I recently bought a RF20 from TRU, and I was just got the idea to single barrel it. I thought it would be a good loser with a long barrel, since it releases so much air. Any comments?

[NerfManiac]

A nice idea in theory but....

The RF20 has a piston which evenly distributes that "large amount of air" over a period of 20 shots. No-one that I know of has successfully gotten rid of the piston and still had a working gun.

The rf20 is meant to be an automatic. Don't change it.

How ever, You could have it single barreled and only pump it once or twice a war.

[Langley]

Look, if you want the same effect get one of the newer super soakers and pull the ruber bladder out and modify that. It's essentially the same thing, except you won't be gutting one of the most fun nerf guns you can carry into battle.

Edit: If you do single barrel mod it, I'll buy the barell assembly off you. I want to see if I can convert it to be a clip.

[Ice Nine]

I haven't opened it yet, so I dunno exactly what I'm gonna do. However, if I do single barrel it, Langley, you can buy the barrel assembely.

[Alexthebeast]

Don't sell it, use it as a stefan rack for drying while you are making them, that's what I do.

[Jangadance]

Stefan-Rack? Is that a variety of Man-tits?

You'd be better off using pieces of CPVC, don't you think? You'd be better off giving it to the Langley.

[Alexthebeast]

I'll keep mine. it's not like I singled it, I just dont use it so I "borrowed" the turret from my rf20.

[Black Scout]

I don't see the point in making the rf20 a single barreled gun. The purpose of that gun is for assault from close range using a barrage of darts. Instead of single barreling it, just use a super soaker.

[Exis]

I have successfully created an interchangeable clip RF20. It does reduce the range somewhat, but I have been working on another version in which the inner ring of barrels are brass-modded. It actually works!

[Jangadance]

Sounds great, Exis! Start a new thread and post your procedures and results. I'd love to hear this, since I have 3 WFs and 3 RFs respectively...

[Langley]

That's not how you use "respectively"

[Jangadance]

respectively (adv): in the order given; "the brothers were called Felix and Max, respectively" from dictionary.reference.com


Are you positive?

I've actually single barreled a Power Clip once, and I don't recommend it. The problem with single barreling an automatic nerf gun is that while the volume of air released is high, the pressure is not enough to make it an effective loser weapon.
I also tried to correct this by reducing the size or the air bladder to no real improvement.

The problem is that unlike other air presure guns, the nerf automatics are designed to let out a sustained and constant air flow, not a single high pressure blast.

So keep your Rapid Fire 20 as it is, you'll be happier that way.

[Ice Nine]

You have some good points. But if I think I know my stuff...Then a singled RF20 would work like a super soaker. Both are designed to throw out a lot of air for a long period of time. Hence, a long barell.
This is only what I think, and I think I might be right.

Well good, that makes one of us.

Here is why you are mistaken, I don't mean to rip into you I'm just providing a detailed explaination.

The thing with Super Soakers is like a most nerf air pressure guns the air chambers are made of a hard plastic, not rubber like the RF 20. This allows the pressure to build up to a high level because the volume is constant. With the Nerf automatics the air chamber increases in volume as air is added, thus the pressure does not build up as much.

The reason for a long barrel is not because just because of the volume of air. The longer lenght allows a dart to accelerate over a greater period of time as it travels down the barrel. The length of the barrel is limited by the volume of air, if you put a long barrel on a LnL (a lower air volume gun), it won't work becaue eventually as the dart travels the air pressure will decrese as the volume of the barrel behind the dart approches that of the volume of air behind the dart. Air pressure decreases as the volume increases.
Pressure also determines velocity. A gun with a low air pressue, regardless of volume will not propell a dart very quickly.

The advantage of converted super soakers is that you can pump a lot of air into them and thus as darts travel out the barrel the air pressure remains higher longer.
However you do have to pump them up a lot in order to create a high enough pressure to attain a high velocity.

The RF20 has the ability to send a high volume or air out a single barrel, but not at a high pressure, thus velocity is going to be very limited.

In conclusion: Super soakers have high air pressure and a high air volume while the line of automatic nerf guns have lower air pressure and a low air volume.

Now if you want to go ahead and try it despite what I've said here are things I would try.
1) Add rubber bands around the rubber air bladder on the RF20.
2) Remove the air release at the end of the air bladder so you can pump more air into the bladder after it has expanded to it's limit.
3) plug the air release on the pump handle.
4) Good luck

[Ice Nine]

Well good, that makes one of us.

Meh. I don't really know my stuff that well...make that none of us.

I may just go out and buy another one, and for the hell of it, try to single it.

[Ares]

NO!!!!!!! No SINGLE! It's a geniously designed piston operated automatic! YOU DONT SINGLE BARREL! Why is it people make mutlibarreled guns single, and single barreled guns multibarreled? I jsut don't get it. It's an automatic. Leave it.

[Blaster]

i think you should think this through a little more. the whole point of the rapid fire 20 is to fire twenty darts in rapid succession (hence the name). anyway my point being that why buy a great gun and then totally change it's purpose. you're probably better off buying the super soaker and then modding that. If you think about it that way you don't kill an awesome gun on accident and if you screw up you can always buy another supersoaker and try again because basically all super soakers rapidly shoot out air. with a supersoaker you dont need an a full auto or a semi auto because it always shoots in rapid succession. with the rapid fire you get a great nerf gun that shoots a whole lot of nerf darts in rapid succession and those are a bit harder to get than a supersoaker. (at least where i live).

[Ice Nine]

Look, Blaster, I opened up my RF20 a while ago, and since I did need a multi-shot gun, I just took out the barrel pegs. I got it November, and opened it up in early December. If you looked carefully, I had another topic discussing a problem I had with the rotation mecanism and it wouldn't fire. Before you bring back an old topic, be sure it hasn't already been attended to.

[Spoon]

Besides, the "it's fine the way it is" attitude isn't really the most condusive to modding in the first place.

[Blaster]

i see. but the point i was trying to make was that it would be kind of pointless to switch around the guns purpose entirely. i'm not saying the gun is "fine the way it is" because there's room for modding in just about every gun. Sorry if it seems like that was the direction i was going in. But since we're on this topic did you manage to get the gun out of single fire?
