    I took the lower apart from the upper to install my DD RIS II, and now the magazines won't lock in place.

    I'm guessing it might be the wiring getting in the way.

    But I have no idea.

    It's gotten harder to bolt the receivers together.

    I just don't know what could be the problem.
