All the more reason to be methodical in your zeroing process, as Aaron advocates. Tip: After zeroing for your carry ammo, get a good quality boresight laser cartridge, determine where the laser dot is with respect to your red dot optic at 25 yards, and make a note (usually they don’t exactly match up). Then, when you need to re-check zero (after an RMR battery change, for example) you can use the boresight to re-check the relative zero (relative to your actual red dot) and get closer with less ammo. In three years doing this sort of thing, I have yet to see any real zeroing change from mounting/dismounting RMR’s with well engineered mounting solutions and a calibrated torque wrench (using plates with precise RMR posts, mill jobs with precise RMR posts). Plates without posts, or direct-mill jobs without posts, or free-handing the bolts, will often require an actual re-zero. YMMV.

[@chtomlin]

@@shinigami1925 why is the red dot zero different from what you co-witness with iron sights? (sorry for the dumb question) I'm guessing it is related to how you shoot vs where the sights point, but that would require your shooting to be very consistently away from where the sights line up, wouldn't it?

[@shinigami1925]

@@chtomlin Irons are regulated for 15 yards in my particular case. Some folks roll without irons at all (many gamers). So the bore laser solution is an independent means to solve the issue with less ammo.

[@novalelapena6170]

In my experience, if you carry Federal 147 gr HST standard pressure than you can use speer lawman 147 gr or American eagle 147 gr (I believe they are they same loading - just different brands from the same manufacturer) for the intial zero and then only need to make make minor adjustments with HST, saving a significant amount of premium carry ammo. In the long run it may be worth finding a range ammo that performs similarly to your carry ammo just for this purpose.

[@ryanpeck3377]

Good tip... Fyi, Speer and American Eagle are brands owned by Federal Ammunition, which of course makes Federal HST as well.... Federal does now offer a “train and protect” package which gives you training fmj and hst of the same weight and is supposedly the same trajectory/velocity etc.

The illustrations are a great idea. I've had a few people ask to look through my RMR equipped G19 at some local matches. First thing they do is line up the irons and comment that the dot is below. I try to explain. Still amazes me that people who couldn't imagine shooting a carbine without a dot can't open up their minds to shooting a pistol with a dot. I don't even waste my breath anymore, and exclusively refer people to your videos, whether it's for techniques like this one or tests of various dots.

[@f308gtb1977]

I know someone who at first thought he had to flip up ONLY the front sight on his carbine to shoot, thinking he was supposed to put the dot on the front sight post to aim. It only took one shot after I had him lower the irons to see they were irrelevant when using a dot, so at least he wasn’t stubborn whatsoever, but still, who told him that?????? My point is just that yup, there’s a ton of confusion about optics out there, even decades into red dots.

[@cobrajack-official]

I put 1" orange stickies on a target. Walk up to 3yds and shoot a few rounds (don't bother cowitnessing). Make COARSE adjustments. Check with 1-2 rds. Make another correction if necessary. Back up to 5yds, recheck. Adjust if necessary. At this point I'll back up to 15 or 25 for my final zero. The final zero I do just like you, from a flat top using a bag, 5-10 rd groups. The biggest difference is dealing with the frustration of trying to sight in a red dot from 25 at the beginning. It's hard to even see the hits at 25 (binos are good to have). Anyway, I tell people just start at 3yds and work backward. I'm convinced its quicker and less frustrating.

Can someone explain what causes the dot to move up in the glass at 11:15 or so. He shows the final sight picture and now it’s centered in the glass and not slaved to the front sight post. I just don’t get what causes this to move up in the window. If I have my irons properly lined up my dot basically sits slaved on my front sight post. Is it simply the increased distance that when you’re zeroing the dot causes it to move up?

[@anubisgodofgods]

I got into pistol red RDS a year ago. I couldn't tell you how many people say that to co-witness the dot to the front sight is the correct way. I never did agree with that for all the reasons you stated. What I like best about RDS on different pistols I own is that the POA and POI is the same for every gun. With iron sights I have guns with a combat hold, center hold and my adjustable sights a 6 O'clock hold which I prefer. With a RDS I use the same hold on every firearm.

[@codyneedles6461]

So I think I misunderstood when I went to zero my 507k on my hellcat. I slaved the dot to my front post and then kept lining up my iron sites when I shot and adjusting. If I understand it correctly now, I should slave the dot to the front post and then center the dot in the window the best that i can and forget about the iron sights and adjust from there. Correct

[@tv92taylor]

For those wondering why the final illustration shows the dot high above the perfectly aligned iron sights, that is because the illustration is incorrect. The front sight should be slightly high in relation to the rear sight. The dot and sights would line back up if the pistol was slightly aimed down. It’s all a matter of perspective based on where the eye is in relation to the pistol. I posted this explanation in another thread: The final illustration is inaccurate because the iron sight alignment didn’t change, but the dot alignment did. The front sight should be slightly above the rear sight when the dot is up in the window. The dot is moving up because the pistol is being aimed slightly “up”, but the eye level is going with the dot. If you use a rifle with lower 1/3 irons, the same thing happens. You CAN perfectly co-witness the irons with the dot, but when actually using the dot, the irons will not be part of the sight alignment anymore.

Perfect timing, I’m going to set my new carry pistol this way. Another thing to mention.

You can then see if that brand makes defense ammo (jhp). You would be surprised how many people run one ammo brand and assume the firearm is inaccurate.

Kinda confused about the vagueness of centering the dot in the window after slaving to irons. Doesn’t this slightly change presentation or are irons still aligned and dot is center of window and a different zero distance than the irons?

[@stampstepper2393]

The age old question nobody answers!

[@benjamin3615]

Slaving the dot to the irons is a starting point, but you need to know the point of impact for your iron sights. So, if I toss suppressor height sights on my pistol, and go to the range and test them out. I start at 3 yards and wind up at 15 yards and I'm dead center with irons, then I now know the point of impact is 15 yards for irons, so by slaving the red dot to my irons, I should be able to be dead center with my dot at 15 yards. However, I don't want to zero my dot at 15 yards and would rather be zeroed at 25. This is where the dot becomes completely independent from my irons. Since I am no longer at 15 yards, aiming with my irons will not let me hit the bullseye. I know I'm on paper at 25 yards because I was bullseye at 15, so I adjust my RDS accordingly until I am zeroed at 25 yards. Now my irons are set for 15 yards and my RDS set for 25 yards. They are independent from each other. Centering the dot in the window is for when you're shooting using the RDS. You do not align the iron sights when aiming with the RDS, only presenting the dot in the center of the window. Like mentioned above, it is independent from the irons, so as long as you can see the dot, put it on your target and pull the trigger, you should hit what you're aiming at. When you look down the irons, the dot could be anywhere. When I look down the irons on my gun, the dot is actually exactly right on top of the front sight dot. It is zeroed at 25 yards.

Going from standard iron sights to suppressor height sights and a rds is a big change in zeroing.I find myself struggling to get it dead on i might be expecting too much of a precision shot and for one since the suppressor height sights i haven't declared where they're zeroed at might be my problem my setup isn't co-witness at all but it's as good as I can get it at the moment.

[@typhoon186]

Unless I'm missing it, it appears you must be able to co-witness both front and rear iron sights through the red dot in order to slave the red dot to the iron sights. In my case, once the red dot is mounted, I cannot sight with the rear and front iron sights.

On my next trip to the range, I will re-zero the red dot reflex sight and start with placing the red dot on the front sight and then when I bisect the dot I'll move on and continue the sight zeroing process by placing the red dot in the center of the lens window so that I will be able to shot by centering the red dot in the middle of in the window and place that red dot directly on the target.

@@k9rka489 does that mean that when you are looking solely at the dot which is high up in the window above the iron sights, that your iron sights would be in an incorrect position (meaning that your iron sight picture would result in high shots off the irons?)

[@AndrewAcosta82]

Yeah I’m confused too.

[@k9rka489]

MusicMan1eAnda There's quite a bit of science behind it, which is hard to follow. The white paper Aaron has on his website goes deep into it. Your red dot and irons are mechanically at different heights when installed on the pistol. When shooting remember the red dot isn't actually moving in the window. It's more your perception and the brain translating it as you should have both eyes open. It can take between 500-1000 draws to start gaining proficiency with it. Again, think how long you've been shooting irons. Depending on the shooter, it can take you just as long to be proficient on the rds, although most pick it up faster after several years of irons use.

[@Bionic_man09]

I may have missed it, but can you please explain why in your sight picture/views from making adjustments that the dot gets lower and lower on the front sight post and then in the final view picture, it’s significantly higher than the front sight?

I had to watch the video a few times to understand but he co witnesses with his red dot to his irons before he even shoots to basically get the windage and save ammo. On his first 5 rounds he doesn’t co witness he just uses the dot. The co witnessing or slaving he does as his first step isn’t fired like that. It’s just a preparation before zeroing to save time and ammo and get close to a zero.

[@62dobie]

I was good till the Final Zero Dot Position In Window. All the time you’re zeroing the dot, your below the front post, even when you say it’s zeroed, then you move it up at the end after you finished. I don’t understand this point. Will someone please help me with this.

[@LukeInTheWoods]

BIG LOU I think he was just showing where you start when you slave the dot versus where you end up when you’re fine tuned. He was showing that there are some significant adjustments that are made even once the dot is slaved.

[@jackryanacuna1763]

I feel you BIG LOU, I was lost after the last part having the rds in the middle window..i guess it just eliminates windage? And then it's a while new adjustment when the rds is brought in the middle window?

[@jackryanacuna1763]

@luke galindo so, Aaron is just basically centering the rds and finally when you bring it up to the middle window, it's a whole new adjustment?

[@62dobie]

@@jackryanacuna1763, what happened was, after he zeros the red dot below the front post, he tilts the gun up till the dot is in the middle of the window. The picture he shows is wrong. The front site should be lower in his final picture with the dot in the middle of the window. By tilting the gun and making the dot in the middle of the window, it is still zeroed, now you are JUST focusing on the dot only. No matter where that dot is in the window, be it top,side, bottom or in the middle, it will still hit what that dot is covering because the gun is now zeroed to that dot. This is what makes the dot faster. Remember, his illustration was wrong on his final adjustment when the dot moved up. He didn't adjust the irons in the picture. Hope this helps. I tried to be as detailed as I could be. Ask anymore questions if you need any help.

[@jackryanacuna1763]

BIG LOU so the fine tuned should look like "rear iron sights are lower than front post or maybe hitting right in the middle of it while red dot is in the middle window" if you're using rds..did I get it right? So the picture shouldn't have your dot in the middle window while the rear and front are all leveled, is that right? Thanks for helping out..I'm new to this and it's frustrating at the range😓

[@blackpearl_z71]

Aaron, thank you so much for this video. Lots of great info, answered every single question I was thinking of to zero my RMR equipped Glock 19 MOS. Thanks again, and keep up the great work.

[@walterw8146]

Awesome video. Extremely informative and common sense!

[@chogmack5822]

Watching these videos help again and again. Where are his recent vids?

[@silencerbear9347]

124g nato 9mm has almost the exact same POI as 124 +p HST. Maybe an inch off. For anyone out there not wanting to spend 30 bucks every time you change your battery. Obviously verify with your carry ammo.

[@f308gtb1977]

Good tip, thanks.

[@kylewheeler2150]

I still don’t understand how you get your red dot in the middle of your sight? So you put your red dot on top of your iron sights. Then you shoot 5 rounds and adjust as need.oerfect dandy, your shooting right where your red dot is. But just like in this video your red dot is half way down your iron sights. How do you get your red dot in the middle of the window in your red dot? Thanks for the help in advance.

[@SageDynamics]

Kyle Wheeler that’s where the dot is when I use it. The iron sights aren’t referenced at all.

[@dollabill4804]

I’m lost to you bisect the red dot shoot five rounds and adjust from there right

[@musicman1eanda]

@@SageDynamics so you're saying when you are viewing the dot high up in the window, that your irons will essentially be positioned with your front sight post high in relation to your rear sights? So if your dot goes down then you have to adjust the gun back downwards in order to get an accurate iron sight picture?

[@SageDynamics]

MusicMan1eAnda more or less. It varies on gun/sight radius and chosen sights.

[@sneakybooget9188]

@@musicman1eanda I done get why he just won't answer the fucking question, did you ever figure it out?

[@fu4616]

Just returned from zeroing my 10mm, or at least attempting to zero it. It's close, but still needs work. I was getting tired and sloppy. Wish I had found your video before I left.

[@anthonybarrett8454]

I don't understand what he did in the end. He started with the lolly pop and then moved the dot down more twice raising the point of impact. After he got it zeroed, it shows the dot moving from that position to center. How did he raise the dot to the center of the screen? My red dot only has elevation and windage.

[@HorsepowerDr]

Im alittle lost here .... after the first 5 shots with the dot co-witnessing with the irons and point of impact being low you said your adjusting up of course but on the sight graft with the irons showed the dot getting lower n lower on the front sight post with each adjustment but then at the end with the gun sighted in the graft showed the dot well above the irons in the middle of the window.... im not understanding how it got there like that going by your grafts on the adjustments ...what am i missing here ?

[@TerminalM193]

You don't ever want your main zero to cowitness with the irons. That completely defeats the purpose of the optic in the first place. The only reason he started with an iron witness was because he didn't want to chase paper. It's just a simple starting point that's guaranteed to get you within the area you need to be. You want a single aim point when using the optic, the irons are simply for the EXTREMELY rare chance that your optic for some reason isn't working in that super rare scenario of a life or death situation, that's it, that's all.

[@musicman1eanda]

How do you get the dot way up into the center of the window like in the 1/3 cowitness in the last photo? Do you angle the gun with your hands to change the position, move your head, or is the dot position moved by adjusting the optic with the zeroing mechanisms?

[@Doitallgp]

MusicMan1eAnda the former

[@VintageGold]

@SageDynamics - I'm a new shooter and bought a G19 Gen5 MOS with the intention of learning iron sights and then putting on an optic. Based on your experience, would you recommend I put the optic on right away and start learning the pistol that way instead? I understand the fundamentals of using a pistol don't change (grip, stance, sight picture sight alignment, breathing, trigger control) and that the biggest advantage is allowing the shooter to threat focus. Thanks in advance for your feedback

[@sethrich5998]

VintageGold There’s pros and cons to both. By starting with optics you remove one of the difficulties which I think helps very new shooters get the basics of grip, trigger press, etc. Although once they get the basics down I recommend going to irons to continue development, it’s hard to go back to shooting irons once you get the dot down, it’s a good skill to have though. I learned pistol all irons, and rifle with optics. I can honestly say I’ve never gone back and gotten good at rifle with irons. I imagine if I started with dots on pistols it would be the same. Kind of like learning to drive a manual or an automatic first, it’s going to depend on how you learn best.

[@eTSnipinn]

Great video took me a little bit.. but i have her down now… Thanks for the video.. 1 1/2 inch groups 25 yards .

[@Tiktockkk]

So when you say you do not use the irons again once slaved for a start, and use relaxed window with centering red dot to glass…. Would that mean the iron sights no longer have proper sight alignment or would they still align?

[@Tiktockkk]

Also asking because the final visual representation still shows the iron sights aligned when zeroed and show red dot centered.

[@jakemerica]

Good info. I was confused the other day at the range on how to properly zero the Holosun 509t on my FN 509t.

[@BryceLyt]

Hey Aaron awesome video. I've sighted in two RDS sights and followed your instruction to do it interdependently. I was confused though on the final zero dot position in the window animation since before it was on the front sight post. Howd it get back to the center? Were the other illustrations just what the adjustments are doing even though the dot remained in the center?

[@SageDynamics]

Bryce Litfin the final animation shows the dot position when used. There is no need to align iron sights when using the dot, such as co-witnessing. This is why the optic is zeroed without referencing the iron sights.

[@KingAlovarxe]

@@SageDynamics So what youre saying is when my rmr is zerod at 25, when aligning the iron sights the dot is in the FSP. Like almost where the front dot is. That can be normal and ok?

[@SageDynamics]

Johnny Yackle correct.

[@KingAlovarxe]

@@SageDynamics awesome i felt like I was doing something wrong. If bench rested with this zero i can push 100m shots with a slight hold over and hit 5-30m with no issues but when looking at the graphs I felt like im doing something wrong.

[@sneakybooget9188]

Bryce I'm still confused on the same thing you were, he got gradually lower from the first to the 3rd adjustment but on the finalized view he shows he's in the middle of his glass and not making contact with his front iron sight at all so how did he finalize his nonslaved zeroed position?

[@GKUZYK1]

Great video and informative. I just received my first red dot for my Sig firearm and looking forward to taking your advise here on sighting it in.. thanks and look forward to others that you can help us out along the way to good shooting

[@krisackenback240]

So i noticed in the picture where it says "Final Zero Dot position in Window"..is that where my dot is suppose to be the whole time while im zeroing my gun?....i gues my question is how does the dot end up there if id already slaved my dot to the irons?...does my question make sense?

[@Hdic2018]

I’m wondering that too, I just got a new pistols and optic need to zeroing

[@wavelengthdesigns]

I know this is an old video but leaving a comment because maybe I am missing something but I'm a bit unclear about how the dot goes from the middle of the front sight post to the center of the window when it stays on the sight post through 2 diagrams prior. Previous handguns I've had dots on, the dot obscured the irons entirely but my recent Canik MC9/EPS Carry combo has me confused because the irons are visible through the window. I'm assuming that the dot after adjustments will put the irons out of alignment if you have a correct sight picture due to the differing planes? I'm probably overthinking this.

[@easbreid9879]

What about using a bore sight instead of slaving to your irons for a basic zero? The reason I ask is bc I have a 9mm luger bore sight just to make zeroing easier for the few 9mm carbines I have

[@longshot7590]

THANK YOU!!!! Just picked up a SIG P320 X carry with a factory Romeo RDS at a steal right before the shtf with the Chinese flu and need to zero the thing - your video is Just what I need, especially now that ammo availability and cost are in the critical zone again!

[@currybob551]

I am a fan of your reviews and take your information to hart because of your extensive experience. I also feel your reviews are some of the most professional and informative I have seen anywhere on you tube and I have seen many. Your red dot info has been a huge help for me with my recent Wilson Combat order for a EDC X9 with a red dot system. I also sent in my WC 45cal in to have it machined for a red dot also. I'm older now, eyes are not as sharp as they use to be and love the targeting ease of the red dots. I went with the RMR type 2 for both and I'm anxiously waiting for their arrival. I originally ordered them with the Trijicon RSO, after I saw your review of the RSO, that completely let me know that was not going to work for me. I don't carry these for duty use but still want the most durable systems I can find. Again, love your work and thanks for sharing your expertise to a novice but working to improve that.

[@gerryc1982]

Hi. In the graphics you show after every round, you mention the clicks on the red dot, yet we continue to see the dot on the iron sight up until the end when we see it in the middle of the optic. Not sure I understood if you continue to zero on iron sights thru the process or not ? Thanks

[@chltmdwp]

Same even more confusing how the dot suddenly moved so far up

[@yaddi3434]

I'm new to red dots. Just got an rmr type 2 3.25. I'm confused by the pics you put up as you started zeroing. The dot was going down down down in relation to front sight and then all of a sudden it moved up like an inch, to the middle of the window at the final zero? What am I missing?

[@Mugennunez]

Matt T that’s what I’m trying to figure out also lol

[@musicman1eanda]

Have you figured it out? I am confused as well

[@yaddi3434]

It's still confusing bc the dot moves based on your view but I think I'm zeroed with the dot in the middle of the window.

[@ikemouser2580]

This only works with RMRs to my knowledge, I tried it with a 508tv2 and theres no way to get the dot low enough to touch the front sight post, it doesnt even come close even with it lowered all the way.

[@SectionChief]

Using suppressor heights sights, your 508T elevation can’t be lowered to touch the front sight?

[@jackryanacuna1763]

I run holosun 407cv2 with suppressor sights and it goes all the way to the middle of the front sight..i just don't get bringing it up towards the middle of window independently, wouldn't that just lower the POI?

[@dingdongdaddy589]

Good info. Thanks for the reminder to check your carry ammo. 👍🏽

[@getfragged7051]

I just want to clarify, so after the first adjustment from a “slaved” red dot he’s using the red dot alone for his poa? Correct?

[@TristanPetricca]

Yes
