The only reason a stock Colt M4 costs $500 is because the military signs contracts for tens of thousands of them and that drives the price down significantly. When I was in, the Army was paying more money for a tracked vehicle driver's helmet than they were an M9 pistol. I have my doubts as to whether a commercially available Colt rifle is held to the same QC and testing standards as the rifles the military buys and the commercial versions are a lot more than $500.
Our SF teams don't take new out of the box rifles and head into operations with them either. They have fully staffed professional gunsmiths who work those rifles over to their specifications before the tip of the spear guys use them.
I'm a huge fan of the AR15/M16 platform, always have been. There are different levels of quality control and acceptable tolerance deviations in the industry. One particular manufacturer of parts may sell to 20 different companies but that does not mean that all of the parts are equal. Tighter specs and more in depth testing can play a pretty big part in which company gets which parts from that manufacturer. Some manufacturers have looser requirements than others. If I were building a plinking rifle I'd have no issue simply searching out the most affordable parts I could find. When I needed a rifle to work with I consulted those in the industry I trust and went with what I believed would stand up to the hard use my rifle sees. Could any rifle out there stand up? Maybe. Ain't betting my life on maybe.
