Breech O Rings Help

So I know everyone says to use 90 Durometer rings, but are those the ones they carry at Ace Hardware?

I found some that are the right size there (7/16*5/16*1/16) but are these the right durometer?? It didn’t say anywhere on the box there. Are these ok to use?

Hi, the O rings at Ace are 70 durometer. I can sell you 10 of the 90 durometer O rings for your breech for $2.75, shipped if you want.

quote Voltar_1:

If they are not labeled as 90 it is safe to presume they are NOT.
likely only 70 duro at best.

I would agree. That being said though, they are fine to use, just not as durable as the 90 duro ones. Probably equivilant to the factory AF o-rings
