I've measured mine tonight (sounds a bit dodgy) and it is 23mm, luckily I was polishing them all up again and had me tools handy with a diameter gauge in there.
I've got my Kraken now paired with the Origin brass and my KFL is paired with the Nemesis mixed, found out what the poor firing was, the little guide pin had become tarnished and that is the main power contact for the switch, cleaned it up and toking away on me Nemmy
My Sentinel M16 Alloy and brass, the alloy sections are 23.5mm I've just found out if thats helpful for a matched set.
