Are there any Sprinfield's stamped "M14" that are NOT NFA rifles?

There is at least one probably a couple more.  Years ago, a case went to the SCOTUS regarding a semi-auto U.S.G.I. M14. IIRC, back in the 60's some G.I match rifles while made from M14 receivers, were permanently converted to semi-auto only from the factory. Some eventually made it into civilian hands. The ATF set about seizing these un-registered "machineguns" under the "once a machinegun, always a machinegun" rule. The ATF lost the case.
So, there is at least one and perhaps a few others that were covered by this case.

My recollection is there were no more than a dozen of these "factory" semi-only M14 Rifles and none of them were Springfield Armory (not Inc., the real armory).

If you're offered one be verrrrrrry careful.

I have a pre-ban M1A thats didnt get much of the left leg of the "A" when it was stamped.  Does that count?

There are a "few" out there that have been assembled from rewelded receivers.  Some are legal, some are not.

Try over at www.battlerifles.com.  There are some really knowledgeable M1A guys over there too.

Here's a list of U.S. commercial M14 type rifle manufacturers and their model numbers as best as I have been able to gather.  If someone other than the manufacturer made the receiver they are identified as well.  For example, Armscorp makes receivers for Fulton Armory.  The hyphens in the model numbers are as they appear on the actual receivers.  From m14.freeservers.com

There were some few US Military M14's, that weren't full auto, can't remember much of the details. Go over to Battle Rifles, and perhaps you may find more.

The USGI M14 M (Modified) was a rack grade M14 that had the selector components welded so that a selector switch could not be added.  This is a separate animal from the USGI M14 NM (National Match).
