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.

How do you disassemble the JP5 barrel? What tool do I need? The JP5 barrels isn’t like normal AR barrels…

We probably don´t have to wait many weeks before someone will test Kynshot and different springs :-)

Hipertouch Elite in all my rifles.

Hipertouch Elite works perfectly in my GMR-15. Also in my other JP rifles.

Which SCS setup is recommended for a 158 gr bullet at 1,033.46 fps (Subsonic Ammo)?

It does not have to be. Hiperfire triggers have a very good reputation for PCC. I also use Hipertouch Elite in both my JP SCR-11.

It depends on the shooting style you have. https://www.youtube.com/watch?v=dL2JWMSsyWQ&app=desktop

This is also my experience and that’s why I stay with 5 tungsten. My best splits are .12/.13. when I use HIPERTOUCH ELITE.

I prefer SCS 5H5 Heavy (Short Stroke) and I use 115 gr bullet from Sellier & Bellot factory ammo.

Thanks for the advice!
