Buffer spring

[Klem]

It gets week causes feeding malfunctions can mess with timing issues like dwell time.

In the civilian world i dont think the rifle is shot enough for an issue. It could happen with competitive shooters but for the most part i dont think we shoot enough.

I've used them in the military and again, never heard or saw this. "Dwell time", with respect, that is starting to draw a long bow. How often civilians shoot relative to disciplined bodies is speculation. One can be convinced a concerning problem exists in order to justify the different and more expensive type of springs. And how do you know flat springs are a "bit stronger" than MILSPEC? I'm playing Devil's Advocate here to sift out the shiny but questionable kit and marketing hype.

You could invest the difference in an adjustable gas block instead. Stick with the cheap and cheerful MILSPEC spring and fine tune the pressures on the whole recoil system.

I have seen guns prepped for storage by releasing the buffer allowing the spring to expand forward. The buffer will rest against the released hammer. Then push it back in when you use it.
