I've been working on clip systems as of late. This is my latest system:
I installed it on the end of the SNAP-1. The white tube is the clip, in-line with the plunger. No modifications were necessary to the SNAP, as it's made out of 1.25" PVC and fittings...it slipped on the end.
This is how it breaks apart for loading. Not as elegant as a clip, perhaps, but effective.
The clip is just PVC. The reason it works is in the 1.25" to .5" endcap reducer (same one as used on the end of the SNAP before.)
The inside surface of the reducer is already curved...I just sanded it so it was flush with the inside of the clip, and curved into the surface of the .5" PVC. I also beveled the .5" PVC as well, and then sanded the entire union...it's smooth, like one contiguous piece. The barrel is 17/32" brass inside of 9/16", sealed at the end with hot glue. The end of the 17/32" in the chamber is flared to the same OD as the 9/16"; it doesn't slide through anymore, and doesn't give any surfaces for the dart to catch on. Dropping a dart into the clip channels it right to the barrel.
After dropping in the leader dart, it's loaded in groups of four:
The current setup allows me to load 13 stefans (I use 1.5" darts). Loading and firing is accomplished by pointing the gun straight down, and pulling back the plunger, then aim and fire. Repeat until depleted. The air pressure of the plunger forces the darts forward, making one chamber and fire. Out of a magazine of 13, I get maybe two or three misfires. (Lubing the clip helps with that) When it happens, just shake the barrel downward, then charge the plunger and fire. I can get off a shot about once every 3 seconds or so.
I may add a foregrip to the clip to give a batter way to hold onto it, and not make it look like an outsize pistol.
