I just bought me a DTI mid length AR15 with all Magpul furniture. I got some MBUS back up iron sights and an Eotech optic and I feel ready to go. This is going to be my first time shooting this platform since 1972 when I was in the Army. I was pretty good then with just iron sights. Having this new (top of the line) red dot is exciting. Hope to go out and zero it this weekend. This is my first rifle ever... Now to find a good .308 long range rifle so I can reach out and touch someone past 350 yds....
