Drozd Bumble Bee help please

[Lobi]

So I was able to score an all black bumble bee. Loaded batteries, bb's, and CO2 last night and started grinning!
This morning when I went back for a second helping of fun the CO2 had all leaked out. I put in a new cartridge and she was leaking immediately. Pretty sure it's within the magazine. Upon teardown I see that there is no seal where the cartridge makes contact with the piercer. Shouldn't there be a flat o-ring there to seal against the top of the cartridge? Is this a Drozd specific part or is there a generic seal available? Part number or link would be awesome. Maybe other seals in the mag are due for replacement anyway but this seems like a starting point.
Thanks in advance

You could always try a generic o-ring & see if it works. Might be an easy fix. No harm in trying.

Well, I tried dropping a couple in but they didn't fill the void. Also weren't tight to the piercing stem. Seems like they would fall out with every cartridge change. Seems like correct one would be snug and captured.

The leak is very tiny and not at the cartridge. I need the tiny seals for inside the top of the magazine.

Anybody know where to get em?

I found this pic from an ebay seller but $50 for a couple little o-rings is silly.
I guess I'll try taking it apart and go see what I can find at the hardware store.

You talking about the o-ring on top of the co2 chamber?

I don't think that one is leaking. I think it is #1 or #2 at the valve from the pic above your post. The leak is very slow. I can shoot it but it doesn't hold air overnight. Hopefully can find em all.

I just measured some spare (#1/2) o-rings. You can order them from the oring store for about $15 shipped. You’ll enough to last two life times.

Well, I fiddled with it a little more last night and discovered that the screw in retainer at the top back of the magazine (for valve stem?) Was not tight. Pulled it apart, did a little cleaning and lubricating, and put it back to together. With a new CO2 cartridge installed it didn't seem to be leaking, at least to my old ears. Took a few shots and hung it on the wall.
This morning, to my delight, it was still holding pressure and shooting fine!
