AR15 Zero: Introduction to Sighting in a Rifle's Point of Aim on a target at a Specific Distance 

I am retired LEO and an AR 15/ M 16 Rifle Instructor trained by THE NRA and The NJ Police Training Commission. I only say this so you will understand my feelings on you presentation. "OUTSTANDING". Hand outs and chalk boards can not touch this. The graphics and the simple break down in common language earns an A plus in my book.

This was amazing. Very concise and simple way to relay a relatively complex concept. Thank you

Explained very well. Thank you for this video.

Brilliant explaination as I have heard, do wish you spent more time on each target and chart after intial 25 yard one though, where this helps me is due to may lack of ling range shooing ranges, with 50 being all I have.

Fact: to enjoy the AR’s bullet drop compensation function you must zero for 300 meters, which can be done by sighting in at 25 meters since line of sight and point of aim will intersect twice, first at 25 meters and then again at 300 meters.

Great job!

the best method is first identify the size of the kill zone, then the max distance you want to hit the kill zone, then pick the flattest trajectory that hits the most kill zone targets out to your chosen distance, i myself perfer a no hold over trajectory for the simple reason that front sight can block view of where you need to hold, especially at long ranges but what really matters is what ever zero you choose its if you hit your kill zone wether you hold under or over knowing where to hold to hit your kill zone, shooting air rifles also for most of my life having a dozen different velocities, over 100 different pellets with different ogives and profiles and over 25 different grain weights, we air gunners know trajectory well because we have to, we have much more drop, lots of wind drift, we make more ballistic calculations for targets of many sizes, and other variables to deal with far more then center fire rifles wich gives us vast experience because we shoot alot being the cost is cheaper to do more tests, at the end of the day its all about hitting your kill zone out to your prefered distance despite your zero, if kill zone target gets hit every time with using more then one sight in then it doesnt matter, its all about making hits on kill zone never missing any out to your disired distance you choose, combat, plinking, competition and even extreme long range are all different from each other. in a imperfect world you can have flat shooting with out hold over nor long range shooting with out hold under, some where in a trajectory path you will have hold under and hold over depending on distance

Outstanding video!!

So this makes me question my sights. If I’m using something like a m bus pro that’s adjustable on a 16” 1:7 what do I use as a zero that would most accurately represent the adjustments on my sights? It seems like using these different zeros would have a big impact on those adjustments.

Which type sight are you talking about, you got several, I know the video is old and needs to be updated. But it would be good to know!

Thanks for the pdf

Best video on Zeroing the AR15 ever made!!! Takes all the mystery out of it in just over 5 minutes.

Damn, I can't decide between zeroing in at 50 yards or 100 yards. 100 yards seems to have the most pinpoint accuracy at 200 yards and below, while a 50 yard zero gets you close on target up to 300 yards. I believe I'll go with 50 yards, as it's better to have it and not need it, than need it and not have it. Because I don't think I'll ever be shooting 300 yards for fun, and with a 100 yard zero, target shooting at 200 yards and less would be easier to point and aim... but I can learn with 50 yards and then have an easier time at 300+ if the need arose. Thanks so much for this video. Quite possibly the best video I've ever seen on RU-vid, PERIOD.

This is _extremely_ helpful. I was contemplating a 25-meter "battle sight zero," but since my local range only has 50-, 100-, and 200-yard targets it looks like a 50-yard zero would be just about perfect. Here in Florida we never shoot past 200 yards anyway.

once again, whether you said so or not, this information proves the 50 yard zero is superior.

20 yr. LEO here, and a firearms instructor with my department, to include former SWAT team member & state certified Sniper. I'm teaching a class at my department for basic patrol rifle skills and I was building a power point to show the new officers how to sight in their rifles and explaining the ballistics of the round. This is the best video I've seen yet, and with your permission I'd love to include it in my presentation!!

Thank you. I had previously zero at 250 yards to get the tight groups out to 250. Without a 250 yard range I've been shooting at 100 and looking for the hit to be about 2 inches high. I didn't even think about zeroing on the rising side of the trajectory. I can zero at 50 and get the same results without the guess work. Awesome video.

Very nice job on video. I'm prior Army and have my fair share of time behind the trigger and thinking back to basic training many many moons ago, I wish we had this way of teaching available at the time. Keeping things simple and easy to comprehend is proven to be the best way of teaching and the easiest way to learn and maintain what's being taught. Some think it's better to use big words and complicate things to make the class seem more professional. Great job guys.

This is a great video on the topic, probably the best video of its kind on Ar15 zeroing. Great job Gwebs, an oldie but goodie.

TY for this. Exactly what I was looking for. I am not a novice to shooting but I have really only started really educating myself in debth about shooting in the last few years. I am setting this to favorites and sharing it to people I know who might get some use out of it. Thanks again.

best zero tutorial on youtube.. thank you I've been struggling with getting my zero right for a long time.. now I really know why that was.

Wow, this is a great way of explaining everything. Thank you for putting this whole program together and not just showing a piece of paper on top of a table and just using your hands, which is what I see a lot of.

Thanks so much for this video. Today I took my M4 profile AR to the range, and shot at 50, 100, 200, and 300 yds. I had previously zeroed it at 25 yards. Your trajectory graphs were in my mind as I shot, and helped me to understand what was happening. The 55 grain .556 at 300 yards was back to zero, more or less. Again, thank you.

Well done... Clear, concise and educational. I can't imagine why the dislike button was even touched.

You answered all of my questions in one good put together video. Thanks!

man didnt even find it this easy to learn in school,i round this really easy to understandand pay attention to and thats saying something,nice work

This is really fantastic work sir. This is so much easier to explain to friends and family now that i have this video. You won the internet for today.

Very nice explanation. The graph from different angles really made the points crystal clear.

Good quick explanation and use of charts/graphs. I liked that quick presentation. Thank you. Good job.

The quality of your illustrations is simply OUTSTANDING! Thank you.

Awesome representation of the zeroing, trajectory/path etc. Wished I had seen that at the onset of shooting for me way back.

I still show this video to friends to teach them some understanding of ballistics and zero concepts. Well put together.

Outstanding presentation and explanation. Answered every question i had.

Man that is a great illustration. I have read and researched pretty good online on zeroing ar's with red dots and irons. Having no military training it was a difficult path on understanding zeroing especially AR iron sight adjustments. This illustration is better than what i have read on alot of AR type forums. Thanks and keep it up.

This is one of the best videos on the net. Great presentation and great way of conveying it. Great teacher!

This is by FAR the best video /information I have listenedto,seen or read explaining how/why you should sight in at a given distance. Look forward to checking out your other videos.

I just completed my first build and ready to take it to the range. It'll be primarily a coyote rifle, And this really cleared things up. Most of my shots are sub 100 yards but I'd like to be able to poke out to 200 even if need be. I was planning on a 25yrd 0 but a 50 yard zero seems to fit the bill for my situation. Great video

this is a very useful way of getting the information out there. the dots on the targets at different distances makes it easy to understand

Excellent video. Good for rookies and veterans alike. Thank you.

Great informative and very educational. 50 meter is the magic spot! Thank you for time and effort in putting this together

I finally get it! Thank you. In the past I have always adjusted my sights where the impact point is higher at 100 yards than 25, I see it don't work that way so I was always working against myself and shooting high. Great video.

I add to the thanks, just purchased my first AR and this video was extremely helpful. I'm mostly a pistol shooter, so I didn't have much of an idea how to sight in my rifle. Thanks again!

Best visual presentation of this I've ever seen. This should become the standard way to show this IMHO.

I've seen almost all your vids and I have to say this is your best and most informative vid of all. Great work.

You are very clear and concise. For some reason your voice resonates well in lecture. Great job.

Outstanding. I never realized the rise was so great. Setting up my sights just got a lot easier. Thank you so much.

Thank you for an excellent video. Your video really explained it well. Great job!

Probably the best Zero Video I have ever seen . Great skills on the computor as well .

Your presentation in this video is the most awesomest! You lecture outline combined with graphics make this topic easy to understand. Thank you.

@trollprepper yup, we did all this from scratch, there wasn't anything we could find to explain it this way thanks for the kind words

Great explanation! Thanks for making this.

That was the best explaination and layout of that explaination that I have ever seen.

what a great visual breakdown on those graphs, thank you for the time it took to do this video, much appreciated

Outstanding presentation. Thank you.

GREAT video. Very informative and clearly explained. Thank you for taking the time to make and post.

by far the best explanation on youtube

Loved it. I just got some great info thanks.

You guys do the best videos. Thanks please keep it up.

Super informative video... you guys are awesome - thanks!

This is a fantastic perspective on Zeroing and trajectory...great graphics and explanation. Looking forward to seeing your more detailed work. Great job!!

thanks, every time someone has instructed me on this stuff I wished I had something like this.. so it was a learning experience all around

Excellent info. Very well done. Thank you

Thanks for the great video. Very good for a beginner . Thanks 👍

Fantastic Video! Heading to your website immediately. Looking forward to the future vids on this. Graphics were amazing.

Great video and THANK YOU for the PDF. This should be required reading for every civilian AR15 owner.

I have always used 200 yards. however i know what exact turns/clicks I need to make it a different zero depending on the situation. I must say this is the best video explaining zeroing. i used it to teach my son some info cause i've never been able to explain it so well.

Excellent graphics & description.

Great video, Best explanation I've ever seen. Good stuff.

Well done, brother. Well done. Was cool seeing you that day setting up the shoot, too.

Excellent video, easy to understand. Obviously put a lot of work into it, thanks for posting.

So many people I used to shoot with just couldn't grasp the notion that the AR15 is better zeroed at 50 vs 100. But having 55 grain rounds and 65 grain rounds some in the same mag. Using a 66 yd zero puts me in a sweet spot with a human size target up to 300 meters without ajustments. If I want to get more serious I check my notes for the drop over distance with the grain of bullet nneing factored. It's a good habit to get into for serious shootings. To memorize your bullet travel rise and fall with muzzle velocity. Plus it impresses when you can say specifically how much the round will fall over the next 50 yards.

WOW! That was awesome! very easy to understand!

thanks for this video just got my first ar15 the other day starting 3gun in a few months this helped me alot once agin thank you and keep up the great work mate

Excellent video!

Thank you so very much. We need the basics and your an excellent teacher.

Clear and informative. Thank you.

Excellent vid zeroing made easy! Thank you

Thank you so much with the informative video. I'm new to the AR-15 scene and this make clear how the "zero" works. Nice graphs! Thanks

Very well done, a lot of work went into this!

Wow, excellent presentation.

Great video. Great graphics and very understandable. Nice job.

Excellent video. I learned a lot.

Very good and informative video!

Great video, was very easy to follow even though I was sceptic at first.

Priceless video. Thanks loads.

Excellent work, thanks!!!

Very clear and well done. Thanks

In these examples, the sights are at the 0 point on the graph, the AR15 barrel is sometimes 3" below the sights / optics, so in these examples the bullet starts at a 3" drop from 0 The AR is like other rifles and the sights end up pointing down a bit, so when the sights are brought up to the target, the barrel is, in effect, pointing up a bit

Great video, I’m brand new to guns and followed along fine. Thank you

Excellent instruction!

Love the vids. Awesome editing skills.

Great Video! super helpful!

excellent presentation

That was amazing! I never understood it really, till now.

Thanks for the great explanation

Excellent, I look forward to follow up vids and discussion.

Well done! The first vid to visually explain the trajectory of a bullet. I'm looking good with a 50yd zero, thanks!

thanks, that reassures my decision to zero my 223/5.56 guns with irons and red dots for 50 yards. My standard AR is an A3 with a holographic red dot and 45° iron sights both are set at 50 yards. My longer range AR is also an A3 but it's a spike's tactical with a nikon p-223 3-9x40 BDC 600 which is zeroed at 100 yards and works great with the nikon spot on app. it also has 45° irons that are zeroed for 50 yards. the free nikon spot on app is great even if you don't have a nikon scope. Just find one from the large list that is similar to your's. great video, thanks for reassuring my set up that I've been using for 7 years. I assumed it was the most efficient from all of my testing. seeing it proven on video with an animation just helps that much more.

Excellent Video

Great info!
