What I'm asking is , if it's not all CC parts , would it make much difference , in a resale situation, if it were a Colt USA lower or a LMT lower. Would it be easier to sell if the IUR had a colt us lower instead of a LMT ,etc?It won't make any difference, unless you want to keep it all CC, but thats up to you. Any quality lower will work just fine on the IUR upper. I'm using a Bushmaster lower on mine, and it just fine, thank you.
