If all goes right I should have my second AR platform rifle by the end of next week. That one will be a 7.62 caliber in full rifle length. My current one is an LMT MRP platform in 5.56 with a 16" barrel. Currently my LMT wears an ACOG TA11H. I'd love to run out and buy a Trijicon TR23-2G for the new one but funds aren't likely to allow for me to do that so I am looking at more affordable alternatives. One of them is to move the ACOG to the 30 cal and put an EOTECH 512 or 557 on the carbine. I am not sure though how the low power ACOG would work on a full length rifle. Does anyone have any experience with this particular ACOG on a .308? I'm gonna try it either way of course.
