Has anyone taken the plastic silencer off of a Remington Express XP or Sabre?

If the intention is to fit a good slip on mod, there would be no need to machine down in to the grooves,
simply turn it down until the surface is level with the rest of the barrel, & then cover the area with a slip-on mod.
Not perfect, but an option.

The area under the mod is a smaller diameter than the good section of the barrel
Turning it down will likely:-
1) produce a section that is too thin to be strong enough and / or
2) after the addition of a slip on moderator, leave you with a ridiculously long barrel
Hence my advice remains carbine it and add a slip on moderator

Shame you didn't provide that gem as part of your first post on the subject
