I've seen many Red Dots and Holosights, and even a couple of long eye relief scopes mounted on carry handle rifles like the one in Anna's picture. This set up works very well.
I prefer the ACOG mounted on the handle, but that's personal preference for the ACOG, not criticism of the forward mounting system.
For those who have fought for it, freedom has a taste the protected will never know!
Or at least they did before political correctness
