Do all Adams Arms rifles come with VooDoo Innovations barrels? If so shouldn't it have the name on the barrel ?

I would say yes....But some one could have changed the barrel if it is used...Or someone could have picked up a upper and lower and built a clone. Does the upper and Bolt have the VooDoo logo on them?

I'd call them and ask as some Cos are buying barrels either unmarked or marked with their own logo. SWFA for instance uses Seekins bbls on their uppers, but they aren't marked Seekins like the barrels you buy from Seekins. Several other barrels I've purchased for various builds didn't even have the makers name, they simply had chamber and twist(ARP for instance).

Adams and VooDoo are the same company.
