I picked up an M1a last week.  I am wondering which model I have.  At first I thought I had a National Match but now I am not so sure.  Here are the details.

Ser.# 129XXX

barrel-Stainless medium weight? and marked  National Match .308 SS

Stock-USGI w/rubber buttpad and painted black.

Front sight- marked NM

Flash hider-reamed out

Gas system is unitized.

This does not match the current National Match specs but I can't find an older catalog to see exactly which model this is.  

Any help would be appreciated.  Thanks!

I would call Customer Service at Springfield Armory, Inc. and give them the serial number.  They can tell you what model it was built as in the factory.  It sounds like some parts have been changed.  Is the rear sight hooded?

If it's not bedded, it's not.

Different...nope it is not hooded, that is what has me confused.

I will call them tomorrow

Another question, can you tell me the part number for USGI Springfield Armory parts?   I used to have that info but it was on an old computer so it's gone.  The Oprod and the trigger group might be USGI.

You may have the "loaded" model. It has many attributes of the National Match. I bought a "NM" and had a hard time justifying spending more over the "loaded" model.

Download a freebie copy of M14 Rifle History and Development at www.m14.ca  That .pdf file will give you what you need to identify M14 parts.

I only broke it down once so far.  Of the 5 M1a's that I have owned, none have been so hard to break down.  I had to pull on the trigger guard and the mag well area to get the triger group out.  To be honest I was more interested in USGI parts count.than if it was bedded  but I did not notice any thing similar to what I have in my bedded Bolt guns.
