Here is yet another fun little doodad from LAPCO Paintball - the Piggyback adapter. This adapter and two bottomlines (duckbills), along with the necessary hardware, will allow you to mount two 7 oz. (or similar diameter) CO2 tanks on your 'Ray.
|The Piggyback adapter is constructed from aluminum, and has two "slots" with pre-drilled holes for two either two-hole or three-hole bottomlines. (Facing the camera is a three-hole bottomline.) In its unaltered form, the adapter will mount two tanks in an over/under configuration to the bottomline block. To mount them side by side, you'll need to drill two holes in the flat area between the bottomlines.|
|The arrows indicate where the two 3/16" holes need to be drilled in the adapter. Be sure they're centered, or the tanks will be crooked.|
|As pictured here, you'll need a bottomline block in your Stingray's grip to mount the Piggyback adapter. You'll also need a couple of fittings and hoses. Various hose configurations are possible. The configuration shown here requires a Dual Adapter, two hoses with AN fittings, two 1/8" NPT male to male AN straight adapters, and one 90 degree adapter.|
|Bottom view. As you can see, I've mounted one bottomline to have the hose adapter on the bottom, and the other on the top. This is to keep the right-hand hose adapter out of the way of your hand when gripping the gun. With the other adapter on top, I was able to use a shorter hose to the dual adapter. With a longer hose, I could have just as easily mounted both adapters on the bottom. You will also need two 90 degree AN adapters and two straight.|
Whether you use the dual adapter or not, you'll need a reducer to attach the hose to the gun.
You can also use the Piggyback adapter to mount the tanks in an over/under configuration. You won't need to drill any holes in the Piggyback to use it this way. Two 10-24 x 3" screws run up through the adapter and both bottomlines into the bottomline block. The fittings I used are a 1/8" NPT branch tee, one 90 degree AN adapter, and three straight AN adapters. I mounted both bottomlines so that the fittings stick out on the left side, to keep the hoses away from my hand when I grip the gun.
One thing I noticed with the side by side mount - the tanks have a tendancy to bang together, making a ringing noise. I simply wrapped electrical tape around the ends of both tanks to eliminate the noise.
