Yeah, when my upper gets here from Palmetto, I will have about $500 into this rifle and it will be pretty much as close to mil spec as you can legally get without going NFA... 4150 CL HPT/MPI barrel, C158 HPT/MPI bolt, and so forth. When you can build a top quality AR for that kind of money, you know the market is about as saturated as it can get. I have a hard time seeing how there was any profit margin at all on some of the stuff I bought on sale over the past year. Take advantage while you can. Someday we will fondly remember the days of $500 mil spec ARs, just like guys pine for the cheap mil surps and imports from days past.
