safely , we can assume about 1000psi , but i hear that much more the valve might turn to shrapnel.

... I've used my AS1077 in 90-95 weather, and I'm still alive ...

... I believe that temperature will push co2 pressures way over 1000 psi, and mine has still not blown up.

BTW I refill my 88gr tanks using B&A adapters, work great ... got one with adapter attached to a 2250XT since last summer and it still holds gas.

you're scared ? go get a dog ... I'd rather die standing than live on my knees

thats about 1080 psi , i too have shot one mid summer

im sure there is a 2x safety factor , so max burst would be 2160psi, but thats assuming crosman ever thought people would hpa the guns , otherwise the fail point might be 1200-1300 ALL SPECULATION AND POSTULATION ON MY PART

... adapter works like a co2 pin valve ...

Just install it on any empty 88gr tank and refill it just like any paintball tank, just need to carefully weight them to prevent overfilling (they don't have a safety burst disk).

PD: this will also allow you to remove the tank from the gun without emptying the 88gr tank ... just unscrew about 1 to 1-1/2 turn, fire once or twice to empty the valve, then finish unscrewing the 88gr. Be sure the adapter does not unscrew from the tank, they do have a setscrew to secure them but better be safe than sorry, I marked mine so you can tell if the adapter becomes loose - it will become an unguided missile if they do come apart, not a funny scene.
