Thread: Suppressor-over barrel or barrel forward

Re the rear delrin bush, I've had rifles come back from from fitting by reputable silencer manufactures with a slight clearance and I've also had experienced gun smiths recommend that they be touching but not tight.
I could make an argument for both

Currently I have both on my rifles. Have not experienced any movement or rattling on the one with a small clearance. Once they are done up on the barrel they are firmly locked in place. I view the rear bush as being to prevent excess flex in the silencer and that as the barrel may not be perfectly centered relative to the thread on the end and wall thickness etc so a small gap stops the barrel being subject to any side loading by the silencer down up in different positions.
