    I recently picked up a used Mini 14 that was sold to my LGS by a Police Department from their evidence room. The muzzle has a step cut in it. Did Ruger do this during the AWB to prevent threading?

    Looks like the standard Mini muzzle to me. The 10/22 gets the same treatment.

    All the new Mini 14's i've seen have the front sight mounted much farther forward than mine. Are they a reduced diameter beneath the FS?

    The Mini-14 that I purchased in the mid '80s (and still have) looks like that.

    IIRC, the one that I purchased in the late '70s did, also.

    Is the step a more standard diameter to make it easier for threading with standard dies?

    My 185-series (1987) Mini-14 is just like that.

    That's what my 188-series Ranch Rifle looked like, purchased 1989-1990.

    I haven't checked the diameter. Can it be threaded to 1/2-28?

    Mine bought about 1980 looked just like that. I don't own it now.
    I don't know about the diameter, but it always APPEARED to me that it could assist in properly lining up a threading die.

    I don't know your intentions or maybe you're just curious but I'll add this:
    Now that I actually OWN a suppressor, I realize that hand-threading your barrel is NOT the best course of action if your intentions are to install a suppressor. The threads must be aligned perfectly with the bore to prevent baffle strikes, which will destroy your high-dollar suppressor. AND the suppressor/mount bottoms out on a flat surface behind the threads which must also be perfect for proper alignment. This must be done in a lathe by someone who knows what he/she is doing.
    The last barrel I had threaded was done by YHM, the maker of my suppressor. All this may be useless info, just trying to help a guy out.:)

    Yeah, i would never hand thread for a can. Ultimately i'd like to chop the barrel and mount an integrally suppressed barrel but in the mean time i'd like to just have the option of mounting my can. However in the long run i'd likely save quite a bit just doing it all at once.
