Rifle Scopes Help with Burris MTAC 1.5-6x

[nheiny13]

I recently bought a Burris MTAC 1.5-6x and enjoyed it. I sent it in to have the shorter turrets installed on it and when I got it back the turrets were really difficult to turn and there were a couple specs of dust/dirt inside of it. I sent it back in to have this fixed. Well, when it was returned the dust was gone and the turrets turned easily but I noticed a new problem. When I turned the power to around 2.25 and down, the "picture" of what I was viewing shrunk, ALOT. Now I know, when looking through a scope, there will always be a "black ring" around your sight picture, since the "black ring" is the actual scope itself. When I turned the scope below 2.25x this "black ring" got thicker and the sight picture got much smaller. It looks like a diaphragm appearing and makes the sight picture much smaller. Also the Field of View stayed the same from 2.25x - 1.5x. Normally this should not be since FOV increases with less power.

Now I don't remember noticing this before I sent it in to Burris the second time. I sent it back to them a third time to fix this problem and they told me nothing was wrong with it and this model is designed to have the same FOV from around 2.25x-1.5x This just does not seem right to me.

Can all of you owners MTAC 1.5-6x owners verify what your scope does and tell me if my scope is faulty and Burris is wrong (Hoping so because sight picture at 1.5x is AWFUL now)

So...
I don't think what your describing indicates a problem with your scope or more specifically any inherent trait of Burris' Mtac line. I will try to itemize this for you, maybe it will clear a few things up:

1) You should not see a black ring when your eye is properly positioned behind any scope.

2) Your proper eye position is sensitive to 3 directions: vertical alignment, horizontal alignment, and relief (distance)

3) Improper placement or mounting of an optic can negatively effect its image (if you are hunching, contorting or straining to reach). This includes mounting an optic that is too high above or below the line of sight you can obtain from a comfortable cheekweld.

4) Your eye relief can change in tandem with changes in magnification

5)Your field of fiew will increase as you lower your magnification

What could be happening... If you have mounted your optic at a height or distance where you are still seeing a slight black ring at your best picture, your problems will be magnified (no pun intended) as you slide through different settings). This may also cause what appears to you a lack of increase in FOV as you may be missing part of the picture.

Try removing the optic and look straight through it at different settings; you will have to hold it at slightly different distances based upon the magnification. Re mount the optic to your natural position behind the rifle based upon your needs for proper cheeck weld, alignment and relief (remember to to pick a position that is comfortable throughout the magnification range, you should adjust up and down before deciding on a final spot).
You can check the forums here for much more detailed info on mounting, theres alot of it.

Hopes this helps. I apologize if this is more basic information than you were looking for and I'm not drawing any conclusions about your experience. I think sometimes we all encounter issues that may look over some of the basics and when I heard you mention that scopes were supposed to have a black ring... I figured I would start there..
