Nerf Gun From Hell

G'day guys,

Last week I went over to my mates place. His little brother is obsessed with the plastic nerf guns and has a sh!t load of them. That afternoon, the 3 of us had a nerf war with the little bro's many guns. After firering all of them, I was very, very dissappointed.

I'm making my bb gun at the momment and because it's all made from screw-in parts, I thought why not make a Nerf Dart attatchment.

At 300psi, I certainly hope this won't be aimed at anyone ;)

The plan should be very straight forward to the pro's but to the noobie's, Give us a buzz if ya want some explanations.

There's a certain fascination with turning relatively harmless projectiles like Nery and airsoft into potentially dangerous missiles :) seeing innocuous 0.12g BBs screaming through stuff at over 1,000 fps always puts a smile on my face :D

Amen to that. I mean the nerf guns are just terrible. They are that weak, that they don't even stick to the walls when fired most of the time. Except knowing me, I reckon now the darts will go THROUGH the wall now hahaha.

in my coaxial, i had a 1/2'' barrel and if you took the pressure over 50psi you would shred the darts when you fired them. i don't think 300psi is possible.

Thats why I'm using a very small chamber. So It's only a short burst of air that pushes them. Like a conventional Nerf Gun.

Looks like it should be a...er.. blast! :D (pun intended!)
The small exit port compared to the barrel size will also reduce flow, which is good for its use :wink:

I have built two nerf guns, and homedepotpro is right, the darts tend to shred in tight barrels. That is why I reccomend a barrel with some clearance around the dart, such as the space between 1/2" sch 40 and a nerf dart tag dart. With my black iron QEV, GGDT calculated that the darts were traveling at 700 fps!

i have had many drat tips fly off using a similar setup to yours and they become very very inaccurate at high velocity's. i have a fully auto Nerf gun (came that way) that would normally be at ~30 psi but with some slight modifications i made it capable of accepting quick disconnect now its running at about 100 and is used to shot "super poppers" (small spherical projectiles which explode with a flash when thrown at something hard, 15 fro a dollar!:P ) it makes the coolest effect.

if you want a great barrel setup use a little 1/2"cpvc at the breech of a 1/2"pvc barrel

1/2"cpvc creates a tight seal on the foam part perfect for pnematics
nerf darts are only thing my pocket 1/2"cpvc pneumatic can shoot with power
also the 1/2"pvc has a good seal for the rubber tip and slevees right over pvc

you would be much better off using a larger chamber at a lower psi. my little brothers modded titan(courtesy of my shop) will draw blood from less than 100 feet. i have several spots on my body that look like someone cut a round hole the size of a nickel in my chest.
