    Not trying to be facetious, really just trying to help, but they're available from Chambers/Gunspares (though doesn't confirm size):

    I think you will find the thread size is 3mm. and the length is approx. 15mm.

    I have a box of similar screws, ex computers, so give me your address by PM, and I will put one in the post. It may not be Hex Head as per the original, but will do the job.
    I have one of the silencer adaptors in front of me right now.
