When to use an extra power spring?
I've been perusing this fine forum for quite awhile and I've read most of the technical stickies. What I mean by extra power is something like a SpringCo blue spring. I've read the Tuning 101 and other discussions, but I didn't see a clear (to me answer to this). So I'll pose 3 questions.
1. How does one know when an extra power spring is necessary or preferable?
2. How does the spring tension interact with the BCG and buffer weight to impact the operation and performance of the rifle?
3. In what case would it be preferable to run a lighter carrier and buffer?
I hope these questions make sense to you guys, because it almost seems like an art to determine the best setup for each of my rifles and I want to understand what I'm doing as I tweak them.
Thanks
