With the exception of the fact that I'm not a big fan of vertical foregrips (I like afg's more), not too shabby. I'm of the opinion that it needs a sling still, and I think I like the tube style reddots better. Since I'm not using mine as a primary defensive weapon at this time, I don't see the need for a light on mine, but I have one available if SHTF tomorrow. Thats the great thing about an easily modified weapon, your rifle can be built to your liking, and mine to mine. Looks good though, how's it shoot?
I would get rid of the Surefire set up and get one of these Elzetta Tactical LED Flashlights, Weapon Mounts, USA Made . I have the 2 cell with strike bezel and the high /strobe mode and their Zorm mount and it has been great! Virtually indestructible and bright!
From a "cool" perspective, it looks pretty slick. If you don't feel complete yet, ditch the handle and convert to a flat top. Move your EOTech back move your light to the side and mount a mean looking bayonet under it! Of course you can go too far, but it depends on what you want out of it, it's yours not ours! Congrats! Have you checked out AR-15 Builder - Build and Customize your own AR15 | Brownells ? It's a site that allows you to make your own with a ton of add ons, and see what it would look like.
