I started a thread some time back when I started asking questions about the variants of .308 AR's. This is my first attempt at putting together a "big brother" AR and I can say I have learned quite a bit. Over all I am pretty happy with this. I spent a little more money than I planed on but I think it was well spent. My biggest gripe with it so far is just its weight. She is a tank. With a empty magazine and the bi-pod she clocks in at 12.5 lbs With a optic and loaded mag its gonna be 16 pounds! And this is a relatively light 16" barrel. Cant imagine what it it would weigh with a 22" bull barrel! I am hoping this weekend I'll get a chance to see if it goes bang. It is mostly Aero Areo 16" 1/10 Stainless bead blasted barrel Fortis Stainless gas bock. Spikes nitrided gas tube AAC comp/flash hider Aero enhanced upper and keymod rail Aero M5 lower GGG folding sights Magpul UBR stock CMC 3.5lb flat trigger B.A.D.-A.S.S. Ambi saftey AXTS/Raptor ambi charging handle Aero/Fail Zero BGC Currently has a Atlas bipod So know I want to build another one. I suppose that is the way it always works. You learn something and then you want to do the next thing. I think I might try and build a much lighter version of this same rifle. Find a pencil barrel and put on a Magpul ACS-L See if I can get down in the 7-8 pound range. Anyway She is not a Si-Defense or one of the Rainer branded Mega rifles but as she sits with the used UBR stock I am into it about $1350 without sights or a magazine. Right at about half what one of those "fancy" rifles would cost. If it will put 5 rounds in a 2" circle at 100 yards I am gonna call it a win.
