I bought one 2 weeks ago for my M4. It seems to be well built and simple to mount dial in and use. I am going to nuy another one this weekend for my G36C. Very good buy in my opinion!

this acog is definitely a nice rds. kyle has one for his cqb aug. just be sure not to overtighten the adjustment caps; the red rubber o-rings could easily be damaged.
