Description
Enhance the performance of your 1077 CO2 air rifle. The exclusive AirSource 1077 adapter fits into the existing Powerlet port, allowing you to easily switch back and forth from Powerlets to Airsource. When you upgrade your 1077 to an Airsource 1077 you'll get:
- Increased Accuracy
- More consistent velocity
- Up to ten times the number of shots compared to standard 12g Powerlet.
- Will only work on 1077's made after 1999
To determine if your gun was manufactured after 1999, simply look at the serial number stamped on the bottom of the triggerguard. The first three or four digits of your serial number indicate when the gun was manufactured. For example, if your gun was made in June of 1999, then the first three digits would be 699. If it was manufactured in December of 1999 the first four digits would be 1299 or it might start with a letter, D99

7 of 7 Crosman AirSource 1077 adapter upgrade Reviews
great idea, love the valve so you can turn the tank off and remove when done shooting without having to empty tank.
Things I Would Have Changedive been through 3 of these adapters and about 8 co2 tanks and 2 guns, cannot get any of these adapters to seal. wish i could, just been using the tiny cartridges
What Others Should Knowwish i had a setup that worked, the upper tube that goes into the forestock wasnt long enough to seal in my guns and all the co2 would dump out once cartridge is punctured. and yes i had the adapter screwed on all the way
Built very well, works as claimed.
Things I Would Have ChangedReplace the cover with a molded rubber grip that would take up the space between the bottle and the installed grip. This would spport the bottle if the gun is dropped. Cheaper bottles.
What Others Should KnowThere is quite a bit of CO2 that remains in the tube after the valve on the adaptor is closed. The bottles are costly.
I liked the fact I could shoot more than one time without the velocity dropping off. With the 12 gram CO2 powerlets I had to wait 30 seconds between shots in 85 to 90 deg weather.
Things I Would Have ChangedMaybe lighter in weight.
Love the amount of shots per fill. Gives a better balance to the gun although admittedly adds a good amount of weight.
Things I Would Have ChangedNothing, although the airsource upgrade just screams for someone to make a 100-rd clip for the 1077. I have some plans......
What Others Should Knowappears to use less CO2 per shot than a regular cartridge. This may affect velocity/accuracy. Noticeably heavier. Lots of fun. Pick up 10 clips or so, and 40 magazines, spend an hour loading them up and go plinking!
John from USA this makes the 1077 a lot more fun. I should have gjotten this with the gun. It really works well.
Things I Would Have ChangedNothing
Affordable and makes this gun fun.
Things I Would Have ChangedMake the nice sleeve read the same instead of one side normal and the other upside down. Also make it available separately.
What Others Should KnowIf you run a bunch of magazines this too will freeze and you will loose power without a break in between.

Once in place you can shoot the gun to your heart's content, it lasts long.
Things I Would Have ChangedMake it a little less bulky if they could.
What Others Should KnowI had no trouble with the item. You can shoot for ever and not run out of CO2. I liked the valve to remove the system when you want and you can still shoot for a bit before removing the adapter. Why waste the gas as I can tell when the pellets start dropping and quite then. The only down side is the gun seemed to have less over all power than with the 12gr. Powerlet. Why? I don't know. It just seemed to but that power remained consistant throught the use of the cylinder. Great item if you want to shoot all day and it worked great in my indoor range as high power didn't matter.
