I have the same rifle, Very reliable and a good shooter. As has been said, you should invest in some sights in case the Eotech fails. In my case, I bought flip ups to become efficient with before I buy optics, and I honestly may not ever get optics.I had wanted one for a while, but I decided it was time to get my "homeland defense rifle" while the gettin was good. I'm happy with the Armalite - the Eotech is nice but not as great as I thought. My eyesight is not perfect so the 65 moa ring is a little fuzzy, but the center dot is fine and as long as it is turned down, it does the job.
