Trijicon Acog for Colt LE6920 help??

I am interested in an ACOG for a Colt LE6920. Any help or info would be appreciated.
Looking at TA 31, TA31RCO-M4CP and TA 11

Will be using for combination shooting steel plates 8" diameter at varying distances to maintain proficiency as well as coyote hunting.

Does anyone have experience with these specifically?? If so, do you recommend the flat top mount or mount on the carry handle?

Also, how does the front sight interfere if used with a flat top mount based on experience.

I am looking for specific info not general opinions please.

If you hit the Search function and just put in “ACOG,” you’ll come up with a multitude of threads.

In the meantime, DON’T do a carry handle mount if you have a removable carry handle. For one, most of the flat-top-mount designs are scaled for just that; receiver mount. Also, you’ll have a ganked-up stock weld if you go carry handle.

The FSB will appear blurry in the bottom of the FOV, but will be transparent and not interfere with shooting.
