How to Reset your Scope to Optical Center
ฝัง
- เผยแพร่เมื่อ 8 มิ.ย. 2020
- If you've ever taken your elevation or windage to the extreme and tried cranking the magnification, there's a chance you've been scraping the erector (inner tube) against the inside of the scope's main tube. Now would be a good time to move that inner tube to the center of the outer tube, take the pressure off the walls, and re-zero from there.
For internally-adjusted scopes, the process is pretty much the same.
1. Walk the scope up (elevation) and to the right (windage), taking the pressure off the internal spring.
Keep going until you've hit the limit on both, stepping each a few MOA at a time to avoid damaging the erector unit.
2. Now, look up or estimate the total amount of travel each of those turrets will have.
Divide that number in half.
3. Dial the elevation and windage down to that halfway value, stepping each one a bit at a time - like putting a car tire back on.
4. Done! Now go ahead and work the zoom, make sure nothing is sticking, and then go re-zero your scope.
For example, one of the scopes has a total adjustment of 50 MOA on the elevation and windage. The middle would be 25 MOA. Move the windage all the way right and the elevation all the way up. Then step down and to the left, 5 or so MOA at a time. Once you've gone down 25 and left 25, you should have the erector unit (inner tube) floating in the middle of the outer tube (scope body). You should have your full range of motion back, and this provides a good baseline to re-zero from. Plus, it tends to free up stuck magnification rings.

I installed this optic on a crossman 760 air rifle.I have now shot the riffle around 500 times during target/plinking practice, and the th-cam.com/users/postUgkxc4K63Fd5LglDMObu7-Bgapxp_ef0W8hE scope has done well.With this optic, I have neutralized around 30 pigeons that were invading one of my buildings.For my short range air rifle, I will continue to use this scope, but will be upgrading to a more powerful scope, when I buy a more powerful air rifle, in order to shoot at longer distance.For the money I have spent, this scope has truly been a great buy.
Thank you , very informative. You made it clear on what happening on a Leupold 3x9x50 . When I want to move to the left I have dial to the right. When I want to go up , I have dial down . You explained and clarified what is going on with the internal mechanisms. You have a new subscriber.
Thanks for the info. great stuff to know
Very informative brother! 👍🇺🇸
@Cecil Hidalgo you're right! Nobody cares
thank you for answering my question. i just got a new arken ep 5 and the zero stop was adjusted all the way to the bottom. it just didn't seem like that is proper. thanks again.
Thanks alot brother you are a big help much appreciated.
Carlos Hathcock would be proud of your demo scope.
Great Vid...
Excellent '' Great Video , Many Thanks
Tanks is Wassim helpful 😊
Very important and informative, thx
Thank you Cliff. Also, if you have any recommendations for videos you'd like to see from us, please let us know. Respectfully, Corbett Leatherwood & the Hi-Lux Team
Not really. I mean if you relax it by moving to the extreme relaxed position, then you adjust to center, what happens when you re-sight it? Won't it just have to be moved back to the original spot, where you were when it was zeroed? Seems like it to me, but there's no explanation as to why it isn't. Or if you have to move the actual mount to compensate. Not very clear at all.
@@scotthoover6689 this is exactly what I was thinking. This leaves me feeling confused for the exact reasons you stated.
Thank you. For this video
Our pleasure. Glad you like it.
Ya I was having some problems I think this video help but I ain't put my scope back on to see
Hi expert why my scope i view the images not stabeliz move around??? Thks expert
Is this really necessary? Let's say the windage and elevation are already maxed out one way or the other. When you fire your first shot, it will be way off. So you position the crosshairs over the impact point, then adjust your windage/elevation so that the crosshairs are over your original aim-point (e.g., center bullseye). Done... the scope is calibrated. If for some reason you have to turn the dials back to the extreme to get it sighted in, then there's something else wrong... perhaps with the way it's mounted to the rail. Am I missing something?
you should keep aiming at center and move the reticule to your first impact.
Are you saying the barrel is bent my owd?
Just wondering with a second hand riflescope, if there is a way to, or a need to find center?
How do you reset vortex tactical
Very interesting video. Unfortunately didn't solve my windage issue. I'm still at the maximum windage but still can't adjust the Poi. Did I dammage beyond repair my optic (Vector Veyron) ?
Without looking inside the scope, that can be a little difficult to determine. There's also other possibilities - the most common being that the rail might not be installed in line with the bore.
Nice presentation. I cannot find the number for MOA adjustment for my Hi-Lux 2-7x32. I count about 160 total clicks from stop-to-stop. Guessing 80 to center.
Wow. I carefully rechecked the counts and got 80 total MOA adjustment. Halfway in is 40 for both elevation and windage.
Not sure where the 160 number came from, I was careless in spinning the turrets a bit fast I think.
Thank you but 1 thing is still not clear from the video. I'll take elevation only as an example so correct me if I'm wrong: the spring is below the erector tube and the turret above it. So to relax the spring the turret needs to be turned outward/up. The direction as you says is left/counter clockwise. However, if you think about it, that is the same direction as when you want to move the point of impact UP as written on the turret. But this is the same as moving the reticle down! So the erector tube is moving down?? Confusing. Thanks for the help
Looks like it has been 5+ months since you asked your question. Did he/they contact you or just never read or just ignored your remark?
@@REDARROW-ez7dg Thanks for your reply. No, I didn't get an answer.
Yes you are correct I think. If you clamp a scope in a fixture and adjust poi up the reticle moves down and vice versa
The answer you need is as follows: the marking "UP" means "the direction in which the point of IMPACT is rising". So, effectively, by turning the knob in that direction, you are "upping" the muzzle (pointing the muzzle higher). Accordingly, when turning the windage knob to the "Right", you are moving the muzzle to the right (and vice versa).
My erector unit hasn't been working right for the past few years, no matter how much I rub it against the sides. I really need a factory reset.
My problem is that. #1 I'm using a red dot bore lazer As my target point.
#2 logically I figured on adjusting crosshairs to the red dot.
#3 the hairs don't move any direction.
Is there an internal problem that can be addressed?
Sounds like one of three things could be happening:
1 - If the laser and scope are pointing at something very close, the change to your crosshair position may be too small to notice right away. 1 MOA = 0.1" at 10 yards. You'd have to dial quite a bit!
2 - The scope may not be able to adjust for a close enough distance. If this is the case, the turret will likely hit a limit and stop rotating.
3 - The scope may be damaged or broken in some way. This is especially the case if the scope hit the limit (mentioned in #2) and continued being dialed.
This video was helpful. But the problem I am having is the sights on my rifle scope are reversed what I mean by that the elevation moves right and left the windage moves up and down. Is there anyone out there that can help me with this problem pretty crazy!
Hi Don, some rifle scopes (like our CMR4) have the windage positioned on the left side of the turret block instead of the right side. I would recommend that you check your riflescope's manual to confirm the position of the windage turret.
@@christopherwu814
thank you for your reply Christopher. when I first bought the rifle scope everything works like it should the elevation was on top of the scope the windage was on the right side of the scope. When I started to sight the scope in all of a sudden it reversed on its own so the elevation on top start going right and left and the windage on the side started moving up and down. That's what it's doing now brand new scope I bought from Pyramyd Air
@@donjones7298 I am seeing something similar and I am guessing it's all due to the subject of this video, I think you'll find you've "bottomed out" one or both of your settings which is why I wanted to know how to get back to zero again as I'm sure that's what I've done as well.
Your scope is just turned like 45⁰ in the scope rings. So it make up and down left and right, and right amd left is up and down. Just loosen your rings and turn it until the turrets are positioned the other way.
Once re-centred, when re-zeroing would you adjust windage first before elevation?
Honestly? Dealer's choice. Elevation is usually the way I go; Winds change, but gravity is a constant.
Hi guy I purchased a 6-24-50 from Monstrum I turn the turrets NOTHING happens to cross hairs,I returned it,and the new one does the same thing ? what am I doing wrong, also I tried to lift the turrets while turning what can I do ?
The reticle should always appear to stay at the same spot in the glass (the center). The real way to test is to take your setup to the range. Put your crosshairs right on the center of the bullseye, take a shot. Turn the elevation knob a large amount (maybe a full rotation), then put the crosshairs on the bullseye and shoot again.
When you're dialing, you're not repositioning the crosshairs inside your sight picture. You're repositioning the sight picture itself - which can be quite difficult to measure when just holding the scope at home.
How do you know how many times to turn the turrets to return to center? For the Scout, you made 5 rotations on each turret at .25 MOA, for the MDT, you made roughly 4 rotations. What math are you doing to know how many times to turn it? Additionally, what nunbers on turrets are you referencing and what are they telling you?
That all depends on the specific scope. Each scope will have a certain total amount of travel, which should be listed in the manual somewhere. I turn the turret half of the total travel (e.g.: If a turret can make 4 turns in total, halfway would be 2 turns).
The markings on the turrets can also vary. They'll either be in MOA or MIL. Turrets marked in MOA values typically are 1/4 MOA per click, though older scopes are sometimes 1/2 MOA. MIL turrets are typically 0.1 MIL per click. The turrets may have a different number of markings/clicks per revolution.
So to do this, you'll need to know: How much adjustment the turret is capable of and what unit/value the turret is marked in.
I did not understand: OK, you "centered" the inner tube, thus relieved it, but, now that you've got to (re)zero the scope, you got to move the reticle, most likely putting the tube (and the reticle) into the previous position (same position it was in, before "centering")???
Thats what I was thinking as well.
Do you repair scopes if so please send me info I have a scope on a old 22rifle that has turned cloudy and would love to have it fixed
Unfortunately, we only repair the scopes we've made. But Ironsightinc.com repairs other old scopes!
I will sight in my M1200 next week
We're looking forward to hearing about it! Have fun out there.
How did it go?
I put the scope in a v block. Put a dot on the wall. Put the cross hairs on the dot and rotate the scope. Then adjust untill the cross hairs are on the dot.
Is there a video that shows how this done
I don’t understand so if your scope is zeroed and you find the middle only to zero it again it’s back to where you started right? So why do it?
If your scope is zeroed and is functioning fine, there's no point in doing this. If your scope is zeroed and suddenly no longer adjusts (or could never 'reach' the zero), then it's time to do this. Reset the scope, then you can see how far off it's pointing from the expected midline. Doing this can also return function to otherwise stuck dials if you're trying to zero to a new target.
Didn't know Giovanni Ribisi was into guns.
😊
Good video, but this is "Mechanical Zero" not "Optical Zero"
I’m confused😂
Totally worthless video because I can not find any info on any of my scopes where they say how much adjustment there is, new or used!
So how do we make this adjustment then?
Then it requires a bit of experimentation - run each turret to the lower and upper limits by dialing them in the usual way and count the overall travel.
Which model of scopes are you trying to find info about?
@@HiLuxInc Barska 4×32 illuminated reticle #LVK1-AC11876 I got for $38 and a couple of the skinny little rimfire ones that are variable power, Bariska 3-7×20 #AC10003-JCH4 for $16 both were on clearance at Blains Farm & Fleet in Oswego Illinois.
I even tried that "hold them up to a mirror" technique and all I saw was darkness other than the rimfire one TY that rocked back and forth.
I'm confused...but that's nothing new. Lmbo
Sir, you are wrong. You are NOT centering optically, but mechanically. There IS a difference.
I need to do more homework. Thanks, jim s.
