Bed Wetter I am going to PM you with an idea and give you the number of a gun smith in Michigan that may be able to help you.
I have another concern about adding a suppressor to a thinner barrel: harmonics. Thinner barrels have a considerable amount of “whip” and I can’t wrap my head around how putting a 1lb can on the end of the barrel wouldn’t jack up the natural harmonics of the barrel. I don’t know what it would mean for accuracy and so far I haven’t been able to find much info on it. Everyone says that “POI will shift a little,” but that’s a broad statement.
The fact of the matter is, there’s not enough experience out there with silencers yet to definitively answer these questions and I’m too much of a novice to figure it out myself. If there were more knowledge about silencers, you wouldn’t see major manufacturers like Remington, S&W, Ruger, and Kimber putting threads on rifles that don’t allow a silencer to be mounted.
Oh yeah, that’s another thing: if a barrel is threaded and the manufacturer says it’s “suppressor ready” that’s probably BS. Pretty much every rifle I encounter with factory threads requires additional machine work in order for the suppressor or muzzle device to mount flush against the shoulder. Pre-threaded barrels are worthless and it’s mind-boggling that manufacturers don’t know it.
Edit: All of my ARs with adjustable gas blocks are designed from the ground up to host a silencer. Those rifles are threaded correctly. The typical “sportsman’s” guns thread barrels as an afterthought.
