It's a good choice. Have you considered the flat-top version? You can put optics on a rail much easier than on the carry handle. A free float handguard with rails is also handy, as is a fold-down front sight. Of course, all of this adds cost, but also adds flexibility.
I was actually thinking of the flat top version. Then I could get a holographic sight along with the fold down one you mention...I think. How does that sound? Thanks.
