Forget springco's garbage nonsense and stick with the correct parts. Eff me!
Well . . .
All I know is that the original AR-15 from 1958 to circa 1967 were a single 5 coil music wire spring.
They didn't last very long, so they went with a pair of nested springs until 1972(ish)
Then they went to the four coil spring with a rubber buffer.
With the M4 they changed the buffer to a stiffer material.
Then they went to the gold spring made from heavier wire.
All of these changes were accompanied by exhaustive testing.
I am not a MIL-Spec for MIL-Spec sake kind'a guy, but if I want something that I know is "good enough to sake my life on", I know where to go. I also have a good idea of how long it will last (18 to 36 thousand rounds), and that is good enough for me. . .
Not sure if there are as many different extractor springs as there are BCG's?
However the two most recommended are the Colt gold and the Sprinco. The Colt spring quality is not controversial while there is some controversy over the Sprinco.
That being said I have not seen any evidence that the Sprinco extractor spring is not equally as good as the Colt Spring.
A direct comparison test would be interesting...
How much money do you want to bet? The reason I swapped them to Sprinco in the first place is because I had one that needed to be replaced. It had almost no tension to it whatsoever and ejection was weak. When I did it I changed my extractor and ejector springs in all of my guns to just be done with it.
I don’t think it falling for hype because someone seeks to use the best parts available to them. So far no one has any actual reasons on why they dislike Sprinco or negative experiences they’ve had with them.
