It makes no difference. Parts are the same. Number of commercial guns Colt sells is tiny compared to FMS and USG sales. There is a lot of material for you to research on this site.You have the Cr6920 or LE6920?
Parts come in the same boxes prepared to the same specifications some are just taken on the commercial side. Difference is on the commercial, the documentation that is required to follow everything being delivered against a Prime Contract Material Inspection and Receiving Report (MIRR) or as some remember a DD250 is not.I took a look at your article it makes sense now so they all go through the same quality control inspections and are all held to same standard to meet colts quality
I have no idea where to begin to take this one apart.... Wrong on so many levels.Things have changed in the AR business. When the 6920 was introduced in the late 90's there was an assault weapons ban in place and very few manufacturers. This has changed substantially. There are now very large manufacturers which support both the Government and the Civilian population. Colt has moved to leverage some of these resources with their rifles. In the late 90's Colt owned the TDP. This changed in 2009 when the Government purchased these rights. This allowed the Government to source parts from other vendors. Colt has taken advantage of the shared resources to source parts which are expensive to build in house. The Union has fought this but apparently has only been partly successful. Rasco has a cage code. AO Precision has a cage code. The parts have changed over the years. Only Colt knows how each part is made. Company's either adapt or die. Money always matters. If you want a gun with the old markings and manufactured by Colt there are usually several on Gunbroker. If the markings are less important and if you don't mind that some parts may not be manufactured by Colt then a new 6920 is for you. If you would have purchased a new 6920 in the summer of 2008 the rifle would not have been manufactured to the TDP. The hammer/trigger pins were larger than standard along with other changes.
