A voice from the past whispers in my ear, “Brethren, keep your powder dry.”
From the way it looks the barrel should not need to be pulled unless you want to have a US made MSG90/ PSG1 trunion installed instead of a trunion extension. Personally I would not pull the barrel unless I was going to replace it. If it shoots good then I would just add the extension so the forearm is correctly supported. As they say.... "If it aint broke don't fix it".
I just sold a spare IGF US made PSG1/ MSG90 trunnion extension to another member last October.

It looks like you have a really good start for your clone build. Now it just depends on how far you want to go with it.
You could add the receiver rails, silent bolt close, PSG 1 lower, PSG 1 trigger group and PSG 1 stock. Which would make an awesome clone but it would also be really expensive.
A much more affordable route would be to just build more of a precision Hk91 rather than a true PSG clone. Send a HK91 lower and trigger group to Williams trigger specialties for either his standard set trigger or his SG1 style set trigger and add a Mag Pul PRS2 stock. It will probably be a pretty accurate rifle either way.
I can not tell for sure just by looking which barrel you have. However, if your upper was put together around the time those receivers were imported there is a real possibility that might be an Urbach barrel (There may be some people on here that can tell from the photos). There were not many parts for PSG 1 and MSG 90 clone builds until fairly recently (The last 10 years or so). Back in the day there weren't very many PSG1 clone barrels to get and sometimes you had to wait a very long time to get one. Of course I guess it could just be a custom heavy barrel that someone had made but finding someone that can flute the chamber of an HK barrel is not an easy thing.
Thanks for the tip on the barrel, I will go down the internet wormhole and research that.
Case in point: there were SR9's on Gunbroker recently that had PSG1 trigger groups, stocks and so on. They sat around for awhile at the $3500 level and finally sold. Market price for all the PSG parts and furniture would have fetched probably $2000. So $1500 for an SR9 barreled receiver? Kind of a steal from that perspective.
Own: HK91, SP5k, G36k, HK416, P30L, 2x P8, P8A1, USP SD, USP9, USP9 FDE
Future: SP5? Assuming I can find an honest seller.
FWIW - I have a correct Dyer MSG90A1 on an hk receiver - was a labor of love that took me years to find all the parts including bolt carrier group and Hensoldt etc. has forward assist, free floated front site, and uses an Urbach barrel from when Murray was still cranking them out. I love the gun, it is very accurate but it was very expensive to build over 10 years ago. No idea what it would cost now, but it probably is crazy money.
If you think you have a decent barrel there then I say it is worth it to go with correct factory lower, trigger and stock which can be parted and sold separately and will hold their value. I would not bother with the rest of the more expensive permanent upgrades. You will still have a good, fun shooter and you can get your money out when you decide you have had enough. My $0.02.
