Trucker said:Mine has been absolutely flawless. I love it! The modular design is certainly different from the rifles I had been accustomed to, but the idea seems very utilitarian ... it works great for the purpose it was designed for. And that is the key .... I do not consider the AR-556 to be a target rifle. I suspect anyone expecting one hole groups at 200 yards will be disappointed in the AR-556. However, I imagine that working up a hand load for accuracy would yield some pretty good results. For my use the only possible objection I would have would be the fixed front sight. Seems that could be a problem if I were ever to want to mount a scope. But I can't be sure without investigating that issue.
I mounted a red dot optic and would highly recommend doing that. [My old eyes don't get it with the peep sights!] But if I were to want to use the AR for deer hunting [or long range targets] I'd want a scope on it. With the fixed front sight I think I'd either have to mount the scope really high or else have a fuzzy sight picture right where a really clear sight picture is critical. It's been years since I have used scopes or a rifle so I could be wrong. I do know I removed the iron sights on all the rifles I installed scopes on back when I was shooting .222's. 22-250's and 6mm's. But then I was low mounting the scope. On the AR I'd want the line of sight to be the same height as the iron sights so the the same M.P.B. calculations would apply. Perhaps some knowledgeable poster would comment on this issue for me?
I had same concern about front sight blurring a scope. I bought the Nikon P-series 2 piece mounts and a Nikon P-223 scope. These rings are high enough that the front sight does not create any problems with a clear scope picture. The rings being 2 piece off versatility in mounting the scope. Works great for me.
