    Odd Screw in Rear Sight?

    Hey all,

    I don't mean to bloat the forum, but I'm not sure where else to ask technical questions. I'm still learning about M1icon rifles so I am bringing all my questions here to bother the experts.

    I'm looking at a particular rifle that has an amalgam of parts assembled into the rear sight: a Springfield Windage knob, a Winchester Lockbar, and a Winchester Elevation Knob. The screw holding the Elevation knob is what is standing out as I have never seen that before. It doesn't look like a screw on the T105 sights, just a regular old screw. Has anyone seen that before?



    Finally figured out how properly upload photographs. Thank you Bob for the walkthrough!

    Respectfully,
    - Michael

    A Collector's View - The SMLE Short Magazine Lee Enfield 1903-1989. It is 300 8.5x11 inch pages with 1,000+ photo’s, most in color, and each book is serial-numbered.  Covering the SMLE from 1903 to the end of production in India in 1989 it looks at how each model differs and manufacturer differences from a collecting point of view along with the major accessories that could be attached to the rifle. For the record this is not a moneymaker, I hope just to break even, eventually, at $80/book plus shipping.  In the USA shipping is $5.00 for media mail.

    The rifle is admittedly not mine, I saw it as a listing online. It is a 6 digit Winchester with Winchester parts (although not contemporary to the receiver).

    It is a peculiar piece that stuck out to me. I doubt any armorer would jerry-rig a design like that at an arsenal.

    No, correct screws are even available to the layman...

    elevation knob screw

    It is not just a small machine screw but manufactured to fit the pinion and hold the elevation knob tight

    Well, the outside screw is a screw...and it's wrong. The outside is holding things tight I guess.

    The trouble is if someone has forced in a screw with the wrong thread they may have messed up the thread in the part that the screw fits into, the pinion.
