As for being too new to need a breech seal, there is no such thing. O-rings and Seals tend to have a mind of their own and can fail without notice. Just a fact of life. It’s better to have some on hand just in case.

I get all of my o-rings from McMaster-Carr online. Awesome selection and will ship anyway you request which saves shipping costs. Polyurethane o-rings cost much more than Buna-N rings. For example:

-009 Polyurethane A70  ($7.24 for a 10 pack)
-009 Buna-N A70  ($2.08 for a 100 pack)

Tell me which rifle you have and what caliber and I will tell you the size and type of o-rings you will need.
