    Consider that many people have complete DD lower equipped weapons. Is this something like a poorly staked BCG that should be replaced on a duty/hard use weapon, or not so much?

    I don't see how an aluminum endplate is as good nor do I think that the weight savings is significant.
    I agree with you, was just stating that receiver ext is actually held in place by a properly tightened castle nut. The plate does little to nothing for holding the RE in place. It does help hold a castle but by staking, but is it worth taking a factory built rifle apart from a quality manufacturer such as DD like the OP is asking about to replace it with a steel one?
    Does everyone need to take apart their newer KAC SR15 apart to replace the castle but because it isn't staked, but is torqued correctly to prevent slippage?

    I doubt I'd go to the trouble of replacing an Aluminun plate.

    If it's already there, don't worry about it. Search here and the web and see how many broken DD end plates and receiver extensions you find. My prediction is zilch.

    Isn't the Endplate used in the DD torture test "2" the newer Aluminum QD endplate that is spoken of in the OP? I didn't see it causing anymore failure than the steel one from the DD torture test 1

    There are no mechanical concerns with an aluminum end plate as it is not loaded when installed properly.



    If a sling socket is installed in the end plate then it is loaded and the plate would need to be looked at differently. Increasing the thickness as DD and others have done seems to be sufficient here.

    Nothing wrong with an aluminum end plate if its just an endplate, however if its also a QD Mount I wouldn't trust it. I'd replace it with a steel mount since your QD attachments are made of steel which will wear out an aluminium Mount.

    From what I've seen they all have a steel socket still.
