I have a new Colt 6940 and would like to put on a drop in magpul MOE stock, However I do not know if I have a Commercial receiver extension tube or a Military receiver extension tube. My rifle is new does anyone know which one I should get for a COLT 6940?

My gut says Colt = Military...
Common sense isn't always right though....

Colt use 1.14" diameter mil-spec tubes.

They're right. MilSpec.
I'd spend a little more and get the CTR. You probably will later.
I'm just saying...
