Yes Allan, just to confirm Mr acropolite's info, i just checked my synta 10" tube rings and both sides of mine are 1/4" B.S.W (British standard Whitworth) threads 20 t.p.i.
The only thread that is 6mm is the tube rings for my ed80 and they are M6x1mm on one side and 1/4 B.S.W. on the other. Hope this helps.
