Does anyone know if a thread adapter is commercially available to attach a .578-28 can on a .625-24 barrel thread? My Olympic .45 ACP upper barrel is too short to cut off the existing threads without doing a SBR.
the sizes are too close to make an adapter which is typically made one inside the other. One in front of the other add too much length to go into a suppressor and may cause baffle strikes. cut your barrel back and thread it 5/8x24.
