the titanium upper I ordered was not available due to circumstances beyond AA's control so they offered me the tungsten colored as a consolation. Hell, it was an upgrade this thing is dead sexy! it functions flawlessly I've been offered $500.00 for just the upper. it is set up minimalistic flip-up sights and a small hand stop on the bottom. she holds a 1/2" group at 75 yds consistently. with the kac shockwave pistol brace. great product!
