AR15 - 25 Meter Battlesight Zero

[@coloradocraig]

Thank you. My new AR is a lot of fun and I'm learning new techniques. Your explanation was the first that was clear and made sense. Not boring at all.

[@dtelaw]

I have recently renewed interest in my iron sights over optics. This is one of the best battle site zero videos I’ve watched. Very helpful.

[@johnlaursen6080]

I just bore sighted my Springfield Armory Saint today, it took me 9 rounds, three rounds at a time. This is pretty much the same as I did it in the Army. In the Army they gave each soldier three five round magazines each containing three rounds. This I believe was a smart idea as this insured that when the shooting ceased after each three round shot group the bolt would retract and verify that the weapon was cleared. You have to remember that for a lot of these individuals this was the very first time they ever held a weapon let alone fired one. Better to be safe than sorry.

[@geraldwest3428]

Excellent tutorial, straight to the point without all the additives and preservatives. Thanks for your time and talent, Miller!

[@gilbertdiaz6838]

Gerald West bullshit this video drags way to long with nonsense bull talk. Lose interest real quick.

[@ecoovert]

Your video wasn't boring to me. I already know how to sight in a rifle, and already have my ARs sighted in. I chose a 50 yard sight in for a flatter trajectory but I still enjoyed watching your video. You applied the same principles that I use except for the 25 yard sight in distance. I understand that sight in distance is just a matter of opinion. I see you posted this video a few years ago but I understand that these days, at least some of our armed forces are moving towards a 50 yard sight in distance. Having been a type one diabetic from the age of two, I was never able to serve so I have to base that last statement off of research I have done. I have considered both sight in distances and at least for my purposes, sighting in at 50 yards makes more sense. Lest I forget, I would like to thank you for your service.

[@huh4233]

Beautiful! Reminds me of my time in 25th ID. People make zeroing an AR much harder than it needs to be. Do it like this and you're ready to go. Too much hollywood/playstation BS these days. Thank you for a real good tutorial.

[@aaron-siyambo4139]

But how exactly do I rotate the screws and knows? My AR12 has only lines on the rear sight and nothing on the front sight. But how far do I rotate?

[@MuzzleDoc086]

Patient, thoughtful wording, great instruction , most helpful,, Thank You

[@daverotroff6873]

Great video. Identical to what the Army taught me in the spring of 1973 Ft. Jackson, SC. We were shooting the A1 version. Both the front sight and the rear sight adjusted with a bullet tip or sight tool which no one ever had. Of course the carry handle was part of the upper assembly back then. No rails and no drum adjustment on the rear sight. We were taught the 3 shot zero method at 25 meters on a target that was called a Canadian half bull as I recall. A tight 25 meter zero gave you accurate hits at 300 meters. Any target in between 25 meters and 300 meters required holding low on the target. How much low varied with the actual distance to the target. Many people don't understand that the bullet crosses the line of sight twice. With the 5.56 ball ammo and a 20 inch barrel it rises across the line of sight at 25 meters and drops back down across the line of sight at 300 meters. One zero for 2 distances.

Although the novice watching this video will be able to get a BSZ and a BDC function, he will still have no comprehension of how many clicks of windage would be needed to counter for wind when the correct favor for wind can not be discerned from the sight picture. In other words "let's see what 4 clicks will do", does not cut it, it does not have to because we already know the M4 windage knob has a 3/4 minute of angle value and the front sight has a 1 3/4 minute of angle value; thus, using a little math we can easily discern exactly the amount of movement a sight adjustment will make in inches at target distance. Here's how to do it: 1. First, think what the value of 1 MOA is at target distance: Distance to Target in Meters / 100 = Value of 1 MOA in Inches at Target Distance 2. Next, think how many of those MOAS will fit into inches of needed movement: Inches of Movement Needed / Value of 1 MOA in Inches at Target Distance = MOA Adjustment 3. Finally, determine how many clicks to sight for needed movement: MOA Adjustment / Sight MOA Click Value = Clicks to Sight for Needed Movement For example, let’s say you’ve set your target out to 25 meters and you’ve produced a group which is 2 inches low and 2 inches right of the target’s center. Remembering the front sight has a 1 .75 MOA click value, and the rear sight windage drum has a .75 MOA click value you can now determine sight adjustment needed: First, determine adjustment needed to front sight controlling up/down movement: 1. 25 Meters / 100 = .25 Inches 2. 2 Inches / .25 = 8 MOA 3. 8 / 1.75 = 4.75 clicks (round to 5 clicks) to front sight post in clock-wise direction for needed vertical movement of grouping on target Now, repeat steps to determine adjustment needed to rear sight drum controlling left/right movement: 1. 25 Meters / 100 = .25 Inches 2. 2 Inches / .25 = 8 MOA 3. 8 MOA / .75 =10.6 clicks (round to 11 clicks) to sight windage knob in left direction for needed horizontal movement of grouping on target Creds: CMP-USAMU certified MRI coaching SDM/SAFS, US Distinguished Rifleman, and NRA Long Range High Master Club

Thanks for a well done video. I agree with other viewers it is never boring to watch someone doing something the right way. I know this was not a marksmanship training video but I would emphasize how important it is to get a good cheek to stock weld as you did and try to repeat the same every time.you shoot. It was neat to observe your calm concentration when putting those rounds downrange. And for newcomers it would never hurt to remember the acronym we learned in US ARMY BCT " BRASS " B reathe R elease half A im S queeze S hoot I built my own AR-15 from a stripped lower and I loved going shooting at the range. For me it was my own form of meditation. Attempting that perfect shot group. Unfortunately due to some personal challenges I had to sell all my guns to help raise the money to move from Houston, Tx to NC.

[@alancranford3398]

Three rounds vs five rounds--in 2009 the Army marksmanship training unit brought this up at Camp Navajo in marksmanship classes for the 442nd Signal Battalion. Three shots is enough if you are proficient. You might want to fire one shot and adjust when ammo is short. Three shots prevents mistaking a flyer for your group center. You get an average group center from three shots as long as your group is tight--no more than 1.5 inches. Your three-shot group was under an inch and is fine. Five shots for poor marksmen works like this--fire five shots and take the three bullet holes that are closest together as your group--discard the other two as flyers. As long as three of your five shots group within 1.5 inches at 27 yards (25 meters) that will work for determining group center--60% of your bullet holes are landing in the same area. From 1975 to 2010 I qualified with the M16 service rifle an average of three times every two years. I trained something like 2000 other people in M16 rifle marksmanship during that period. I am also an experienced military armorer (additional duty).

[@charlesludwig9173]

Remember your coach asking you “how did that shot look”. For a shooter who can call his shots three rounds is enough to get a good zero, but for ALL shooters, including High Masters, triangulation of 5 shots which exclude up to two which seem to be out of grouping might yield a better no-wind zero. It’s why the USAMU says do 5 shot groupings when time and ammo allocation allow.

[@antoniocomputersbarreto7429]

Awesome 👍. I just got my new Windham Weaponry AR15. I'm going to the range on the 31st and I will remember your advice. Thank you so much. God bless America long live the Republic

[@hoserseventwo]

Simple and straight to the point. Not a boring video but educational for AR owners. Thanks.

[@thehoneybadger8089]

Nice square-body Chevy/GMC. I'm still driving the Heavy¾Ton4x4 I drove new off the lot in 1984. It refuses to die!

[@benjaminarmstrong7047]

Just went though this today with my first AR style rifle. I am pleased with the results!

[@uilleann86]

Boring doesn't matter. A weapon that isn't zeroed is an ineffective weapon. A lot of new shooters I see are impatient, and could learn from videos like this. I actually enjoy sighting in my firearms, I love the challenge in the precision of it. It calms me. Well done.

[@janwilliams178]

Thank you very much, I'll be heading back to the range Monday and can't wait to use this technique.

[@williamlaubenstein4130]

Very good information on how to sight in an Ar15 ,I will try your way step by step as I just bought my first AR, Thank you !

[@JW52654]

Very clear and to the point information without all the Phucking bs, like other videos with guys who like to hear themselves talk. Thank you very much my brother in arms.

[@pmsegal7103]

I liked the video, you got right to the point not alot of rhetoric BS. Well done, thanks...

[@joeprepper8172]

Thanks for your input, seems like everybody else made it sooooo much more complicated than it should have been.

[@armeddefender]

I keep it at 300 because I can flip the aperture for closer ranges (I can still hit pretty good with the large aperture out to 200 meters). Flipping the aperture would be just as quick as adjusting clicks. An easier method for me is to just hold slightly 6 o clock for closer targets. Range estimation is pretty easy and fast with standard irons. It's just what works for me.

[@jonathanwhitson802]

No I wasn't bored with it it has been a big help. On my new ruger 556 thank you

[@jessethebaldyventura2391]

Nice and informative. My only piece of advice would be not to zero with the wind blowing. If the wind is strong enough to drone out your phone, it may have a slight effect on your point of impact.

[@kevinleandro6367]

I would add: dont break your stock weld and stop hooking your finger around the trigger. Use the pad of your finger to acheive a stright pull.

[@tires2burn]

I don't think your video was boring. I learned a lot. Thanks

The one thing I really like about the M16A2 is how easy it is to zero. They really designed it with that in mind.

[@garyfreeland5154]

Its been a long time since I've fired an AR15 but I'm really going to use your firing methods to sight in my AR15.. Also if I have any problems I'll rewatch your youtube post.. Its been 48 years since I've fired a M16/AR15.. Thanks !!

[@gwidwock]

Nice video. I enjoyed it. I just got an AR and this was very helpful.

[@rbm6184]

Good video. Thanks for the tips. However I sight a rifle in on a stable rifle rest and take my personal error out of the sight in. The most accurate way to sigh in a rifle is on a stable rifle rest regardless of the rifle. Thanks again.

[@BenCadorette]

RB M that's my favorite way to zero anything scoped. It makes for a one shot zero. One to see where you're at, adjust poa to poi, technically you could call it a day. I usually move poa to the bullseye, fire two more, usually the holes are in the right place and I'm good to go.

[@gregaxelson399]

Thanks Mike! Excellent video for we beginners....

[@Officer235]

Good video and good information. But I had trouble hearing over that wind noise.

[@bushmasterkiwi]

you where already zeroed for height /range first 3 shots , iron sight , as sight centre line , above barrel centre line . Best simple zero 25 yard 3 shot group 1 inch below point of aim . Which equals 100 yard zero 3 inches above point of aim (confirm if you have range ). So then a 300 yards your point of aim , will also be your impact point .Used this zero for years Infantry Rifleman RNZIR

[@janwilliams178]

Watched twice now I'm going to make an attempt at sighting in my iron sights. Thanks

[@armeddefender]

They deal with close quarters combat alot more than other units. For example, my world is mostly Air Base Defense. I want to be able to hit a target as far out as possible in that role. That is why I like the 25/300. It's simple, effective, and I can put rounds out to 600 with a carbine. If I am not hitting the target at that distance, I am hopefully suppressing and stopping forward movement.

[@charlesludwig9173]

All, the shooter here is not firing a 14.5 inch barreled carbine or a 20 barreled rifle. He is firing a 16 inch barreled carbine thus his rear sight does not exactly sync with velocity to yield a 300 meter zero from sighting-in at 25 meters with sight set at 6/3 or Z marking. Thus the shooter should set sight at 6/3 and then adjust front sight as needed for point of aim impact at 300 meters. The shooter should also learn MOA wind constant formula for prevailing wind velocity using the constant of 7 for M855 ammunition or the constant of 10 for Mk262. The formula for a 10 mph crosswind over 300 yards should look like this: 300 meters divided by 100 times 10 mph wind divided by constant of 7 equals 4 MOA or 12 inch favor. If wind is taken on rear sight instead of hold off then multiply 4MOA by .75 click value(carbine) or .5 value click value for sight on rifle. For rifle that would mean 8 clicks to windage drum . Ya got all of that?

[@robertesposito9871]

Great video I tried sighting in my AR yesterday at 25 yards at indoor range, but I Didn’t have a rest so I was just shooting from the shoulder and the best I could do was get shots on a 6”target with 3 bullseye so I guess I need to use a rest

[@dbrat35]

I'm new to the ar took to the rang expecting too shoot at 100 yards with a a2 delton sport , did not come close but after doing this that on your video it works good , thanks

[@robertmoran4841]

[@armeddefender]

I would use it with no problems. Cav-15 lower, RRA upper, Armalite heavy profile 1:9 twist barrel and front sight assembly with muzzle break, RRA rear A2 style sight, and KNS precision front sight post. Also have RRA BCG with extractor upgrade and one piece gas ring. ...no worries at all. :)

[@Longeno55]

25 meters huh? This is good stuff and couldn't be any clearer. A relatively new AR shooter like myself apreciates that and I'll try it out this weekend. It took me some time to sight in mine because I didn't really know what I was doing. Thanks!

[@MikeM0331]

I like a 100 yards zero for precision rifles because I adjust the elevation when I get out further. But for irons on a carbine I just zero for 260. I dont want to have to hold over the target with irons. Everyone has a preference.

[@duncan1482]

Sweet old Chevy!

[@shananagans5]

One time we were goofing off trying to do tiney smiley faces at like maybe 15 yards(indoor range) so I zeroed it for that range. Due to a bad eye I have to use an optic mounted on a carry handle so my optic is about 2 3/4 inches above the bore. After adjusting it to shoot 45 feet I was several feet high at 200 yards. lol I did make some mighty fine smiley faces though, I usually zero at 200 letting the bullet come up to the sight & I just keep in mind It shoots a little low under 200.

[@enterprise59]

Not to be negative, but I wish people who video out doors would cover or deflect the wind cause the wind noise is HORRIBLE. FYI, this is how I sight my AR's in as well. Former Army Reserves here.

[@jessethebaldyventura2391]

It's probably not a great idea to zero in that wind either.

[@sailingmj36]

Great video, liked it!!

[@91rxl650]

Nice job on the explanations. I had irons on my first AR and it took a little bit of getting used to the movements when sighting in.

[@leewithey2014]

[@bradebling8397]

Great informative video

[@plumberjoe80]

@millerusaf. I think in order for the 25 meter zero to be truly effective you need to be shooting 62 grain NATO spec 5.56 ammo. Like SS109. I think you will be slightly off at 300 meters due to using 55 grain commercial .223 ammo. It would be nice to see a follow up video showing how it does at 300 meters with the same ammo you sighted in with.

[@charlesludwig9173]

You will get good results shooting M855 or Mk262, even M193 because bc’s are similar to 300 meters. On the other hand the BDC feature is most exact from M855.

[@bblauter]

Had it on in the background, nice job

[@MikeM0331]

As far as the Marines go, I think a big part of it is that the vast majority of marines haven't shot rifles until they join. So they are all taught one method that generaly works in modern combat. I was one of those guys. But I feel I've been shooting long enough to find what works best for me. I use a ballist computer to find the optimum max point blank zero and use that for irons. I don't know about the Seals. I know that not everyone who trys out for seals were SOF beforehand.

[@hobertball3370]

Awsome range thier pardner Good shooting wind sounded serious USA 🇺🇸

[@ovi1013]

Nice I use the three shot method my self

[@thehoneybadger8089]

If you've ever studied statistics, you would know that a 7 round group would be the bare minimum, but the military is not that nitpick and neither am I.

[@bradebling8397]

I have almost that same rifle except mine is a old school Colt with the carrying handle.

[@g-radm3827]

Is it abnormal(barrel or front A2 sights) to shoot 10 inches to the right and 3 inches high @25 yard for a brand new Ruger 556, never been fired of sighted in?

[@Atlittle104]

Yeah, I think I might just leave it at that. I would rather my rounds go slightly lower in close combat ranges (Where you would be using iron-sights) because on a target with a profile, those rounds will still hit something like their lower abdomen where as a round going high could miss over their shoulder. Just my stance on "1-click higher"

[@w0cpm]

Not boring at all. I found it very informative and interesting.

[@Kekkon3n]

We used 3 rounds for 100m zeroing too in the FDF, but during basic training some crappier shooters had to use 5 rnds.

[@armeddefender]

Yep. I'm tempted to get another one sometime soon.

[@ratagris21]

Great informative video. I like these individuals who are arguing about shooting past 300 yards/meters without optics as the majority will go to an optic for 300+ shots. Up close this helps.

[@charlesludwig9173]

I don't use a scope since I can get good results with irons to the effective distance of the BDC sight.

[@underdog0731]

Awesome video. Thank you.

[@TheScotter84]

@millerusaf What zero would you recommend for a colt le6920, 16" barrel, standard iron front sight and "MOE BUIS" rear sight? I'm new to this so any suggestions would be appreciated.

[@stevenpierce4359]

I don’t blame you

[@tonyg4438]

Great class, thanks!

[@MasterBlasterRGR]

I was wrong--the bullet drop of a 5.56 is 12 inches at 300 yards--so it would make sense to raise your target approximately 8 inches above your shooting position to hit targets from 0 to 300 yards. There's a good video here of a former special forces sniper explaining this theory.

[@BennyBoombatz]

Thank you for posting video!! Have two questions. Are those the sights that came with rifle? Are you zeroing with small apperature or large one?

[@andrewgonzales1108]

Great Video thanks!

[@LaffyTheTaffy]

I'd like to add one thing! Whenever your doing your 3-5 groupings DO NOT lift your cheek of the rifle after every shot to see where it hit, especially for newer shooters who may not be as consistent with their position.

[@mike1022ls1]

Ya know i like watchin your vids.I even like the looks of your range you are lucky.One thing i notice is you have a problem with wind.Im going to ask if you have ever given any thought about the wind.Most of the time the wind blows across the mic on your cam that it gets hard to hear you.I have run into the same problem before I took just a small flap of cardboard and taped it on my tripod to keep the wind from blowing directly across the mic.Im just offering some advice that I have used myself

[@marvincderuyscher9676]

Great info! Thanks!

[@boofingdragon]

I geek out when zeroing a gun. Ill take forever just smaking sure it is perfect then i have to make a chart of POI at various distances shorter and longer than the zero range.

[@Sandhill1988]

Nice shooting 👍🇺🇸

[@MrZcruzer]

good vid! I'd been fighting my cheap iron sights and maxed out in down position shoots low every time, broke out the file and took some off the front sight post.

[@brentfoto]

Fine video. Were you shooting the M4 carbine? My question deals with the rear A2 sight elevation adjustment. What are you supposed to have it set at before you commenced zeroing in, and aren't you supposed to adjust it a click after zeroing in? I noticed that your target is also far larger than the M4 25 meter target also. Guess you have to estimate how many clicks will correct windage in comparison to the standard target.

[@ronernst3991]

Got a bag full of $hit, yet you have no sight tools. What's in the bag dad? He said Baghdad.

[@abbeyglencircle]

Great video, very helpful.

[@charlesludwig9173]

Let’s see what 4clicks will do? If you understood that your sights move in MOA then you would know the front sight click value is 1.75 MOA and the rear sight value is .75 MOA thus at 25 meters a click on the front sight will move bullet impact about a half inch and a click on the rear sight will move bullet impact a little less than .2 inches. The bottom line is let’s not see how much a sight adjustment will make. Instead let’s know what the sight adjustment will make.
