Custom made screw on adapter with thread protector to attach a silencer/moderator to your Webley Mastiff and Edgar Brothers Arms EV2 airgun.
The screw on is plastic, but the silencer thread is metal, size 1/2" 20 tpi (UNF).
This sale is for Adapter only, which is a replacement of the original front cap.
Fitting instructions:
Remove the original front cap and replace it with the new adapter. Make sure you don not cross thread when fitting it, tighten it by hand.
