It seems like a mandatory upgrade (along with the ORSG, which I have already replaced) but why does nobody talk about upgrading the Op Rod Spring? I'm going to get the CS David Tubb ORS and will report back once it arrives. It should be a vast improvement over the Norc spring? Anyone out there have any reports on what/if any effect a spring upgrade has?
David Tubb CS Op Rod Spring??

I replaced mine with a Stubbs just because they are supposed to last longer.
Never fired my rifle with the original spring.
Just remember there are size differences between stuff meant for the Chinese springs and american springs.
Chinese spring ids are smaller IIRC

Chromed Silicone springs rock. but it's not manditory unless you get a US manufactured aftermarket op-rod guide but if you by a domestic op-rod guide keep your nork if you don't want to waste your money.
Yup, the Norc springs are just fine. No need to upgrade that op rod spring!
Unless....
Once you drink the Sadlak Koolaid and buy a Sadlak NM op rod spring guide, then you MUST buy an American sourced spring (Brownells, M1A, Tubbs, wolfffff). And many of you who have played with my Norc shorty at the M14 Clinics, I have a Sadlak unit since I just could not refuse the KOOL Factor.
Save yer money , folks! But leave the cook stuff for me! ha ha ha ha

No issue with my spring swap.
So it sounds like the trigger spring is a definate improvement (3lbs doesn't sound unsafe to me...or was that a joke?) but I still wonder whether the Tubb Op Rod spring improves accuracy/performance due to it's superior construction. The Tubb website claims their spring is stronger and more consistent, would love to see a five shot group with Norinco and a five shot group with Tubb Op Rod Spring.....I may have to do this test myself!
Remember the black arrow was meant for chicom springs.
To be fair you would have to use a orsg made for american springs
Learn something....
The norinco spring is internally smaller. The osrg for these have to be smaller also. So you can put a smaller norc style osrg in an american spring. Problem is you end up with a little more slop. The reason you replace the stock osrg is to get ride of slop(bending of the spring).
So you can see it would not be a fair assessment.
Hoping someone more knowledgable will confirm this but from what Ive read theres a minimum safe weight for the m14. Dont take my word for it Im a Gunnewb. This guys a much respected m14 cat.
"What is the weight of the trigger pull? Measure it carefully …4 and 1/2 lbs is the absolute MINIMUM safe weight. If it is less than 4 ½ lbs, then the hammer may follow in some circumstances. … especially if the rifle is not held tightly against the shoulder. This is called BUMP firing."

I didnt measure mine but had read stuff like this and knew it was lower than 4.5
