    The OP needs to replace the barrel with another barrel made at the factory to his desired length.

    He can sell off the 6920 barrel and get a DD 12.5" and will maintain factory originality. It is also easier to do if you have the right tools.
    The people that do my AR work don't pay dues to the UAW. But their work is perfect.

    The OP doesn't "need" to do anything other than what he wants to do.

    There's a lot of guys that do quality barrel work, including chopping and threading them.

    16" M4 barrels are already "wrong", and 6920s are cheap enough now that they make great SBRs. I cant see buying one without replacing or chopping the barrel.

    Most places like ADCO do that already, Ill take threads cut by a guy running a machine over a mass producing factory job anyday.
