There not, not that it matters.




I didn't know rifles had feelings?
Only if you gave it a Girls name. Than of course it does.

On another note is see this is a common malady with the M1A. I wounder if it is limited to only SA OP Rods of do they ,for the most part all get a chip there?

I would like to hear from people with non ( dreaded ) SA Op Rods to see if they in fact see it as well.

Mine has that too. Check to see if your spring tube hits your stock liner prongs that are below. I had a buffer in there until I had cycling issues. It was due to my reloading. So a buffer might provide some clearance preventing the op rod from hitting the receiver. But the concensus is that it's no big deal either. I haven't put the buffer or sadlak guide back into my rifle yet.

My prongs hit as well. Just poor QC. Good thing is by the time you find it ,like the Op Rod ding the Gun has settled in and this issues cease to be a problem.

I have an H&R op-rod in mine. It does show where it's been contacting the receiver in that area, but there is no chip. There is some metal that looks like it's been displaced, though.

I was always under the impression the commercial op-rods SAI uses were one-piece forgings made in Korea.

This isn't the case?

nah I'm pretty sure they're castings made by wayne machine in Taiwan along with most every thing else but, the receiver and, the barrel (right Phil ?) or that's what I read on the internet which never lies.By the way all my springfields done the same thing around the one hundred round count and none of my polys have but,I can't tell that it has hurt any thing just dress it up with a needle file and don't worry it's normal

I was looking for a Poly (because i thought SAs were too much Money). But NOOOOO! My Wife said "Buy a real one not a knock off"! So i did.
See the knock offs don't have this problem.
Who would have known? GI3
BTW
Yes she paid 1/3rd of my SA.

The USGI receiver blueprint calls for 45 degree chamfer on the top forward edge of the receiver op rod rail, to clear the rod at its max reward travel . Most commercial receivers do not have enough or proper relief there. Easy fix with diamond EZ-LAP stone.

So that explains why this is very common on SAI M1A's.

But since everyone is saying this ding causes no problems. I ain't going to try and fix it.
