M4/AR15 zero setting. The most simple and useful distance to zero your 5.56mm carbine.

- 25 yards, 50 yards, 100 yards, what is the best zero setting for your AR15/M4 carbine? I recommend the 50/200 zero setting which allows you to make center-mass hits from the muzzle to about 250 yards. No holdover, on fuss. KISS - the simplest way to prepare your carbine for self-defense.
The Army trained us to zero at 25yds. The explanation was that the bullet’s trajectory crossed your line of sight at approximately 25yds and then again at 300yds. This was with 5.56 green tips and M4 carbines. For everything in between, they instructed us to aim low on the target because the round was above your line of sight. Worked well enough for most of us to pass the rifle quals. I suspect that Ranger/SF had much tighter tolerances for their shooting.
Belt buckle hold at distance and you punch center mass with the zero mentioned. Russian doctrine is similar with the AK. Rob on AK Operators Union has great videos on this. I get what this gentleman is saying and he's right...in a way. If YOU zero your rifle and YOU understand the holds, bullet drop/rise, it becomes a preference.
When I was in the army (M16A1 era) we zeroed on a "Canadian bull" target at 25 meters and the "X" for the point of impact was 1 inch below the aiming point. That gave us combat trajectory out to 300m, then flipped the L sight leg for 300-500m, basically what you spell out. Since I left my 11B days behind a long time ago, I don't think I need to be prepared for a 300-500m shot.
Great video sir, I have my AR zeroed at 50 yards as well for pretty much the same reason. I run 64 gr soft points though in my rifle for home defense. I rather have that guaranteed expansion and a lil more penetration with the heavier weight bullet. Thank you for all the great info!
Thank you for sharing your experience and knowledge.
Great info and I really like your lessons. Keep up the outstanding work that you do.
Thank you.
Another very good video. Thank you.
Mils are simply 3.6 inches at 100 yards. Which means each click is .36 of an inch at 100 yards so once you know that you either dial FOUR 1/4 MOA clicks to move, 1 inch at 100 yards or three Mil clicks to move 1 inch at 100 yards. It truly doesn’t matter as long as you keep your unit straight but, MOA is a finer system even if it’s not in vogue with tacti cool
Ops I did not listen long enough
Man 😂I love this guy
Sorry, I'm married.
This is interesting in that we both use the same method, only with different means of measurement. Whereas you work in yards, I work in meters.
At 74, after cataract surgery in both eyes, my distance vision is perfect. But it's blurred up close, thus optics are useless to me. My only AR15 is a stock 16" M4 clone with the f2 sight up front and a carry handle rear. And load my own 55gr 5.56mm ammo. Very basic.
I zero for 200m (roughly 219 yds), and close zero at 44m (48 yds). This works out to 1.9" high at 100m, and zero at 200m. Setting my max trajectory height at 2", this works out to the 200m zero, and a max point-blank range of 229m (250 yds). Or, 1.7" low at that range.
Where I live in the woods of E. Texas, are crawling with feral hogs and coyotes. The hogs trash everything, and the coyotes kill livestock and many of the dogs kept on my neighbors, and my own property. Though primarily a levergun sorta guy, I've found the simple AR15 setup is ideal where my longest shot might be well under 100m. And engaging a pack of coyotes with it makes it easier to shoot several when encountered, as opposed to my somewhat slower pistol caliber leverguns. 😏
Really enjoy your work. Being an old retired peace officer and gunsmith, I can easily relate to your thoughts on many subjects. Thanks for letting an old man ramble.
Thanks for passing on your knowledge! just scored both of your books and have been reading them. this vid was excellent. keep making videos becuse you are passing on Expert knowledge for those who are seeking it like myself. this one really helped me because I like the detail used in these videos and i just happened to save up and buy my very first carbine recently. I got the one I really really wanted a Bushmaster XM15-QRC. i havent owned an AR since 2000, which was also Bushmaster but it was the M16 A2 style.I had to sell it in 2003 i was bummed!! I also put a red dot on the carbine and have almost zero experience with red dots. I tried a red dot on my kel tec pmr 30 and could not adjust to it at all. then I bought a S&W M&P M2.0 9mm and have become so comfortable with it there is no way I would ever put a red dot on it. but on the QRC I want to learn and become skilled with the red dot only I have no front site post. i bought some flip up sights so im going to take Dicks advice and get those sighted in first.
Thanks for the kind words. Shoot straight and stay safe!

I too zero at 50 Yards but make no claim to having a great mind.
Nor do I.
Dick,
Thanks for the video. Very good information.
Glad it was worth watching for you.
You supposedly get less penetration from .223 thru interior walls than with buckshot or pistol rounds....
I have one of my AR's sighted in at 50 yards. The other at 100 yards. The former is a 16" and the latter is 14.5" with pinned flash hider. Looks like you recommend the 50 yard which makes sense to me. Dick, you sure that wasn't a Commodore Color 64 computer? It was available at the same time as the TRS80 (Tandy) commonly referred to as that trash 80. I remember those... I took programming class in HS and we would punch our programs on cards and send them off to the local community college to be debugged = they'd come back with red cards to mark the bugs.
Nope, Atari 64. Bought on the advice of my Army Chaplain buddy because he sent me about 30 floppy disks of programs and games. The TRS80 (4k RAM) was my first home computer.
36 yards is the absolute best range to 0 your sights. That military taught 25 yards but mathematically 36 yards is better
36 is better for military folk who may routinely work out to 300 y/m. For civilians and police patrol rifles I recommend the 50/200 zero for a lower mid-range trajectory and a better fit for their likely ranges.
HELO makes a great round out of Fla.
Please, lower the intro music. Good info video. Practical.
I did lower the music volume some, I'll take it down a little further. Glad you enjoyed the video.
36 - 41yds
If you plan to work out to 300 yards or more, the 36 is popular with military SpecOps folks. For cops and civilians, I like the 50 yard zero, which puts you on again at 200 yards.
@@lockloadwithdickfairburn-cr1jb I've got the 16" stainless steel carbine with scope and dot and out to 300yds the 36yd zero is the best compromise. However I recently got the A2 clone with carry handle sight and 20" barrel, and the calculator says a 39yd zero is best (which I haven't tested). But because I really can't see past 200yds with open/iron sights the 50yd zero does seem more practical. And to be honest I enjoy shooting the A2 more because of the nostalgia and simplicity.
What are your thoughts on the .380 for defense?
My wife carries one almost daily. I carry one if I feel the need for an ankle backup to a larger belt CCW, or when in dress clothes. I think the .380 is generally the minimum caliber you should carry, unless someone is physically incapable of working the slide or pulling a DA revolver trigger. But, with the right load it will do OK with solid hits. I think the Lehigh Defense FTM bullets are the best, I use Black Hills Ammo's Honey Badger load.
