While doing some research, I noticed two interesting things on this section of the Colt 2014 product fold-out.
1. The LE6920AE shows the ambidextrous lower receiver that we currently see on the M5 Tactical Carbine.
2. The LE6920SOCOM is listed with the Troy rail system. Although we have known for years that Colt made the 2013 model SOCOM with the Troy rail, this is the first time I noticed it formally acknowledged.
