Any one use Game Face co2 cartridges? I bought a 15 pak and so far everyone has leaked in my 1077. So much for a cheap price.

Good day;
Although I have not used Game Face Air Source bottles I am going to guess that, since they screw into the Crosman Air Source Adapter OK, the problem is the positioning of the inner Adapter 'O' ring.
Unlike a 12 GR, they do not seat "on the flat", but around the perimeter of the bottle neck with an 'O' ring.
The proper positioning of the ring is fully within it's seat, toward the bottom of the adapter barrel.
If it is in the adapter, but not seated in the proper groove toward the bottom (as mine came from the factory), then roll it downward on all sides till it seats uniformly into the groove it was made for.
Of course, if the Crosman 'O' ring is not in the adapter at all, that is another matter (you need one).
Regards;

These are the 12g co'2s are you saying there should be an "O" ring to seat them on? Anyone happen to have a schmitic (sp?)?

Having same problem, when i screw in a bottle the needle punctures the top and pressures the o-ring pushing o-ring back against the threads, the threads are getting nicked, starts to leak when sitting, will start to leak and can tighten it some, this has cost me 4 can's, will be calling crosman in morning, have replaced the o-ring once and happened again, it is a AS1077 with scope, love the gun otherwise, it is a Canadian model so the power is a little soft but hopefully someone can help, have read about lots of tricks here already, this is one great site, and I am a newby
