I've had my MR556A1 for about three months and while I have an Aimpoint for it I really like using iron sights. The Troy sights that come on it are fine but I wanted to ask if anyone is using that 2mm quick change rear sight (and its matching flip-up front sight) that I've seen on HK's web store. If so, what is the best application for this type of sight? Is it the same as any other, just easier to adjust without tools? I also like that the corresponding front sight doesn't take up rail space.
Thanks for any advice.
