Original or Reparkerized M14 Op-Rods

I buy a lot of M14 parts, mostly from GunBroker, or individuals here in the px. I have been taken just a few times, once when I was a newby here on this forum. Another time, I was told that the op-rod being offered to me was in its original condition, that too came from a forum member. On that particular occasion I was fine with it because other than having been refinished it was a very nice hard to find SA. op-rod. That particular person, would have taken it back I am sure but, like I said its a hard part to find.

Anyways, I thought I would share with you folks here, how I inspect parts to determine if they are what the seller says they are.

Buying an op-rod can be a bit tricky, because not only are they refinished, retabbed, but are also rewelded from a demilled op-rod.

One of the easiest ways to tell if an op-rod has been rewelded is to wipe it down with acetone, it will remove the cold blue, as the weld won't take park.
I had that happen once, and the guy quickly gave me my money back.

Another tail tail sign is when a part is getting prepped for park it gets bead blasted to remove the old finish, this bead blasting not only removes the park but some of the metal from the part. If the tab has be replaced, it should be easy to tel as the weld around the new tab won't take parkerizing.

Another area that I inspect of the op-rod is the area holding the bolt roller, in this area on a new or untouched op-rod you can see where it was routed out by the router leaving a distinct pattern.

I took photos of four available op-rod, two have had this area blasted clean, one is very faint and the other is as it left the factory.

The first picture is of the only new op-rod I have ever had. It is a Winchester. The routing line is clearly visible.




This one is a TRW it was retabbed and refinished, the routing line is barely visable.

In this picture you can tell which is the TRW, the other is an SA.


These pictures are of the SA. Op-Rods, both have been refinished.


Hope this helps.

Is there some mechanical benefit to refinishing (or not) or it that just a way you identify the manufacturer?

There are many advantages to knowing how to tell if a part has been refinished rebuilt redone.

1. People will sell you a bill of goods if you let them, being armed with knowledge will keep you from being taken. I don’t know about you, but I want to get what I pay for.
2. I don’t want a rewelded anything particularly if it is being sold to me as original, that’s just me.
3. Most M14 parts are unmarked, therefore, machining maybe the only way to tell who made it. Again that may not matter to you, but I can assure you there are those it does matter to.
4. I have heard tales and experienced it once first hand, you are not always guaranteed to receive the parts you sent. Knowing how to tell will keep honest people honest.
5. I enjoy studying anything M14 related, if this helps me to understand better what it is I am looking at, more power to me.
6. I am not to old too chase women, just too old to catch any. So I do this, that maybe the best reason.

YMMV

I have learned a lot from Ren and saved myself a lot of heartaches and money by being armed with knowledge.

Many will try to take advantage of folks and sell parts that are not as described [not so much on this forum] but many out there will try to take advantage.

Learning and researching is the fun part and it never ends, I learn something new everyday!!

Yes it can be difficult to differentiate between original and reparkerized parts.

Ren, PFC's post was not a pot shot, so don't take it as such.

Heres another tip, if you are trying to figure out if your Trigger Housing has been reparked take a look at the magazine latch spring, it should be in the white, NOT PARKERIZED.

This is a new from wrap SA. trigger housing opened by yours truly.
You should be able to see the spring I am talking about. This isn't the only way, just one way. The lack of milling marks is a great indicator of a reparked part. Again, you may know other ways to identify reparks.

Oh, and yes there are guys out there that can do it right, making this much more difficult. The good news is most won't got to the trouble, much more time consuming.




If yours is parked, your trigger housing has been reparkerized.

I would remove that spring before park and I wouldn't remove mill Mark's when knocking off the old finish. I would not try to sell it as original though, if someone is wanting original finish best know what your looking at. Personally all I want is a good finish.

I didn't take pfc as being offensive. Old parts can be made to look new.

I agree, reparked parts can be difficult to identify, I think anyone can be fooled, I include myself in that statement. Still there are tactics we can use to help us make informed decisions.

I have use quite a few new and way more re-parked and even more used op rods over the years and never noticed one iota of difference in function.
At times telling the difference, even for the real experts is " almost " impossible.

This op rod is a reconditioned H&R.



This is brand new RWB.

Yes, that thread was much appreciated, though not M14 parts, the info is still applicable. It is threads like this that I value most, it helps those who are into the history and collecting these weapons.

Thanks Orlando, your knowledge and willingness to share is much appreciated!
