ok So im mounting my 4x16 scope to my RRA Elite Operator
Im using the RRA one piece mount

both scopes ive mounted had the same issue so it seems its not the scope possibly

what i am seeing as i look thru the scope is that usually the top crosshair is "split"

sometimes its the other crosshairs but mostly the top

and its not everytime i look thru the scope

could my front site be possibly interfering w/ the scope

I was told that it shouldnt affect the vision thru the scope
funny thing is that it still does it off the gun lol

Ive even tried to move the scope back and forth on the mount and it seems to not improve anything

could it be that i hv the scope set up wrong or is the site in the way?

I'm not quite understanding. What do you mean by *top crosshair* and *other crosshairs*?

How many cross hairs are in those scopes of yours?

To rule out the front sight possibly being the *split crosshairs issue*, pull the scope off the rifle, look through it and see if the problem is still there or went away.

OR a better option, take a Dremel with a cut off disc or a hacksaw and whack most of the front sight off. Take a file to it and do some further shaping and get the sharp edges off. Touch it up with flat black paint. Don't need most of the dang thing anyways.

Another thing to consider is the distance to the target you're viewing when you see the problem image.

If you see that image when indoors you are probably looking at something far closer than you could hope to use that scope for. Go outside and look at something 50 yards away on 4x. Such a shadow image from the front sight at close range should disappear/fade at a functional (40-50 yards) distance and farther.

Have you set the diopter (focus) adjustment correctly?
I've seen that "doubled crosshair" when it was misadjusted.

Just an idea.
 
You either need to focus the crosshairs better or you have a vision problem. Try focusing the crosshairs first, it doesn't cost anything but time. Then time for an ophthalmologist.

There is one other possibility.
The top of the vertical crosshair may be displaced from where the rest of the crosshairs are. That would be a scope problem.

1) With the scope off the rifle, set your diopter (eyepiece) by looking through the scope at a light colored blank wall and adjusting the eye piece all the way out and then slowly turning it back in until the cross hairs appear sharp to your eye...If you wear glasses, keep them on...

2) Place the scope against a mirror, on the lowest power setting, and adjust your elevation and windage knobs until you only see one set of cross hairs,, this will insure that your cross hairs are centered...

3) Mount your scope on the rifle, making sure the horizontal cross hairs are level with the rifle (use a small bubble level on the rifle, then the scope).

4 Looking at a distant object through the scope, preferably at an object of known distance, and adjust your objective bell to the point that as you shift your eye position while looking through the scope, the cross hairs do not shift on the object you are looking at...

If after all this, you are still seeing double cross hair lines, spend the money to see an opthomologist for an eye exam..or your eyeglasses may be refracting the cross hairs..
 
i do hv glasses not bifocals......i was wondering about that
Is diopter the same thing as the eye relief?

Its funny my other scopes work fine or i see thru them fine

maybe the scope is adjusted wrong????

I know this doesnt hv to do w/ the eye relief but i hv the scope set on infinity

Eye relief is moving the scope forward/back until the image is where your eye ends up with normal cheek weld.

Diopter is making the image "in-focus" for your particular eyesight. You do that by screwing the ocular lens in or out.

I usually adjust it by watching the crosshairs, and if it's out either way, the crosshairs start to "double" like you're describing.

Okay, that shouldn't have anythoing to do with getting the crosshairs looking crisp. That just moves the focal point of the distant target to fall on the same plane as the crosshairs.

I think that'll fix the problem.
That's the first thing you need to do with a new scope, and do it with your glasses on like OT said.

Well there's your problem. Most all scopes, unless special ordered, are manufactured for the right eye. You need to get a scope made for a left eye.

When you order it, be sure and tell them your left eye is kind of funny and they will build you a funny type scope to match the eye. It's amazing the things they can do these days.
 
I watched last comic standing once. One of the women had kind of a funny nose. Well not so much funny. More like bent. Crooked, ya know? Hard to explain. Did you see it?
