Okay, this may take a while to have done...but have Jeff source a custom barrel for your build. He can have it nitrided.
I had him source a 1/9 barrel from a guy who turns barrels to his spec. Since a Galil by any other name is still essentially an AK, I personally wouldn't worry about running super heavy ammo like 72 and 77 grain,etc. Mine's runs 55 and 62 with equal and GREAT accuracy. I mean STUPID accurate. (This is just my personal preference, you go with the twist that YOU are comfortable with)
The only thing I can't advise you on is a trigger. I tried both the stock trigger and the ALG....both are typical AK sloppy. That is just inherent in the design. I will try a Red Star Arms trigger...maybe later this year...but since I got laid off due to this COVID bullshit, I have to wait a while before I can get back into the game.
I think you will be much better off with the Tortort than the CNC Warrior.....though my issues were NOT the fault of CNC Warrior...it had to do with print revisions on my kit ( same as yours ) versus the specs and print revision that the CNC Warrior was built to. (there were a couple major print changes over time, as I understand it)
Regardless, Jeff got it all ironed out and my gun is a SHOOTER!!! A solid, solid shooter!
Anyhow, here is my masterpiece that Jeff built for me:
This may not be cheap...but I am telling you, it WILL be worth it. I HATE everything AK...and I utterly LOVE this gun. LOVE IT!!!!
By the way, Jeff can source handguards for you if you want the wood ones. Mine came to me very white and unfinished which was exactly what I wanted because I wanted to stain the guards to look oil soaked and aged
