OK, right now, I am more determined than ever to make a full automatic nerf gun. or at least one that repeats. Anyway, please post your ideas on the subject here. The only way I can think of is to use co2 and I don't want to without a regulator (expensive and bulky). So, since this is a brainstorming thread, lets brainstorm.

Attention everyone, I am proud to anounce that my testing is complete and I have developed the first working nerf shotgun. It's muzzle load which is the only bad thing but with 5 pumps I can shoot 10 darts 20-30 feet (I haven't measuerd so its around that distance). I have a small problem with a leak around the pump and after thats fixed the "Longinus Gun" will make its first appearance on the internet.

I've got an idea on firing using CO2.

Basicly, this is an idea i got while looking at a Tompson sub-mechine gun (tommy gun). I dont know alot about CO2... so this is just a guess.

Picture here

The Black thing that kinda looks like a CO2 tank is a. . . .You guessed it! A co2 tank!

In back of it is a spring

In front of it is a bar going throgh the PVC. Attached to it is a rod/pole.

Then some fittings to reduce the size of the PVC down to 1/2".

Next is two 90* 1/2" elbows.

Then comes the barrle, with some kinda magazine on top of it.

I'm not sure how the mag will work. . .  this is just my idea about firing repeted shots of CO2.

---

What happens is the CO2 tank is pushed forward by the spring. The Rod/pole presses the pin on the CO2 tank releasing the CO2. The CO2 travels throgh the elbows to the barrel and launches the dart. The force of the CO2 being released blows the tank back and compreses the spring then to whole cycle starts over again.

It's just an idea...
What do you think?

I thought this was a rather good concept. I'm going to try to make something similar and I'd like your feedback as to whether you think it'll work or blowup in my face. I'm hoping mine will have a large gravity feed clip and the CO2 cartriage wil be held within 2 1/2 different chambers. One inside another insde a partiale cover. I hope to get my blueprints up soon.
Mine will also have a trigger.
