    I have seen mixed responses from across the web about the compatibility of the M4 S-System's outer barrels with other M4 outers. I have a JG S System and I want to have a shorter cqb style barrel to go along with my shortened inner barrel.

    And just so you all know I searched through quite a few forums and Google for this information.

    Yessir. Another fruitless day of meandering through various forums looking for the answer.

    The S-System has a special barrel. So no you can't just throw a new barrel on. If you are looking for a shorter barrel you will have to try and source a PDI short s-system barrel. If you can't source one of those then you can try to cut it down and rethread it. Don't know how will the cheapy barrel will hold up to that though.

    Most likely around a 10.5 inch barrel from what it looks like.

    Okay thanks. You know what the exact differences between normal and S System barrels are?
