3x magnifier

[Hoss0432]

I just put a 3x magnifier on rifle and when I look through it the dot seem to be in the upper portion of of the field of view. When it's flipped to the side the dot is center of red dot. I only have bore sited it. Is this normal with them or is it just me?

You can buy magnifiers that are set up for absolute co witness and lower 1/3 co witness. You probably have the wrong mount. It sound like you have an absolute and need a lower 1/3. That would raise your magnifier up higher.

Alternately, you may just need to adjust the windage/elevation of your magnifier to center the dot in the field of view.

I got it second hand no paper work. They look inline and didn't see any adjustment but thanks for the input. It is a utg do that might have a lot to do with it

Here's a pic

You may be stuck with it the way it is. You may be able to adjust the mount of your magnifier to help it line up better, or there may be not much you can do. It won't affect the impact point of the bullet either way.

That is as close as my Aimpoint T1 with LT mount and Aimpoint Magnifier with LT mount. I would run it as is. I've never had any problems.

Thanks for the help. I am shooting in an action rifle match Saturday so I will give it a shot. I will let y'all know how it goes. Once again thanks

Is it the picture or does it look like the magnifier is slanting down toward the red dot? A solid mount is key to alignment for optics.

After a little sighting in I had no problem ringing the steal at 200 meters. Only down side is the dot is as big as the target so all I could do was cover it up and squeeze the trigger. Bottom line it worked and I liked it. It was a little bulky with it folded to the side but in time I will get used to it. I bet if I had a higher quality red dot with a smaller dot it would be even better. My dot is 4 moa x3 = 12moa at 100 yards so at 200 meters (218yards or so) it was 24moa. I think it's some thing like that if not iam sure some one can correct me.

The size of your dot in MOA isn't (or at least shouldn't be) dependent upon magnification - a 4 MOA dot should be ~4" at 100m and ~8" at 200m, regardless of magnification.

Exactly. You are magnifying the dot, but you are also magnifying the target at the same rate, so the dot size to target size ratio is the same.

That's why I like this forum I learn so much. Thanks to all who was willing to educate this knuckle head.

 

[cyphertext]

It isn't that you are a knucklehead, it is just a little different. On most scopes, when you kick up the magnification, the reticle stays the same size, while the target is magnified. You are probably more accustomed to scopes of this nature.

If you could put the magnifier in front of the red dot instead of behind it, then the dot would appear to remain the same size while the target size increased. I doubt you can do this though due to eye relief needed for the magnifier.

Check out this video for an explanation... doesn't go into great depth, but will help you picture it.

EoTech holographic sight dot perception remains 1MOA when using a 3X magnifier because the dot is really 1/3 MOA. The human eye is diffraction limited and perceives the non-magnified EoTech 1/3 MOA dot as 1MOA.

The fun aspects of optics.

As others have said the dot itself is magnified but so is the target therefore the 4 MOA remains 4 MOA. I have been thinking about adding a magnifier to my XPS EOTech2-0. Are they an easy mount / dismount when not shooting at long range? I don't want an extra piece hanging off my rifle when I don't want need it. I assume since the magnifiers have no reticle you can slam them on and need to adjust nothing. Is this true?

But the outer ring is magnified... Haven't played with an EoTech, so I don't have my head wrapped around that yet...

Yes you can remove the magnifier for the short range and slap it back on with out loosening zero. It has no adjustments as long as it lines up your good

You can get a quick attach mount or there is the one which will mount direct and has a large "screw" that holds it in tight on the rail. Trouble is you want to match the two together when you buy them to get the heights the same for both. You ALSO want a magnifier that has side to side and up and down adjustment so you can center your dot. Also get a magnifier that comes with an "add-on" adjustment plate that can be added between your sight and mount if need be. Once adjusted, the magnifier will/does stay in focus even taking it on and off.

I have EOTech sights and magnifiers with quick attach mounts and ones with-out. The quick attach sit just a bit higher on the rail and "might" need a slight adjustment (the sight it's self) when taking on and off.

I like both type mounts "for what they're intended for". If I had to pick only one style I'd take the solid mount. A bit "cheaper" with-out the QA mount and no worry about adjusting.
