Although i do not own, nor am i able to(age) own, a silencer, I will be getting one ASAP. The thing i find is the bolt go to the rear with substantial energy and makes a pretty noticeable noise. It also does this to the chamber and bolt-face. There's polycarb bolt buffers but I'm not too keen on a plastic piece hanging over the trigger box. I've never had too much luck with plastic internal parts. Has anyone tried to quiet the bolt with rubber on the rear of the bolt? Or on the front for that matter? Is it a good idea to cut a bolt buffer out of sheet rubber and try that?
