I found a 15.5” AR-10 gas tube on Wilson Combat’s site and ordered it.

It's legit - I still have a spare from them in the packaging.  It's real - you did well.  I honestly forgot about them, as a solution, because they just recently started doing that.

Update: installed Primary Arms 5.4oz Buffer weight, Springco Orange Spring and Wilson Combat’s 15.5” AR10 gas tube. Gun runs flawlessly on 50 gr Hornady Superformances, 4100 fps. 
I will say gas key on BCG and gas tube port are a “snug fit” takes more force than usual to get the BCG out of the upper when taking apart but it honestly doesnt concern me as it doesnt feel like its enough resistance to hinder performance. 
My last question for you fine gentleman would be, down the road when i go experimenting with lighter bullets and more fps, if i run into a gas problem and need to drill out the gas port on the barrel, with this build, what size gas port is recommended?

thanks again to everyone who stuck this out with me.

What size is the gas port right now?  It's obviously working, so don't mess with it. 

Down the road, you won't have to change the gas port diameter for a load - if you go to even lighter bullets, the charge weight is different, and it doesn't matter anyway, since you now have a balanced gas system and recoil system.  Getting those two working together is what gives you the heart of your reliability.  Loads can change now, you can even shoot heavies - won't matter.  The two systems are working together, as designed.  :thumbup:

What magazine is working for you? And how many do you load?
