hi, i purchased a 392AS c02 version, but it leaks all the air when screwing in the bottle, i think it needs a o ring in the bottom of the receiver near the piercing nipple, so the bottle end screws up against it, i ordered these.http://www.ebay.co.uk/itm/281325473403?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT (http://www.ebay.co.uk/itm/281325473403?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT)
but they are oversized and do not fit,need a smaller o ring,any one know which one to get,as its costing me money on bottles.

I have no knowledge of this rifle and was unable to find either an owner's manual or a schematic for it on the Crosman site.
I did however find a site in the UK which has the schematic and parts list.

Im thinking they dont have Harbor Freights across the pond...LOL...good luck

It might be worth checking a site like marcorubber (allorings.com) - they carry just about every imaginable size o-ring, including mil-spec stuff.
EDIT: I wouldn't be surprised if it takes the same size as the QB78.

I was researching a replacement seal for a 1077 AS Adapter today. Crosman part number is DMC4TA-006 I also found this information on it's dimensions and rigidity.
It has an OD of 18mm (23/32") and an ID of 12mm (15/32")- and a thickness of 3mm (1/8"). Both new and the old seal are fairly rigid. I don't know their durometer rating- but they are much harder than I had expected. I found a pic of a new o-ring too.
Hope this helps.
