Thread: Suppressor rear bush sizing

Even though I don't have any over barrel suppressors, but have owned a Savage with a terrible banana barrel.
The bore was straight and either end was concentric, but the middle was wildly off centre.
An armorer told me that this is not unusual even for premier rifles.
So out of curiosity, what do you do when the bush is only touching at one point on the barrel ?

Relieve it….open it up concentrically till it has clearance ie not touching all round…unskilled opinion….!
