S510 Ultimate Sporter Barrel Adaptor and Carbon Sleeve Set.

Replaces the existing barrel shroud and allows the use of a silencer.
The 1/2" unf barrel adaptor is fitted to the barrel to provide good concentricity and eliminates the issues of 'clipping' when fitting silencers to the factory shroud.
A supporting collar screws on to the action to support the carbon sleeve at the breech end of the barrel. O-rings fitted to the adaptor and support collar provide a snug fit to the carbon sleeve.
A compatible airstripper is also available.

Please note these items do not fit FAC rifles.
