Ya know... I sent off for one of those kits. They cashed the check and never mailed the darn thing. When I called about it, a nice little old lady who had never even heard about paintball answered.
As for a break-down shot:
If you look near the top of the feed neck, you'll notice two little holes. They are threaded! In a time when feeder elbows were normally held in place with electrical tape, the guys at CASL used a screw! Drill a little hole in your elbow, put it on the neck, put the screw in place, and WHAMO! no more lost hoppers!
