoughts and closing
I use a 200 as of now.
Got a Vid for that one?
Great work, very helpful.
Thanks. Best video on zero. 💯
New subscriber thanks to this video!
Excellent and thorough video! Thanks brother
Remember your holds, practice estimating distance, and you will be fine. Just use whatever holds are easy for you to remember
Very good video, thanks for the information!
Very nice
Ultimately, it depends on optics snd general purpose. A rifle that is used primarily for CQB is a 36/300 zero. Sharpshooters and snipers, 100 yards.
so i did remember right. 25 yard zero more or less levels out at 300
Great video on the topic.
I like 36 for anything 1x. I have a leupold that requires a 200 for the ballistic reticle so ~50 (of course that's 5.56) I also have acss scopes that have their own requirements. Recently I've be interested in trying a leupold freedom 2-7 and doing a 36 yard zero with it. I wish they'd put the tri-moa and CDS on/in that scope.
But honestly, at this point, chrono the gun and calculate mpbr on 6" (or whatever you want), zero at the close end then verify at the long end. Adjust as necessary and label the tool. Even more so when you have a modern MOA/MIL reticle so you can get a good mental starting point when doing holdovers.
Quality video
I don't know you from A to Z but mam you've got a new subscriber because you really put in the work on this video man…keep up the good work
absolutely fantastic video. Extremely comprehensive my friend. I've been running a 50/200 yard zero for quite some time, but you've got me thinking about switching to a 36 yard zero myself. Keep up the good work my friend. God Bless.
All I know forsure is a 1:12 20" barrel with 55gr ball is 25 m and 250 m. Below 250 aim low. 250 upto 500m you aim at the head
This video doesn't make sense unless you are using the a2 sight. The 25meter zero was only intended to be used at 300m+. You need to flip to the the large aperture, which gives 50meter zero when the small aperture is zeroed for 25. The marines only used the small aperture and had a 36 yard zero but dialed down for less than 200. The 25,36 zero only make sense with the a2 sight system.
All Jarheads set their BZO at 36 yards and confirm at 300. Never, ever failed me in battle.
Great video, I run 100 since I shoot a 6.5 cred and I use EBR-2 tree on my scope. But will explore 36 on my Ar.
Thanks
I really appreciate this video. It was great. Do you think the suppressor makes any difference on point of impact/point of aim?
Great work
I wonder – is the 36yd capturing the peak of the arc? This could be deceiving. Like maybe at 225yds it’s going to 5.5” like the 25yd zero was at 200 yards. It’s just shifting the peak of the arc to a yardage that’s not being captured by this particular test
Excellent work man. Super detailed and a fantastic presentation. I learned a lot, thank you. Subbed 👍🏽
Get a 600 yard range, put a green laser where the gun will sit and center it at the 600 yard target that is about 6 feet tall with the bullseye 3/4 up from the bottom.
Then moving towards the gun, place aother target keeping the laser dot centered.
Fire 1 shot and you will see the complete trajectory of your round.
Paste the holes, choose your maximum zero from there.
With my 45 Raptor I have a 6 inch target I can hit out to 300 yards holding center mass.
MPBR
No one has ever explained it so simple and succinctly . Cheers!
I rather have 100 yard zero with a 45 degree red dot set at 25 issue solved
Excellent video. Thank you.
36 yd is best for any dot sight. Any BDC system, zero at manufacturer specified distance. Easy
well produced video, great for visualizing the drastic changes zero distances have. however, everybody should download to their phone and become familiar with one of the ballistics software programs they have out their. they are all pretty good, and all will allow you to see the changes that will be made to your impact points based on barrel length/bullet weight/optic height.
outstanding sir. new subscriber
How much does ammo offset this?
I zero at 100 because my LPVO works off of it. I’m usually shooting groups at the range. My battle rifles are usually iron sights and I zero at 25
Does it all depend on calibers , for example a 6.5cm ?
Very interesting! Right now I'm at the 25yrd but I plan on trying the 36yrd to see how I do with that. Thanks!
36 yard zero is by far the best way to go
Superb video. I’ve watched others but this was very comprehensive.
With a 50 yard zero I'm basically on out to 200 yards with only a little holdover required foe easy 300 yard hits. It kind of works for me for 5.56. Nice optic.
I thought I would skim through this video but I watched it all the way through. It was very interesting and explanatory. Thank you.
The zeroing rifle at 36 yds is also good to set up an holographic Eotech ??
One of the best vids for zero 🇺🇸 thx
I can't trust anything you say.
You're not wearing body armor.
You're not rocking a oak ridge boys style beard.
You're not dropping F bombs every third word.
And finally, You're not using a 8 grand rig with every attachment know to mankind.
Nope, not trust worthy.
Keep up the work, new sub here.
Great video, chum.
I wish I found it sooner.
That simple diagram explains so much without words!!!
SUGGESTION: plot these out on an x/y and use a polynomial generator from the points to graph out the arc of elevation v distance of each zero superimposed together. I think it would go a long way to illustrate the difference in rate of rise/fall from each zero at each range.
Also, you mentioned the value of being more zeroed at ranges/distances where it’s hard to judge distance/holdovers. That would really drive that home as well.
Awesome job.
Oh, and considering the low elevation error you corrected after shooting the 50yd zero from 50yds… two things:
1) the plots mentioned above would have to be re-done without the error.
2) didn’t you have that error when shooting the 36yd zero? Are you so sure it’s such a good option then?
Maybe re-do this and be super-sure of your zeros – maybe start at the zero distance – before shooting the others. 🤷🏼♂️
Just, don’t do it with a sharpie on cardboard 😂.
36 yard zero for no magnification (red dot)
100 yard zero for lpvo 1-4,1-6,1-8,1-10.
I would like to see a comparison with the other popular rounds (300, 308, 6.8 etc)
