Blew out my barrel seal. What is the correct size and material for the 22 cal barrel seal?

"hsnmz"it is 5.28x1.78 PUR 70

Could you point me to a source? McMaster-Carr does not seem to have any 5.28 mm ID and 1.78 mm width o rings.

Tony this AS568 size which is the equivalent metric size. Note what the size in metric is on the 009 NBR 70 I bought. Just be sure to get the urethane version of 009 U90

Bill,
Many thanks. I ordered some from the O-ring store.

Bill,
purchased and installed the O-ring with the aid of a wooden dowel in the bore. My favorite rifle is back in business.
Thanks again, 
Tony
