This topic is to point out what barrel materials usually used for modding nerf guns.

If you are new to the art of barrel replacements read this article by Cxwq. It should answer most of your questions and is a good starting place.

If you have further comments on or links to barrel modifications this is the place to post them. The idea is to have one place to answer questions on the subject without making new and redundant topics we've read more times than we care to.

How does adding a PVC coupler to the end of an air chamber make it breech loading? is there a slit in the side of it or something?

Well, the coupler allows you to pull the barrel off, put the dart in, and put the barrel back one. This allows you to reload without having to ramrod the dart in. That's how it works.

If anyone would post what sizes of PVC and brass they recommend for micro stock and micro stefans, I'd be eternally grateful of them / willing to donate blood to them / appreciative.

I thought it'd be 1/2" for the CPVC and a bit more for the brass, but nothing fit my darts.

I know this is an old topic but i didn't want to start a hole nother topic for just one question, any way.

I was just wondering why copper dosn't work good for a barrel. I've all ready heard the story about copper is the stuff that comes from inbettween your grandpas legs but other than that i really don't know.

I'm going to just pretend that I didn't read the last sentence...

Use the barrel material that fits your darts. Period.

If you're using stock micros, 1/2" SCH40 PVC fits the tips nicely and 9/16" OD K&S brass or crayola markers or .55" ID PETG will do for the body.

If you're using stefans, nothing I say will help you because your foam isn't the same size as mine. Take a piece of FBR to the hardware store and start hunting. Then take it to the hobby store and do the same. Chances are you'll find something that works.

I would recomend the use of hollowed out crayola markers inside a length of 1/2" SCH40 PVC for guns that use stock micros.

It's clear, lighter, easier to cut and can be ordered in sizes that more exactly fit your foam backer rod. Generally however finding it requires you to custom order it or get some from someone who has, were as PVC and CPVC can be had at most any hardware store.
Because you can match it to your FBR that you use for stephans allows superior performance in valve based guns where you want a perfect fit rather than the tight one you want for a spring gun.

Ive used that on my AT2k, LBB and NF. Works great with matchsticks too.

I've got a question. If you replaced a spring in, say a Big Bad Bow, would you need a longer barrel than normal to compensate for the plunger's accelerated speed? Would the same concept apply to pump guns as well, swichting from a ballvalve to a sprinker valve because the air is also moving faster? And shouldn't nested brass barrels always be used in spring guns as opposed CPVC?

I've got another question. I just ordered some 0.5" ID PETG from McMaster and realized that its ID is too small for my darts. My question is; Can I use a 9/16 drill bit to widen the ID on the PETG even though it will leave 1/16 of space with its 5/8 ID? If not is there any other way to evenly widen it?

(Sorry for the double post)

That's what I'm thinking.....

If you can find a 9/16 drill bit, LET ME KNOW!

But yes, I believe you can.

Thanks nerfer34. I found several 9/16 drill bits at Lowes and Home Depot and combined with the bit extensions, I should be able to drill all the way through the barrel.
