I have adapter spacer but I’m not sure which spring to use , that’s reason why I ask if someone try already...

You would want to use whatever spring works best for your pcc and the load you have developed for it. Since you are using a spacer it makes the internal dimensions of the rifle  buffer tube into a carbine buffer tube and there is not one “go to” spring for everyone. Best bet is to buy multiple springs and try them out and see which gives you the best performance.

Hello: Use a 308 rifle spring. It will shorten the stroke a little with a spacer but it still will lock the bolt back. I am using a JP 308 rifle spring but any should work. Thanks, Eric

I have an A5 length tube with a stack of quarters in the bottom as a spacer, making it the same as a carbine length tube.

I just tested the difference between the 308 carbine length spring, and the 308 rifle length spring.

 

I am keeping the 308 rifle spring.
