This is a spacer that centers the inner barrel inside the silencer and prevents it from wobbling when a custom-sized inner barrel is installed.
Spacer inner diameter 8.6mm
KM Planning 30 Featherweight Silencer Series - Universal Fit
When installing, it is necessary to cut the special sound-absorbing material inside the silencer and remove the sound-absorbing material for the spacer installation.
*This has been upgraded to a two-point O-ring design instead of a knurled design, improving centering accuracy.
If it is difficult to insert the silencer, apply a thin layer of silicone spray to the O-ring and then assemble it.
