Rebarreling a NiteFinder

Currently my NF has the air restrictors taken out. Hole drilled in the plastic cap which had the barrel post. Multiple rubber bands added as well. No reinforcements or spring replacement. It is more powerful now and is quite loud. However it is inaccurate. How should I fix this problem? Should I replace the barrel with a longer one?
I've seen Roger Explosion's brass mod but what does it really do? Does it just make it more powerful? And how do you get the dart to go all the way in? Wouldn't it be impractical to use a ramrod?

Im testing with streamline darts. One of the darts has glue in it. Usually when i fire the streamline darts it defies gravity and goes up first and then wildly left and right. Would replacing the barrel make it more accurate?

Rebarreling it helps with range and accuracy.



I was testing this one before with a couple of "Postie" bands on it. firing Tag darts and my converted darts and i was able to hit a bedside table easly from bout 15 meters away. So putting a brass barrel on it makes it much more accurate.

I didn't notice much diffrence between ramroding and just pusing the dart in with my finger. there is only noticable range diffrence with high power guns like a Big blast or my Big Bad Bow.

But there is another solution, which is to add a coupler. like Ham Sandwich here


So you can pull the barrel off and stick the dart in the back of the barrel and put it back onto the coupler. which is faster and eaiser to do than ramrodding. especialy if you have multiple barrels glued together (AKA Speedloader)

I thought the Tagger darts had a massive head on them. So they fit in the tight barrel. So you put your finger down the brass tubing to push the dart all they way in. I dont even know if my finger is long enough or skinny. My left index finger is only as long as your brass barrel in the picture! My finger is 6 cm. And finger width is the size of a streamline dart. So im kind of puzzled.

I did make that a little confusing. I was talking about not ramroding the darts all the way in. just still having the heads sticking out the top. There is no way i can fit my finger down that barrel. When they are loaded in like this there is a bit of dead space in the barrel behind the dart.

So if there is space behind the dart will the darts still be accurate? Im thinking about using PETG or CPVC. What is a good length? I will be using streamline darts mostly.
Im am thinking of getting the MOD MAN PETG. What is the difference between the thick walled and thin walled? The main reason i am rebarreling is to increase accuracy because currently it is too powerful. Does anyone sell PETG or CPVC here?

Its still as accurate with a bit of dead space, you may just loose a foot or two in range. 4 Inches should be good barrel length. If you're using Streamlines you can still ram rod it down the whole way. You just need to make sure there is something at the end of the barrell to stop the dart from getting into the plunger.

So im going to need 4 inches long, 1/2 width, thick walled PETG which i will rebarrel my NF to increase accuracy.
Thanks Roger!

Would the dead air mean the NF dryfiring? Unless you put the dart to the end wouldntit be dryfiring?

There is still a seal with the dart in, so It wouldn't be dry firing.

I am going to refer to your brass barrel mod Roger.
What pieces of the stock barrel did you throw out? I saw that you cut some of to fit the brass. Your new barrel, was it placed ON the plunger or IN the plunger tube? Does it really matter? How far in should the new barrel go in the plunger tube? I presuming it is a little bit in to keep the barrel stable.

Thank you for your help

What does this do?


Why do people drill the middle bit out?


Is that an air restrictor? Because i didnt drill it out.

This is in a NF by the way.

Its what the Plunger head stops on. It also makes up part of the air restrictor. Having it like the second picture will help increase air flow.

If that is where the plunger stops then when people drill it out, where does the plunger stop? Wont the plunger slowly be worn away and in the end break?

Another Question. At what time of modding does dryfiring becomes an issue? Is it when you take out the barrel post, drill a hole in the air restrictor or take out the spring and three pong plastic?

As soon as the Air Restrictor is out, you better avoid dry firing.
With the AR in, it will create a cusihon of air to slow the plunger. But when its gone, The Plunger head will hit the end at full force. When there is a dart loaded there will be a build up of air which will slow the plunger head.

As for the other question

The Plunger head still stops on the outer ring part. And I've had no problems with plunger heads breaking with that part out. I don't even think the middle part of that plunger stop piece even comes in contact with the Plunger head. I think it is only what holds the spring for the 3 pronged part of the Air Restrictor.

Oh man. That sucks. Now I wont take out the AR's in my Recon or Maverick. I dryfire accidently a fair bit.


So if I put my finger in the barrel of a modded NF. And I fire, it doesnt mean I dryfire because the finger is there to build up pressure.

As long as you make a good seal.

I just finished modding my nightfinder replaced he barrel with pvc it is fantastic I recomend doing this.
