Great scope, clear optics, well designed reticle, can't ask much more - Trijicon TA11F-A ACOG 3.5x35 Rifle Scope - Chevron BAC .223 Flattop Reticle with Flat Top Adapter

This is an excellent scope if you need a bit more eye relief than the TA31.
The TA31 requires you to get quite close to it, where the TA11 is much more generous. Only drawbacks are size and weight.
But if you want to be able to mount up more quickly and get a fast sight picture, the TA11 is the winner.

Also on higher recoiling guns, the TA11 will have much less chance of 'scope eye'.
Pros: Awesome eye relief, clear glass, easy reticle to work with, bright illumination
Cons: Heavier and bigger than TA31, field of view narower than TA31 w less magnification
