Multi-cal vs dedicated experience (silencers)

[MegademiC]

Hosts: 9mm machinegun, ak, 223 precision rifle, 6.5cm precision rifle

Im currently considering either:
1. Silencerco 36M OR
2. Yhm R9 for subgun/AK,
And something else (vox s, DA nomad, socom260Ti, etc) for 6.5/556.

Main questions/concerns:
1. Will I be happy with 36M suppression in a 6.5/556? (Assume long with dedicated end cap)
2. Will a 7” x 1.6” silencer be a noticeable performance difference in the sound vs my revolution9?

Edited to remove the BS and get to the point
