This is a stripped down basic tutorial for the AR15 Battle Sight Zero procedure.
Utilizing a standard M16 or M4 BZO target, an AR15A2 rifle with irons sights, and a known distance of 36 yards, we will learn how to properly apply a 300 yard BZO to our rifles.
You must first establish mechanical zero on your rifle prior to firing.
Spin your rear sight windage knob all the way right.
Count the amount of clicks it takes to spin the windage knob all the way to the left side of the rear sight housing.
Take that number and divide by 2 and apply that number of clicks right on your rear sight windage knob.
Set your rear sight elevation knob to 8/3 or 6/3 respectively. Your rear sight is now set for mechanical zero.
Using a 5.56mm round or a specialized front sight adjustment tool, adjust your front sight so that the base of the front sight post is flush with the front sight assembly. This is mechanical zero for your front sight post.
Once at the range place your BZO target exactly 36 yards from the muzzle of your rifle. Since we are simulating a 300 yard range this placement must be accurate.
We are now ready to begin firing our grouping shots.
With a magazine of three rounds, load and make ready. Once you’ve established a correct sight alignment and sight picture, slowly squeeze off your first three rounds. Take your time and make each shot count. A day pack or some sandbags will help stabilize your rifle for quality shots. We are adjusting the sights to the rifle. Stability is key to getting good results.
If your initial group is far off of center mass on the BZO silhouette, count the number of clicks on the BZO target and apply this to your sights.
All elevation adjustments will be made from the front sight post. All windage adjustments will be made from the rear sight windage knob.
Once you are shooting consistent groups center mass on your BZO target your rifle is zeroed for 300 yards.
(Back at home) Spin your rear sight windage knob right and count the number of clicks until it stops. Applying that number of clicks, spin your windage knob left. This is your rear sight BZO. For example, my rear sight BZO is 45 left.
Rotate your front sight post and count the number of clicks until it is flush with the front sight assembly. Re-apply that number back to it’s adjusted position. This is your front sight BZO. For example, my front sight BZO is clockwise 5 or “5 up”.
Record your BZO and store it in your butt stock or some other place where you can easily access it in the event your sights become spun out of adjustment.

QUESTION ? : if you sight your A2 rifle in at 100 meters at the 3/8 position, where will the rounds print at 200 meters if you use the 4/8 position ?
2019 …. a recently retired 21 yr. Navy combat warier veteran and I were at the range i,m firing his wepond, and he,s laughing at me……. I,m launching rounds over the targets head. HE shouted, shoot at the feet… SHOOT AT THE FEET……. W.T.F. what an aphiny … you will never ever miss a RUNNING target again….. Rob is fresh off the battlefield. this is 2018 doping for iron sights… >.Aiming his M4 at the feet , his impact is actually j hitting just above the waist,,……….as the M4 rises while firing multiple rounds, you impact the whole upper torso with multiple rounds. on the muzzle rise……….. .. The runners forehead , is the angle and lead of that targed… ….DRAW an iminagery line down to the ground Thats your lead , SHOOT at the feet, youll impact the whole torso with multiple rounds, as the M4 rises……THATS DOPE. God bless Rob. god bless our Veterans, God bless America
Is that an A1 Front Sight Post on youe A2 ?
What's the best zero range for a AR15A4 (20" bbl., carry handle and FSP)? I shoot 55gr. 5.56 ammo.
A1 round front sight post with A2 rear?
That is the best way to Get a 300 yard Zero, now your good for Point of aim point of impact at 300 and at 400 yards you will be low at the stomach area, without a hold over..
so at this distance, if my POI is 2 inches left, would I make 2 clicks right? like at what distance does 1 click = 1 inch?
when do you adjust the rear sight elevation?
Great video, sir! Thank you!
Shouldn't you set up a 25m target at 25m instead of 36yards?
Man that wind.
why not bzo for 200 yards. at 100 yards you will 1.6" high and dead on at 200. also mark your bzo with paint so you can go back to them when needed.
for the targets that are avail — they are all for "25m bzo" it seems, are the clicks "close enough" to be used correctly for a 36y target? i like the 36y zeros theory, and it seems easy enough, but the targets don't seem to jive with the zero? I guess at the end of the day, if you are hitting POA at 36y then you have the zero, just figured that someone would have "scaled" the 25m target to the 36y target by now?
I've found a couple marine corps pics that show them using a "36 YD GROUPING/BZO TARGET" but I can't seem to find a copy of it?
Your post and video mention 36 yards, (which I've heard before is best) but the targets are stated for 25 meters. How do I adjust for this?
why you didn't explain how may adjusting use elevation?
Can you help me understand why you are setting the 25 meter zeroing target at 36 yards? I looked through FM 3-22.9 "RIFLE MARKSMANSHIP M16-/M4-SERIES WEAPONS" and I couldn't find any use of that target at 36 yards, only at 25 meters. As I understand it, that is the resource distributed to the Army, Army National Guard, and U.S. Army Reserve for training on the M16.
PLEASE understand that I am NOT trying to be a smart azz….I'm just trying to learn and understand. Any info that you can share would be helpful. Thanks!
Brother, I have commented on your video and yet to give you credit. Great video Devil.
Excellent video, sir. You wouldn't happen to be a former Devil Dog now, would ya?
Very well done video. I used to tell my guys that zeroing is not a timed event. The accuracy only comes from doing your best group. The Army allocates 19 rounds to get zeroed – people that went slow usually took 8-9. People that went fast took all day.
If anyone here is shooting a Trijicon ACOG RCO on their rifle and needs a good tutorial for zeroing, check out this video on goldspurs09 channel:

Excellent, thank you.
When zeroing your rifle, I recommend a non-windy day (video show wind). One you have zero'd your rifle, windage adjustments can be calculated with accuracy. If your planning on shooting 50 meters to 300 meters, zero at 50 meters because of the AR15 projector has a rise and fall. This 50 zero allows for hiting 50,150, to 300 meter targets without adjustments. Youtube can show you the rise and fall range differences. Military 25 meters works to but you have to aim slightly lower at close targets and higher medium range targets like a rainbow.
Okay, some stupid questions from a relative newbie to the AR platform. Are you using the M4 Carbine 25 Meter Zeroing Target at 36 yards for the 300 yard zero? If yes, why does this work if 25 meters equals roughly 27 yards, not 36 yards? Would I not need a zeroing target properly scaled for 36 yards? What target does the Marine Corps use for its 36/300 yard zero? Any help that you can provide will be appreciated because I am totally confused.
Why does the target say 25 meters and your instruction is to set the target at 36 yards? 25 meters is 27.3403 yards or 82' .25" Am I missing something here?
Martian59 I don't believe anyone has answered your question so here goes.
The 6/3, 8/3 simply put is the setting for the elevation of the rear sight to place rounds on target at 300 when bottomed out or 600 when fully raised, and same with 8/3, 300 bottom 800 top. I hope that helps. Also, the large rear sight labeled 0-2 is for 0 to 200 yards, meters and is also called you combat sight/night sight due to the larger field of view and more light being channeled to your eye. The peep or small aperture is for precise shooting from ranges of 300 to 600/800. So there's really no need to change the aperture once your zeroed.
Just a reminder for anyone looking to use this tutorial for your rifle sights, be sure to save the link for the targets up in the description section. Save the PDF to you computer so you can have access to the BZO targets any time you need to print them out. Have fun.
Did you have to prime or sand it first?
what kind of paint do you have on your weapon?
Thank you for doing this video!
I have performed this BZO since the early 80's. I have never seen the procedure after numerous courses and endless range time put so simply and eloquently! Excellent video with brief but informative narration and fantastic visual aids. Good job! The Army needs to adopt this video or hire you for their Training Manuals and Films lol. Thanks again.
Thank you for the simple instruction. I'm writing a book and I needed to use a mechanical and battle sight zero analogy. It's been years since I've actually done it on the range.
I got a Windham Weaponry AR, the 'MPC' model. Looks just like the M16 with the iron sights & carrying handle. Old US Army 19 Delta/ CAV SCOUT trying to remember all these steps so Im GLAD I found your video. Old Sarge has been out since 1984 so the brains cells have dimmed abit:) Cant wait to shoot this weapon today in the desert:)Waited for one of these since 1974 FT Polk Basic Recruit Training OH YEA!! Take care 🙂 Herb in El Paso Tx "This SCOUTS OUT!"
Brings back memories to my infantry days. Good job. –Stand And Fight For The Second Amendment–
I just received a Daniel Defense A1.5 Fixed Rear sight. Could I still achieve this zero?
Thank you for the instruction, I want to leave my AR as "naked" as possible. I am not putting any optics on top and want to utilize the carry handle and front sight only. I have 2 questions please. 1. Going back to gibvel's 6/3 question, I understand about the the 300 zero but does this mean that the 6 of the 6/3 would be for 600 zero by flipping the second sight ring into place? 2. What is the general trajectory difference between the Federal XM193 and XM855? Thank you.
Glad you enjoyed it.
The 25 Meter BZO target is the NATO standard for a 25 meter / 300 meter BZO. I am showing the process for the 36 yard / 300 yard BZO. You can actually use any target of your choosing, but for purposes of this video I am using the 25 meter BZO target. It won't affect the zeroing of your rifle.
cool! Thanks for clearing that up!
Some rifles have an 8/3 rear sight elevation knob and others a 6/3. It's dependent upon the rifle. Generally the 20" models will have an 8/3 knob and the carbine variants will have a 6/3. The idea is that the 20" rifles are capable of shooting up to 800 yards accurately and the carbine rifles up to 600 yards respectively. For the purpose of setting a BZO, this difference in sights does not effect the 300 yard zeroing procedure.
What does the 8/3 and 6/3 mean? My M&P 15-22 has the 6/3. Does the difference between 8/3 and 6/3 have any bearing on how you set the zero or what target or distance you use to zero the rifle?
