NF Coupler Mod

Materials: 1 NF, 1 1/2" CPVC coupler, about 4.5" of 1/2" CPVC, electrical tape, Dremel, drill, 3/8" bit, lots of hot glue, epoxy or Plumber's Goop.

Procedure

1. Take apart the NF. You shouldn't need a picture for this one.

2. Take out the plunger tube, take out the whole barrel assembly and toss it (unless you want it) and take out the small cap like thing in the end of the plunger tube, take your drill and 3/8" bit (anything will do actually) and put a hole through the "X" on the cap. You're going to need to Super Glue it (or epoxy, any kind of extremely strong glue) back into the end of the plunger tube, as we'll be putting a LOT of stress on it. It doesn't matter which side of the cap is facing out, they're basically the same.

3. Take out your plunger and take off the o-ring on the plunger head and wrap as many layers of electrical tape around it, until it fits very snugly in the tube and you know there's no air getting out.

Here's the plunger wrapped in tape:



4. Take out your coupler and glue it on the plunger cap thing as good as you can. Use massive amounts of whatever you're using because this is hard to get to stay on. You might want to wrap it in e-tape when you're done gluing/epoxying/Gooping. Now add your CPVC barrel in the coupler. Don't glue it because the whole point of this mod is for changable barrels.

Here's the barrel assembly:



5. Now we need to Dremel out the case. I used one of those little sander type things and just went right in where the stock barrel used to sit up against (I'd already done a minimization on mine) and shaved it down...way down. But NOT so much that the coupler fits easily, we want the opposite, so that it doesn't move.

You have to look close, but you can tell it's been Dremeled:



6. Reassemble it! I don't think you need a picture for this either. Careful with the screw ports on the plunger tube though, mine all snapped and now the whole tube shifts whenever I fire or load the gun. Make sure you add a few bands to it so that the plunger can move through the tube - with all the tape on there it may not work right.

Range: 60-65' flat average, sometimes spikes over 70'
Accuracy: Excellent (can consistently hit a Tide bottle from 30' one-handed)
ROF: Good

I love this gun. The accuracy is superb, range is better than any other pistol I've got and the feel of it is just amazing. I've produced about ten barrels to date, which is plenty. I love to pop the barrel in and out and the beautiful noise the gun makes when I fire.

Oh, and I'm sorry for the garbage pictures; Sqiggs took those for me while he was over here with his cheapy little camera.

Hope you like it!

Thats cool, though I thought I remember seeing this mod somewhere. Anyways, I was curious if it would wark to put an at2k barrel on the front of a nf. But I bet it would lose a lot of air and probably wouldn't go far. Just a thought.

Here? That would be my clan's webpage (if you can even call it that), and I posted it on the Quilted Northern forums, but if you've seen it somewhere else please tell me where.

NerfMonkey is officially mod king.

Oh, and l actually have a question. I have a little stick of 1/2" CPVC, you see, and brought home a couple of 1/2" Couplers from the shop. Before I mod this (suprisingly, I've never done a coupler mod), I want to make sure it's the right size. The problem: it felt a little lose (not tight like I think it's supposed to be). Do I have to go back to the shop to get a different brand, or once I complete the mod will it all work out well?

How are the ranges on the gun?

Edit:sorry...I didn't see that you already listed them

I don't know about CPVC, because I've actually never bought CPVC couplers. But as far as all kinds of PVC goes, the couplings should be tight. VERY tight. So something sounds wrong here. You might want to make sure you got the right couplers, because I have all kinds of different brands of couplers for 1/2" PVC (for example) and they all fit the same.

That's a very solid mod. It would be nice to have a pic of the finished product though...for some reason, that just makes it complete in my mind. I have a CPVC barreled NF that gets no where near those ranges, but I think that it's because my Stefans are a bad fit for CPVC...I've since then stopped using it.

[NerfMonkey]

The barrels are tight enough in the coupler that the barrel makes a seal and range isn't compromised; they're loose enough that the barrel comes out easily.

I'll try to get a picture of the finished gun (actually another gun because I painted it) by tomorrow. If not then, two days.

EDIT: Sorry chris, didn't see the rest of your post...if you have CPVC and CPVC couplers, they should go in airtight, but you should still be able to twist them out again - the barrels, that is. If you could get a picture of the couplers and barrel I could help you more, but just make sure you have 1/2" CPVC couplers for your 1/2" CPVC obviously.

This is a fantastic mod! I like it for the sytle. The range on my other NF was about the same. I can believe the ranges because I get them. I have a diferent type of coupler than NM and I think Mines a little easier to use. But mine were like $.11 more expensive.
My gun gets the following ranges (Single banded, with three different ypes of darts);

1st. dart (A 1/2in Stefan that is a little smaller than ture 1/2in FBR)
Range: 55' flat. 60' Angled

2nd dart ( A 1/2 Stefan that is very nice fit)
65-70' flat. ? Angled, I can't find the dart.

3rd dart (A loser dart with a SlingShot ball as a weight)
60-65' flat. 85-90' angled.

This is done of course with one band and wraped plunger head and done with a different coupler. Get's the same range if not better. I'll test again and keep you posted. If you don't believe me than sorry but I don't need to prove anything anyway. It's not like I have to say "My gnu gets' like 100'" I'm honest about my ranges because what would I be trying to prove...? Excactly. I just Mod Nerf and give the proper ranges my gun gets.

Uh...okay then.

I'd like to see these couplers of yours, and where did you get them? I'd like to try them. Glad you finally couplered your NF.

Thanks for all the comments guys! More mods to come, including my Monoblast mod and possibly another special treat.
