Hell-o everyone today is my first day as a new member. I have to start off with a question. I purchased a 1077 a couple of days ago and the Crosman co2 cylinders. When I attempted to charge the system I turned the rod by hand and it would not charge,I then used a screwdriver and tightened it down more still no luck finally I had to use a pair of channel-lock pliers and and really crank down on the rod and it finally charged the system. Is this normal or do I need the return the rifle for some type of adjustments? Thanks to all for any help on this problem. SgtTip

Is this your first co2 gun? Normally you just finger tight it then pull the trigger so it can pierce the cartridge. Well maybe not pierce but to start shooting.

Yes thats what I thought and that was why I was suprised that it took such a effort to get the cylinder to pierce and charge. I figured if it takes that much effort that a wrench or tool would have been provided by Crosman. Sgt Tip

That sounds a bit excessive to get the piercing pin to penetrate the Co² cartridge!

The 1077 is perhaps not the easiest Co² gun to get the cartridge pierced- but certainly channel-locks should not be required!

Did you try another cartridge/caplet to see if it was as difficult to install and get gas flowing? Whose brand were the cartridges (i.e. Crosman or someone else's)? Most should be fine- but with a "no name" generic cartridge I would think the chances of QC problems would be greater and perhaps the metal cap that must be penetrated was not fastened securely or was too thick to allow the piercing pin to do its job properly.

It may also be the "piercing pin" which is a rigid steel pin which knocks through the caplet's cover to let gas flow may be bent or dulled. If the gun was on the shelf for quite awhile- it may also be possible the pin became slightly rusted. Try putting a small bit of oil on the end of another 12g cartridge and installing it and see if this works any better. If not- return the gun for another is my suggestion. Also- look at the end of the cartridge you installed with the channel locks and see how the end looks- is it ragged, or is the hole relatively straight through and even?

I would take it back then, shouldn't need a tool box to fire your gun.

I purchased the Crosman co2 cylinders thinking they were the best . I bought a 5 pack and tried 3 thinking maybe the cylinders had a problem and finally went to the screw driver then pliers.I noticed that the nut did contact he bottom of the sleeve until the use of the pliers which finally pierced the cylinder. Its good to be here. Day one and already help is available. Thanks to all. Sgt Tip
