| I'm interested in buying a Colt LE6921 with an M4 Carbine marked lower receiver. I've seen them available previously just marked Carbine and I want to avoid buying one of those. Is it possible to tell how the lower receiver will be marked based on the UPC number or does Colt just use whatever they have on hand at the time? The UPC number that seems to be available now is 098289020178. |
