400 SHOTS PER CYLINDER! This kit allows you to use the Airsource 4 oz. bottles for your 1077. Fits right in where your CO2 cartridge goes. Includes adapter, black cylinder cover and one 4oz. cylinder.
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

Things I liked:

Once in place you can shoot the gun to your heart's content, it lasts long.

Things I would have changed:

Make it a little less bulky if they could.

What others should know:

I 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.

Things I liked:

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 changed:

ive 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 know:

wish 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

Rating 5.05.0 5.0

Things I liked:

Built very well, works as claimed.

Things I would have changed:

Replace 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 know:

There is quite a bit of CO2 that remains in the tube after the valve on the adaptor is closed. The bottles are costly.
