RAW Rapid Raw 9mm silencers questions

[etiam.viviens]

I have a 9 mm Raw barrel with a silencer that I want to remove/change. The aluminum piece is stuck and there there is no movement. I am now wondered if that piece is threaded or shrink fit on barrel. Does any knows this before I break it trying to remove it.

That doesn't look like anything that Martin would install. And there appears to be an abundance of epoxy holding it on. Some epoxy will break free if frozen overnight. Otherwise, heat.

Propane torch heat it pretty hot, Rod or screwdriver threw vent holes and twist !!

* Don't burn yourself !!!

** Take out any set screws first

So they the barrel is threaded, thanks that's good to know.
Does someone know what kind of thread it is?

My experience ... Slip fit with JB weld epoxy holding it. No threads

Thanks

Like Motörhead said. Slip fit. Heat and pull it off.

Mine the slip fit was really tight to put back on at the last bit. Give it some heat when you put it back on. It will drop right on and let it cool.

Actually this looks exactly like how Martin does the older RAW integrated moderators on the barrel. There is excessive epoxy on the aluminum air stripper, but it may have been redone after it was built. Use a torch or heat gun as mentioned to remove the aluminum air stripper.

BTW, I have found that Martins integrated moderators with the air stripper and stacked chambers work very well and do not affect accuracy at all. I believe they work better than most screw-on moderators you can buy.

This one works great but It needs to move forward as it in the way when I place a inline Plenum.
I used a 400cc Theoben bottle for testing but would like to place an 580cc carbon bottle so I need to modified it.

First step is to move the backpiece of the moderator forward and hope its still effectief and if not I will need an new moderators

That back piece looks to be a weight having to do with barrel harmonics . personally i would not move it , might lose accuracy. end up with a shotgun pattern ?

Its the part that is in the way after I have placed the plenum, and the moderator tube is screwed on that part.
I do not think its a weight for the harmonics, but I will see when its done.

It’s not a weight. It’s an aluminum adapter for the back of the shroud.
