Rifle Scopes MOA altering scope rings…..do they impair brightness? If not, any preferred brands/models/options to consider?

[want2learn]

My scope rail is integral with the receiver and i was hoping to extend distance capability.

I am considering purchasing MOA altering scope rings as I can’t change the rail on this rifle.

The 30mm Burris XTR signature rings in low should fit fine as they measure 0.41 inch from the rail to the bottom of the scope tube….this should still afford me enough space for a scope cover and they’re not too expensive.

Sometime in the past i seem to recall reading a post that suggested MOA altering scope rings might make the visual field darker….assuming one's eye remains properly in line with the optical axis, is this correct, does it make sense?

Also, any other brands, models or options i should consider? thank you

I have the Burris sigs in 30mm and they work well on my finicky 10/22 for the same reason. No darkness issues.

How would they make the visual field darker? All they would do is change the angle of the scope. Would putting a different MOA base on it do the same thing?

Classic case of analysis paralysis. I have a set of the Burris rings on an AR. No problems and they'll be my next purchase whenever I need new rings for something.

Whoever suggested that doesn't know what he's talking about. Rings that incline the front of the scope downwards do the same exact thing that inclined scope bases do. I've had inclined scope bases on several rifles over many years and have never have any negative effects on the image seen through the scope.

I run these rings on 4 different rifles; 22lr to 375 Snipetac. They work just fine.

perfect, thanks...just ordered some. appreciate the info. sounded weird but thought it best to check

I've been told the same thing.... but from a slightly different angle. That when you put too much moa in the mount then you are zeroing at the limits of the scope adjustment and it makes things darker,- maybe that's what you are talking about? I don't know if it really does or not. I've seen some ELR rigs with crazy amounts of moa built in (to the point that it looks like all they would see is the barrel) so it must not be an issue.

My atacr is bottomed out on elevation, it can be awkward to look through at times. But that only when the knob is all the way in one direction

If your getting any darkness do to shadowing that's saying your comb or cast adjustment (or both) are wrong.

I use a set of Sportmatch mounts that are adjustable for elevation on my cz452, and haven't had any issues.

SmartDonkey....i think you're absolutely correct, i didn't really understand what the purported etiology was

glad no one is experiencing such an issue....
