I received a king swivel a couple of days ago and so today I tried installing it on my .303 longbranch. After getting about 3/4 way the screw stopped. I took it out and compared it with the original and the threading on the original is thicker. I thought maybe the canadian made .303 was made a little different, so I took my B.S.A. out and found that the original king screw had a thicker thread. Were there different types of king sling swivels made? Are there king swivels that will fit my .303's. Any help would be appreciated.
