No matter how lightly I touched a barrel with 2 fingers when my son shot it with my eyes closed and becoming one with the barrel I never felt any vibrations.
Wrap your barrel in stretched vinyl or electrical tape. It will be completely dead. No matter how thick the metal it it will transmit vibration. what you need to do is dampen it. Like holding a bell when ringing it compared to making it thicker for an extreme example the science supports it. Want to eliminate vibration wrap the barrel not buy a thicker one. Or buy a thicker one and wrap that one.
If the outer barrel OD is different just drill the end cap. I had to for an Edgi Barrel.
Perhaps someone else can comment of shooting better however.
