I am in the planning stages of my SBR build and am trying to figure out my upper. I know what I want, but I dont know if it will work. I tried to do some searching, but I couldnt find anything definitive.
What I want is an 11.5" upper with an 11" Troy TRX Extreme tube on it with a Battle Comp 1.0. Does this combo fit together or would I have to go with a 9" tube? I am 99% sure I will never put a suppressor on the gun so I am not worried about clearance behind the BC1.0.
