I have very little hands on experience with the Sprinco spring. However, I did have a discussion on the subject with Will Larson who had extensive experience working on ARs (along with other families of weapons) in a combat zone as well as here in the US. He thought enough of the Sprinco spring that he recommended Sionics and SOLGW use them in their ARs. Will's bona fides were good enough that I recommend the Sprinco springs based on his say so. I haven't heard any complaints from anyone using the Sprinco spring.
I see no reason to replace a Sprinco spring with a Colt spring or vice versa.
Will passed away not long after I took his armorer's course. He is missed.
We were likely in the same class. Anyhow straight from the M4C archives 2019 by Will himself
[The Colt copper washed extractor spring is a good option, as is the Sprinco enhanced spring. I have also used (and still have) BCM enhanced springs as well. Any of them will work.]
Nuff said?
Go Ukraine! Piss on the Russian dead.
