hey guys -I’m trying to get the size of the breech oring for the Daystate .303 Wolverine -
ive tried the internet but can’t find a difinitive size -also tried AOA -

my local Hardware store has tons of orings in Standard and metric - 
thanks

Try the metric 010 it is just a little fatter in diameter , once you get it in 
the barrel make sure it's seated in the o-ring groove as good as you can 
its seals very well . Good luck .
