FAQ: Foam Gun Spring / Oring / Etc

Adapted from Nerf Haven:

 

This is a common misconception among new players

 

LONGER BARREL = GREATER VELOCITY (to a point)

GREATER VELOCITY = BETTER RANGE (universally)

 

Once a dart leaves the barrel, it stops accelerating and starts slowing down due to air friction (drag). If there is enough air pressure in the barrel for a net positive force on the dart, the dart is accelerating while it is in the barrel.

 

So if you can maintain that air pressure, and make the barrel longer, the dart will have more time to accelerate (increase speed) before it leaves the barrel, and will leave the barrel with a greater velocity.

 

There is a point where, as the dart moves down the barrel and the pressurized air expands to fill that space, the force applied to the dart by that expanding gas will be overcome by the frictional force of the barrel, and the dart will start to slow back down again.

 

However, because of the high friction and low mass in most dart/barrel combination, the margin between the barrel lengths where the dart will begin to slow down and the length where it will come to a complete stop in the barrel is relatively short. So you'll probably know it when you see it happen.

 

As far as velocity vs range, it is a basic fact of physics that the distance a dart will travel is a function of it's velocity when it leaves the barrel (muzzle velocity).

 

If you're using the same darts, you can't increase the muzzle velocity without increasing the range, and vice versa.

 

You can increase the range of a dart without increasing the initial velocity by reducing drag (air friction) but this is a property of the dart itself and has nothing to do with the barrel.

 

So it's impossible to have a gun with 'good velocity but crappy range'. Unfortunately a lot of people seem get that wrong.

 

Note: The 'barrels' on most of blasters are probably just for show, and seem slow the dart down in most cases.

Note if you are clueless about science / physics or the "I hate science type".
Stay off from this subject and continue to play your MMOs and FPS online.
The limitations of Science / Physics applies to the real world, not the Cyber Games.

So basically... Barrels must be long enough to allow acceleration of darts but short enough that the dart doesn't start decelerating coz of friction of dart and barrel?

[Toys_god_of_War]

Heh Heh.....that is physics for you.
Ask a teacher to explain for more details.

The idea not to discourage new players but to work within the confines of scientific rules, instead blabbing reflexively.

I am very interested in your custom 12dart magazine. However I use a half-pipe brass breeched Longshot which would be destroyed by this magazine, plus S$50 is a steep price to pay considering I want 6 of these. Is there any possibility of making a plastic version of this (basically a normal Nerf mag but with 12dart capacity).

[randomtrader....]

Is there any reason why it would be destroyed?

To load a clip into a half-pipe brass breeched longshot, you need to jam it over the brass when the breech is closed. The stock nerf mags allow for this because they're plastic, non abrasive, and flexible.

An aluminium mag isn't as flexible and is very likely to scratch (and possibly mangle) the brass due to the force you need use to push the clip in place.

There is no plastic 12 dart magazine

What else can the 1911 foam dart gun be modded apart from the harder spring?

[staromega]

in term of performance?  nothing.

If you wanna mod further, go ahead.

If you are successful, let us know.

If you bungled, let us know.

Most impt of all, wear safety gears when trying.

[Toys_god_of_War]

BTW even prominent nerfers like "jerm" of Nerfornothing worry on overloading his nerfs and cracking them with powerful spring.

well u can make them yourself by getting 2 6 round clip and modding it..youtube got alot of this videos
