    O3A3 barrels

    Probably elementary to most forum members here but how does one tell the difference between an 03A3 barrel and a regular barrel for an O3?

    I got three out of that auction and one has buggered threads. Use for a picket pin.

    The others appear decent and usable. I made the quantum jump that they are A3s as almost all the parts with them are Rem. O3s.

    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.  I will accept PayPal, Zelle, MO and good old checks (and cash if you want to stop by for a tour!).  CLICK BANNER to send me a PM for International pricing and shipping. Manufacturer of various vintage rifle scopes for the 1903 such as our M73G4 (reproduction of the Weaver 330C) and Malcolm 8X Gen II (Unertl reproduction). Several of our scopes are used in the CMP Vintage Sniper competition on top of 1903 rifles. Brian Dick ...

    '03 has a uniform diameter section for rear sight base.

    '03-A3 does not as the rear sight is on the receiver.

    Those visible in the photo are '03-A3.

    M1903, barrel diameter at shoulder: ~ 1.145"

    M1903A3 barrel diameter at shoulder: ~1.200

    M1903, front sight attachment: spline milled integral with barrel. Notch in spling at rear for fixed base pin.

    M1903A3 front sight attachment: three milling cuts form a seat for removeable .1" square key. Key has notch in middle for 03A3 front sight base pin.

    If the M1903 barrel has ever had a rear sight fixed base attached to it, it will have a longitudinal slot at the shoulder, in the 10:00 or 2:00 position; and a transverse slot at the 6:00 position in approx 2.9" forward of the shoulder.

    Resp'y,
    Bob S.
