I have a fairly standard scope on my .223 currently (3-9X40 I think) and although the power is OK, there is a very annoying "tunnel" effect where I have to do some moving repositioning to view the actual sight picture.

I can manage, but when I let my GF use my rifle she struggles with it.

I was thinking something like the Trijicon ACOG might be better, but I don't have the extra $1,200 to find out.

The red dot scopes would not suffer from the same problem, but they don't offer magnification.

I can't be the first person with this problem, any suggestions?

Evidently, you're not putting for head/face on the same place when yu shoulder the rifle...could be the scope is mounted too high for you to have good face contact with the butt stock.

Could alo be the scope is mounted a tad too far forward, and you've got to kind of crawl up to get that full field.

Get a Leupold.

Welcome to the forum milliamp. Some scopes do this. You might want to check out one of the Simmons AETEC scopes. Mine in 2.8 to 10 is absolutly excellent to look thru and you don't get the tunnel effect with it.

I've got a couple of the Weaver Classics one in 2 thru 10 an one in 3 by 9 and both of them do exactly what your talking about. I have a nice older Leapold fixed four power that does not.

Anyway again welcome to the forum, hope you enjoy it.

Position of the eye in relation to the scope is "key" here. You can't just "bolt it down and call it good". Start over is my advice. Take your time and do it right! Set the rifle up in a good rest and take the time to do it once! Unless abused by a drop or fall, you won't need to do it again.
