IZH-46M breech seals

Has anyone found a source for the breech seals (o-rings) for the Izzy?  As of 2-23-22, all the usual air pistol purveyors are out and have no information about when the o-rings might arrive.

Have you tried Pilkington.

Try ebay.  There's a vendor named alexeybezporoxa.  I purchased seals from him a while back.

There, um, might be some delays getting things from the Russian Federation to the US these days...

Thank you GF207.  
I ordered from Alexey - but delivery won't be until sometime in late March or early April.  Patience is not my strong suit.
Thank you Chopper, but Pilkington is also out.

Purchased from Alexey in Russia off eBay, zero issues and arrived in about 3 weeks. I found a article about a fellow who casted his own with a mold he made which looked slick but is beyond my abilities. Upgrading the material to urethane or possibly a O-ring sounds good too. Not sure how the companies here want to charge so much for the OEM seals?
