I have some money for a scope for my Colt AR. It has a fixed carry handle. I would like to buy a scope and mount for it. It is accurate but I don't see as well as I did when I was young. I hand load the sierrra 77 grain moly coated round an it shoots very well. I can't see out to the range I would like to shoot. What can I get for a few hundred that would also let me use the iron sites as well. Thanks, John Mason MSG USA (retired and getting old)
