OP:
Like what I said at the Expanse thread at the Colt Industry forum, your serial number is very low 75K range compared to my early LE6920 roll marked M4 Carbine that I bought new in early 2012. My early production carbine have 100K serial number range, I'm not sure if there are any M4 Carbine marked lowers that are below 100K serial numbers. Also your mag catch is a one piece type (no rivet at the left side) and short selector lever which are the same as the Expanse lowers assembled in TX. I have an early Expanse model CE1000 with LE prefix I bought new in early 2016 with QR code above the selector, the markings are exactly the same as the LE6920 series carbines at that time period which have laser engraved QR code, Colt Defense, and serial numbers, the rest of the markings are roll marked. My lower have the typical Expanse low mass match type nickle finished hammer, one piece mag catch (no rivet), short selector lever with indicator line at right side, and unmarked standard carbine buffer. |
YMMV

Your lower is engraved, mine, and many others are not. I think that many of the complete lowers sold by Brownells are blems, and Colt dumped them to get rid of them. |
