Welcome aboard first of all.
My feelings are similar with 300 Whisper. I think it's an excellent cartridge in the AR15 for close range carbine marksmanship, especially in confined spaces, indoors, or tight ranges where overpressure can be an issue for your head and ears.
Lilja uses 1/8 twist.
I would consider sticking to the standard Stoner internal expansion operating system of the AR15.
A suppressed 6.5 Grendel with the JP Silent Capture Spring is really one smooth-shooting set-up. You can configure the buffer and spring weights on the SCS for your system.
I use it with my Lilja 18" Wasp barrel set-up, and it is extremely smooth, with no need for a muzzle brake, even with a very lightweight rifle.
