At 20:46 he states for the most part the lower receiver's main changes are the markings as well as the laser engraving vs roll stamp.
At 28:00 he stated that the 6920 LE Carbine was using all US government parts, none subcontracted out......interesting.
At 34:15 is a statement about the quality of the rifle, which isn't the purpose of the video......which is where the parts are made.
Differences:
side vs bottom sling swivel
FSB markings
handguard epoxy
buttstock circle for manufacturer
barrel Chrome marking, date code, and manufacturer code
upper receiver markings
bolt carrier markings
bolt markings
extractor markings
