Ok so I picked up these parts and am waiting 10 days for my lower: Stag Lower Stag Upper with Front iron sights, and rail Model 5H DPMS Panther Arms Lower reciever parts kit Mil-Spec Stock Prince 50 Forgot the 10 Round Mag brand. So, what do you guys think, picked it up for about 950 out the door. Also, what tips do you guys have for me in the build? Optics Choices? Rear back up iron sights.... ? I was thinking a rear backup might be a nice idea in addition to the red dot.... Or someone suggested a carry handle with a dot sight mounted to it.
