its going on my rra carbine. its gonna be used/designed for cqb. i have a gg&g mad buis and wouldl ike to add an eotech. dont know which one yet, still reading on them. its gonna be 100 co witness. eotech will be used for under 50-60 yards like you stated. i got the mad buis for 100-200 yards. the acogs are great if your lifes on the line or want the most expensive scope monies can buy. for the 75% of us its a waste. why put a 900-1500 scope on a platform thats 800-900. makes no sense. plenty of scopes out there for a 1/3 of the monies that work great in competition. paying for the trijjicon name inho more than tech. with that said if you can afford it more power to ya:D
