For the nite finder, instead of replacing the barrel with brass, petg, or pcv, could i use copper for the same effect? Because copper ws the only thing i could get a hold of, and it doesn't seem to work.

[six-five-two]

I heard that 1/2" copper is too big for Micros and too small to fit Megas. Just buy some PETG from OMC.

Or CPVC, its pretty good.

[Flaming Hilt]

I can sell you brass at price if you like, since you're kinda new. PETG is cheaper though. Otherwise yea, see if CPVC works; you'll have to bore out the front with a pocket knife or something but it's good for beginners.

I use Cu in air guns sometimes, it's good when you need accuracy but don't want to have extra friction.

Trust me don't get Copper. It doesn't work as well as using 1/2 inch CPVC. I did a CPVC coupler mod on mine and it gets about 65-70". Another reason why you shouldn't get the Copper and get the CPVC is cause the Copper is like 7 bucks while the CPVC is only like 2 bucks.

It depends on your darts. Dart Tag darts fit perfectly in nested brass.

Is there a difference between CPVC and PVC? I tried using PVC but it wouldn't fit in to the Nitefinder when i put it together.

[lionhead333]

PVC is measured by inner diameter, while CPVC is measured by outer diameter.
For instance, most micro stefans are around .48" wide. This fits well in 1/2" CPVC. For 1/2" PVC, you need a dart around .62".
Also, 1/2" CPVC nests perfectly inside 1/2" PVC. This is often helpful for homemades.

No it doesn't. Do your research. Brass telescopes with the next biggest size fitting perfectly over the next smaller. Brass will fit anything. CPVC is smaller. Copper is bigger. PVC is HUGE.

I don't think this is right, because if it were 1/2" PVC would fit micro stefans where in reality it fits mega stefans(made from 5/8" fbr). Also, 1/2" CPVC is about 5/8" in outer diameter, not 1/2". I don't know what their measurements are based on, but its not as you explained.

This is definitely wrong. 1/2" CPVC is just slightly too big to fit inside 1/2" PVC. If you sand the outside of the CPVC or the inside of the PVC then the CPVC will fit in the PVC, but it won't be perfect nesting like how 17/32" brass nests inside 9/16" brass, unless you can sand very precisely.


Raw Shrimp, I would definitely recommend going to some other hardware stores to at least get some 1/2" CPVC. You can also order brass online and PETG from people here at Nerf Haven. It will depend on your darts as to what barrel material works best for your guns. I hear a lot of people say that brass is better than CPVC, but I've tried both and CPVC works slightly better for me. Experimenting with them all is best to figure out what's best for you, but the most cost effective thing is to use CPVC because its the cheapest(about $2 for 5 feet).

[Dayko]

My bad, I put Brass instead of Copper. I'm sorry. I didn't relies until today that I saw what I said.

[lionhead333]

General Cole- I have no idea what you're on about. He asked the difference between PVC and CPVC, and I answered him as near I could understand, with my knowledge of the only barrel materials I have access to.

Derbaron-(Part 1) Since foam is soft, there are often size inconsistancies between batches, perhaps your foam is a different brand than mine. As for PVC, as far as I can tell, there are small inconsistancies in diameter varying by location. Since you are in Texas, and I am in Maryland, we probably are discussing a different processing site. My CPVC's od is .538" (digital caliper)

(Part 2) Again, there must be inconsistancies. My 1/2" CPVC fits exactly into my 1/2" PVC, without any sealant needed. As for nesting brass, I can't compare, as I can't find any near me.
EDIT: My PVC is sch. 40. I don't care i you don't beleive me, I know what my own barrels do. My CPVC fits in perfectly with or without sanding.

How can I make this more clear....

CPVC DOESNT FIT IN PVC IF THEY ARE OF THE SAME SIZE

If there really are regional variances in PVC sizing, I can't understand why. It could cause plumbers that move from state to state to mess up plumbing projects. Has anyone else come across 1/2" CPVC that fits in 1/2" PVC?

I'm well aware of the batch inconsistencies with fbr, but I don't think I was objecting to any claims about fbr sizes. If you were referring to how I said CPVC works best for me, I know that is because of differences in my foam versus others foam, which is why I would suggest that everyone do as much experimenting with barrel materials as they can instead of just accepting what others say.

[Belgianwaffle]

My 1/2 in. stefans fit good in my 1/2 in. copper. But now I'm starting to use aluminum because it is so light.

[monkey with a nf]

I'm pretty sure that 1/2" CPVC doesn't fit in 1/2" Sch. 40 PVC, but it might in a lower schedule (though I've never seen it anywhere, even McMaster-Carr).

[wintermute]

don't knock copper, 1/2'' works great with my 1/2'' stefans

[Steveep]

First, my opinion on copper. My stefans will fall out of copper pipe, BUT, they seal surprisingly well, and have very low friction. I use a short piece of 1/2" cpvc, followed by a long piece of 1/2" copper. copper repair tubing makes a great joint between the two. I used this method on my big blast, which gets over 100' ranges easily. you are best using a breach system, since the stefans have a hard time going into the cpvc if you are muzzleloading.

As for pvc and cpvc sizes: they come in shedule 40 and schedule 80, which are slightly different in size. the pvc and cpvc I use fit loosely inside each other. If you two are using different sizes of pvc and cpvc, you would probably get different results. so please stop arguing about it. use whatever works for you.

[frost vectron]

PVC! Bah.

First, sizes that don't make any sense--now regional size differences? This is getting out of hand! I know that when I buy 1/2" CPVC, some lengths are very tight on my stefans while others are very loose on them. I figure that's just a small error when they are produced. I had not imagined such a consistency error that will let 1/2" CPVC fit into 1/2" PVC. That is a golden size! Breeches must be incredibly easy to build for you
