    Somethings to consider:

    We are not limited to M855 ammunition.

    Increased cyclic rate only affects full auto reliability.

    Increased throw of BCG is not a problem when a properly matched buffer is used.

    Increased wear, but not a major factor if it increases usefulness for specific weapon. Don’t go short unless it enhances mission.

    The port pressures at the instant of bullet exit (uncorking) is only a factor if using a sound suppressor. If a sound suppressor is used care should taken to ensure proper one is selected, this should be based on full disclosure of intended platform use before purchase.

    I would not ever go shorter than a 10″ barrel.

    Mission specifics dictate weapon use, there are valid reasons for a 10″ barrel, just as there are for up to a 20″ barrel.
