Yes, I change all pieces without changing the barrel. My gunsmith did the work. I use an old hand guard from a GMR-15. The new vertical comp ”pin”/weld but a set screw hidden inside for an easy change if needed.

I have swap the parts and I really like the whole new set up more now.

I use these parts. This combo is super effective. 1) Smalley wave spring C100-H8 https://www.smalley.com/request-retaining-ring-and-wave-spring-samples 2) Kynshot RB5015HD 3) Strike Industries AR-10 Flat Wire Spring 4) A coin on top of wave spring

Exactly which wave spring and does the mechanism work just as well as before?

Kynshot in a JP5? Which one and which spring?

Agree

Yes, they are. Yesterday I tested the strongest AR-10 SCS and 60˚ and it worked together. I still do prefer S&B 115gr.

Yes, I have. Even S&B and Geco124gr. 115gr is little more snappier but those feels absolutely best. Next I will try an other SCS-spring.

I shoot S&B 115gr and I use Lock piece 60˚. This works even better than 70˚ but there is still room for improvement.

Yes, I'm also looking forward to seeing this photo. I think it is impossible.... Left: JP GMR-15 and Hipertouch Elite - Right JP-5

My gunsmith finally decided not to remove the barrel when changing the comp. The old comp was pin and weld. The new one is also pin and welded.
