just like title says what would you guys recommend for close up and far out work. trying to be able to take the 6.8 out to atleast 700 yards and use it in as a close quarters weapon. i love the acog for my 5.56 ...but just curious to others experiences. i got about 1500 to spend. i have been looking at the nightforce 2-10 w/ a zero stop and mil adjustments. any other suggestions ?? any help would be appreciated
