I was wondering if Norinco ever manufactured the M305s with the cut out for the full auto connecting arm. I had licked mine up at a local gun show and it came with one. Every norinco I have seen is missing the cut out. After pulling the rifle apart the only markings I found on my oprod is a 4 digit number. No manufacture marks like on my M1 Garand.

The reason I'm asking is because I came across a GI oprod and I didn't want to rebuy something I already had.

Cheers

yes , china did produce some oprods with the cut out for the FA connector rod. The 4 digit serial number is also an indicator of a chinese part.
USGI oprods will have the USGI drawing number
 
There also oprods made over seas (not china) ..... the name escapes me but they are excellent quality and also bear a usgi drawing number. Dlask was at least one dealer in canada that offered them for a time and iirc also used by several US M14 makers in lieu of USGI oprods.
 
Also, if I recall, only TRW forged one piece op rods, the rest of the USGI op rods are two piece welded. Norinco op rods get short shrift, but they are one piece forgings...so if the pad is good, use it!
 
the offshore (non china) oprods are also 1 piece forgings.
I agree with machman though.... there is nothing wrong with a properly machined norinco oprod
if it fits good and functions as it should, there's no "need" to change it out.
 
It was "RWB" of korea that I was thinking of. These are the oprods commonly used by LRB and perhaps others.

here is an excerpt from the global m14 expert Lee Emerson also known on the forums as "different"

TRW operating rods were marked 7267064 with TRW underneath. Likewise for Winchester, 7267064 with its CAGE Code, 66118, underneath.

Commercial SA, Inc. versus USGI Springfield Armory - 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.

Saco-Lowell operating rods are marked 7267064 with SAK underneath the part number.

Mercury Tool & Machine operating rods have the marking: top line - 7267064 bottom line - MFR 24411.

Smith Enterprise, Inc. (Tempe, ##) - 7267064 with the CAGE Code, 3A5E1, underneath the part number

Thrustline Manufacturing, Inc. (Ogden, UT) - 7267064 with the CAGE Code, 4JNK8, underneath the part number

Mainland Chinese M14 operating rods are unmarked except often there is an electro penciled five or six digit number on the inboard side of the rear half.

Republic of Korea - These operating rods were marked in one of three ways:

a) 7267064 with 18242 underneath the part number
b) a very few of the imported operating rods were marked, upside down, 7267064 TRW
c) only marked 7267064

*** edit to add that the chinese oprods started showing up with a well defined 4 digit number matching the last 4 of the serial number sometime after 2007
