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

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!
