The 1077 with the AirSource adapter makes a very versatile sporting airgun. It has accuracy and can use either 12-gram powerlets or the new 88-gram AirSource tanks that give hundreds of shots.
In the 1940s, Crosman adapted their pneumatic rifle to use a 4-oz. CO2 tank. In those days, the owner of the gun had to refill his own tanks. This is the collectible compressed gas gun, or just CG.
Airgun enthusiasts have been converting the 1077 to accept a small paintball tank for years. The layout of the gun bears a strong resemblance to the older CG. Crosman borrowed this great idea for their AirSource device.
A magazine within a magazine. The round 12-shot magazine fits into the larger boxy magazine, which then fits into the 1077. This arrangement makes the rifle easy to load and unload. Part of the firing mechanism is inside the magazine, so the rifle's trigger performance will change with each magazine you install. Over time, the mechanism wears in to a smooth double-action pull in all the magazines.
The front sight has a TruGlo fiber-optic tube that gathers light to make sight acquisition fast whenever the light hits it.
The 88-gram AirSource tanks come two to a package and hold a lot more CO2 than the standard 12-gram powerlet. Crosman sets the gun up to work with either one, so you're never far from what you need.
With the rifle comes the standard fill cap that holds one 12-gram powerlet in place. There's also an adapter for the large AirSource tank. At the bottom of the adapter, a valve allows the shooter to shut off the gas supply and take the tank off the gun while still partially filled. Crosman also chose to let the big tank serve as the rifle's forearm, instead of hanging straight down the way the CG rifles and the conversion guns did it.
