First assembly, tried to keep the cost down. R Guns lower and a DSArms ZM4 A3 upper. Feel free to ask on any of the other parts, pretty simple. Only 200 or so rounds through it so far but no issues with steel case and shot tight groups. Good enough for me to have fun plinking around with 
sorry for the cell phone pic!
Welcome to the forum buddy. Lots of good info here.
Read the stickies and put on your thick skin. Dont be offended by suggestions.
I would suggest you sell that upper while you have a low round count through it and use the money towards a BCM.
