finally got things all together guys! god am i so happy. hopefully next weekend i will have time to get her to the range. the upper was bought at my area gun shop, used, but never fired. Rock River Arms with Daniel Defense (or so i was told), freefloat system, and the Rock River Combat Riser. only thing i need to take care of is the gas key stakes. they are not that great to say the least. lower consists of M&P stripped lower, DD LPK, Magpul MOE stock and grip and trigger guard. oh and the best part...total price: $850 all said and done!
