HR-N is a typical marking for H&R trigger group housings.
I have an op rod that I purchased on-line that was represented as an USGI Springfield Armory op rod that is marked:SNIPERSRULE said:A USGI Springfield Armory op rod is marked as follows: 7267064 SA
all on one line.
The SA op rod has no notch. It was advertised on eBay as USGI, but I think the seller really thought it was USGI. It is in excellent shape with minor wear on finish. I paid $100 for the part. I feel the buyer would make it good, but I think I will keep it as a spare. Are there any issues with the commercial SA op rod one needs to be aware of when assembling to a M14 build project?Different said:Bill is correct. I have a 1984 commercial Springfield Armory, Inc. operating rod with no notch that is marked 7267064 on the first line and SA centered below on the second line.
Does the -2 after the drawing number on the new SA Inc op-rods correspond to their inclusion of the notch in the rear? In other words, did SA Inc start using the -2 when they started including the notch?Different said:Another way to tell if you have a commercial reproduction operating rod is the lack of a notch just under the handle. Beginning in about 1999, SA, Inc. had that notch put in their operating rods but the point is that if the notch is lacking, it's commercial reproduction.
Bill is correct. I have a 1984 commercial Springfield Armory, Inc. operating rod with no notch that is marked 7267064 on the first line and SA centered below on the second line.
