It doesn't mention a weight but for what its worth it is going to be heavy. I have found heavier barrels can get nose heavy on the Thordsen. At 16" that might not be an issue for you.
With that said I have a .750 Lothar with matched BCG on one of mine, they make some very nice stuff.
Have a few ARs was thinking about bull barrel to change things up. Seems like a great price for a Lothar.
