Matrix upper, lower, handguard and lower build kit, Magpul MOE fixed Carbine stock & K2 grip, Toolcraft BCG, Larue MBT trigger, Armalite buffer tube setup and Bushnell 3x12 scope. 98Z5V did a burnt bronze Cerakote job on it for me. I haven't had much trigger time with it yet but the 100 yard groups I was getting off of a crappy azzed rest were pretty good. I am trying to find some time to get back out to the range with the bipod on it and really wring it out.
