I modded my NF tonight and did the crayola barrel with pvc over it to stabilize it. The total length of the barrel is about 5 inches from tip of the marker to the end of the overlaying pvc. I'm only getting about 40' which I can do better with the stock version witht the pole removed. People had said the mod should give me around 60'. Is the barrel too long? is something done wrong?

I wouldn't use a crayola barrel. Go pick up some brass or something. It could also be
Did you drill a hole in the air restrictor? If you didn't you should, it gives the NF a pretty good kick.

I took out both air restrictors but this mod is supposedly supposed to give it a good range, I was just wondering if my barrel was too long of if someone who did that mod could point out something I did wrong or didn't do at all. Crayola is just a temporary solution because no place in Ottawa sells brass piping so I'm waiting on either BW to email me back or I find a good place on the net that ships to Canada.

I'd check the seals on the barrel.

Spring guns rely heavily on the dart fit. What works for one person will be shit for another, all because of a 1/32" difference in FBR size.

Personally I'd do a nested brass mod because you can find two adjacent sizes of brass which fit tightly/perfectly for any size FBR.

I have also found out that my spring (the new EX-3 version) is too weak. I've called every hardware store in the city ( including Home hardware, Rona and Home Depot) and they all carry springs but they are too small. I picked up one for a screen door kit but it was WAY too powerful. Does anyone know a good place where I might find one, preferably NOT online.

When I had PVC over my Crayola it shot like shit. I just have a Crayola now and I get about 60'.

How was the spring too powerful? Isn't that a good thing?

Unless you live in the middle of the desert you should have plenty of stores that carry springs of all sizes. I got my spring for my NF at True Value Hardware, so if you have one of those near you try there. It shouldn't be a problem, every hardware store I've been to has springs, I don't see what you mean that they are too small. Just go to your nearest one and look for them rather than calling.

Also aren't most screen door springs stretch rather than compression springs?

Not if you can't cock the gun, or firing it would cause it to break.

They were too small because they wouldn't fit over the plunger and they were only like 2" long.

There is too springs on the screen doors, one that stretches and pulls which compresses a compression spring.

And no. There is no True Value in Ottawa :(

If you'd like, I could pick up some of the springs I have and mail them to you.

I agree. I've been brainstorming an idea for possibly having multiple inserts on barrels so that you can properly size a dart to the barrel. I haven't done size testing on spring guns yet, but for my new single barreled AT2k, my idea is that if you can slide the dart in the barrel so it gets stuck and are able to blow it out still, that should be the perfect size barrel. Again, this is all peliminary, when I get a little more time I'll try it out on my Crossbow.
