I am trying to lower the recoil of my 308 and didn’t know which of the two would be better. I’m using a PRS gen 3 with a carbine buffer setup currently, so I can use the rifle or carbine length buffer tube. I know the JP SC spring is only carbine length and you add a spacer for rifle buffer tubes. Does the JP spring make that much difference in the recoil vs a standard full length rifle buffer and spring? I have an adjustable gas block on my rifle and that helps as is.
