Just checked them out. Do they actually put the Colt branding on the lowers and just don't show it on the site? Otherwise kinda meh. What's the point if the markings aren't complete anyway? If anything, I'd rather get a blank lower in the white, have it fully engraved and then send it off for anodizing. Would be nice if they offered a service for gray anodizing. Not many places to go for that these days it seems.
But I used to know an engraving shop that would do full Colt markings on a blank lower for you. US Property or Commercial marked. Whatever you wanted. Engraved vs. properly roll marked I suppose (INTLMILCO seems to actually roll mark theirs). But having the markings be complete counts more than having them actually roll stamped to me I guess. But it was a small one-man operation and he pretty much did it to order so I guess he stayed under Colt's radar and avoided any trouble from using their trademark.
