Probably Norbar. They do the NP3 coating. I was told by Benelli that they were still going to fill the back orders but may have to make changes to make the ATF happy. They also said that they would adjust the pricing if they had to eliminate items such as the stock and tube. The stock could be changed, and I'm sure that Norbar would NP3 a tube, and that could be added, but the cost of doing that should be the amount of the price reduction. I also still have one on order. Not sure if I want it or not. I did pick up a standard black M4..... It's fun to shoot skeet with.
