what do you mean "used as", do you mean "used with"a 2" tee being used as a regular vortex block
normally I wouldn't worry about bb capacity in a hopper fed vortex it should be like over 400 bbs either way so spilling out entire hopper's full would be out of my budget,
whatever man we got the sizes but what is the shape is it dwv like B, and C or is it sch40 like A
