It does about the same thing as before. Makes a loud bang.

Make sure your system is gas tight. I have gotten about 40 feet out of a dart propelled by a cap. Also, make sure the barrel is not any longer than it needs to be (hardly longer than the dart in my experience)

Just make sure not to give away your position prematurely. :D

This is interesting though, I never have even thought about a cap gun converted to nerf... I know even though it's minimal (you can put your hand in front of the barrel), it still releases heat, which I thought would acually burn the ends of the darts you fire. I think you may be better off with a looser barrel material though, since if I'm thinking right, the heat would expand the dart momentarily, as well as the dart expanding normally from the pressure of the air being released to fire it.

I've made small nerf blasters from the champagne bottle confetti poppers that shoot 20 or so feet. All I did is take out the confetti and crudely e-tape a peice of cpvc in. Its definitely possible, I just recommend you use something with a little more "oomph", like using match heads for a propellant instead.

Its not shooting because the gas escaping through the hammer gap. it would be very tough to get it completely airtight.

Instead of making a cap gun fire nerf darts, I've tried using a confetti popper gun such as this. (Except mine was single shot, but fired the same type of shells.)



The green cylinder in the video has six tight shells that has a single ring cap placed at the back. They can fit 1.5" stefans (I used CDTD's) and fire them up to at least 40'.

After I tried this out, I was amazed that it actually worked! When I went to go retrieve the dart, however, I found it burnt at the back. The whole experience was fun nonetheless. :D

I live in Canada and the only place I know that carries that type of confetti popper gun is Gags and Giggles. You might find it in a dollar store though, which is where I found my single shot "popper".

All I'm saying is that confetti poppers are more practical to use than cap guns when it comes to converting them to shoot Nerf darts, from my experience.

I have been trying to find an online source for those. When you look at the back of the cylinders, is there a hole between each "cap hole" that is blocked by the piece of plastic that links each cap together?

Flashflint: In the back of each shell, there's a tiny cylinder about .5 cm tall and .3 cm in diameter. Inside the tiny cylinder is what you would normally find in a ring cap gun, where there is a little nub for the cap to rest on with spokes connecting the nub to the shell.
(Click on the link near the bottom)

When the hammer strikes the cap, the "gas" passes through the spokes propelling the dart foward. Also, there's a tight seal where the cap rests, so none of the "gas" will escape. The only drawback about this is that it's hard to remove the cap after firing.

The confetti gun fires six rounds, but the standard ring cap consists of eight caps, meaning you will have to cut the caps individually for each shell. Funny thing is, if you watch the video closely, the guy at the end fires seven rounds. Strange, eh?

PS: While researching more about the six shot confetti gun, I found my original one online. I remember I put a spring underneath where the shell is placed, so when I open the breech, it ejects! I donated it to Value Village awhile ago though.

Edit: I just remembered a way to make ring caps more powerful...and also louder. Take a roll of paper caps and cut them to fit into the ring caps. I've tried it before and it is definately louder, but I haven't tested it to fire nerf darts. Instead I did this for my BB cap gun I converted. I should warn you though, it's a tedious task.

I am aware of the tediousness, I have experimented with it quite a bit before. Thanks for the info!
