M-14 Op-rod Identification

**318hyd** · March 04, 2012, 10:26

Need help Identifying M-14, M1a op-rods. What is the difference between
the government issue Op-rods and the aftermarket ones like Springfield Inc as compaired to The original Springfield Massachusetts ?

Thank you in advance!

On Springfield Armory, Inc. operating rods, look for either: 1) 7267064 on the first line and SA centered below it or together in one line 2) 7267064-2 on the first line and SA centered below it. The first example is the earlier of the two markings. Springfield Armory, Inc. operating rods with the early marking, no -2, will not have a notch under the handle like USGI operating rods. By no later than 1993, the notch under the handle was added to its operating rods, e.g., M1A-A1 serial number 0748XX. For clarity, U. S. government Springfield Armory operating rods are marked 7267064 SA all on one line and are machined with the notch under the handle but may or may not have the forward end vent hole.

The Springfield Inc op rod is in the middle. The USGI op rods are mounted in the rifles.

Is there any other physical differences that a person could spot say from a few feet away like on a table at a crowded Gun show?
You know so I wouldn't have squeeze between folks to examine an Op-rod that is not a GI contract made.

While on topic I have always wondered about the origin of the op rod that Im using in my match M1A, it has the PN# 7267064 and underneath 66118?

Thank you all for your inputs and pictures.

The 7267064 with 66118 underneath is a Winchester Op-rod
