I will have the ranges tonight or early tomorrow. Do i really need to test the stock suction darts and the stock rockets? They suck horribly and only go 30-45 feet. Also, anyone have an idea of how to keep my CPVC barrel leveled? My tape isn't to strong and it jiggles around. Thanks

Well, what did you do to it? If you cut the stock barrel completely off, you're probably going to have to get some epoxy to gluethe CPVC on. And/or, you could do this:
http://thefoamfighters.smfforfree.com/topic/158.0.html with FBR
or this: http://nerfhaven.com/mods/haze_bb/ with wood.

If you have at least an inch or two of stock barrel left, here's a trick that I figured out. It may not be the best, but it works and the barrel seems straight. Plus, it's all easily reversible if you don't like it.

1. Get some 1/2" CPVC and PVC, a  1/2" CPVC coupler, and a 1/2" PVC coupler

2. Cut a 1" to 1.5" (can't remember, might even be longer) piece of PVC, then put it in your coupler. This piece of PVC needs to go all the way in, until it hits the little ledge inside the coupler. You may need a mallet to get it all the way in. (You may also want to cement that together with PVC cement or epoxy, but I didn't).

3. Now dremel sand down the inside of that piece of PVC that you just put in the coupler so that it just barrely fits on the end of your stock barrel. Note that it needs to be a tight fit. (you may want to epoxy this on, but I didn't). Oh, you want your barrel to be able to go all the way through the PVC (i.e. not just the first fraction of an inch)

4. Now, now take the CPVC coupler and stick it in the opposite side of the coupler (the side that has no PVC in it). Again, use a mallet to make sure that you get a good, tight fit. Now, slide the whole thing onto the stock barrel until it stops (it should hit against the CPVC coupler).

5. Make a barrel of desired length out of CPVC, and put it in the CPVC coupler. And that's pretty much it. You now have a CPVC, couplered barrel. Also, the coupler can come off the stock barrel if you want to change something (unless if you epoxy it on).

Of course, the couplered barrel also makes it breech loading. Because I didn't cut my stock barrel off at all, I actually drop my stefan into the stock barrel, then attach the CPVC barrel onto the end. I didn't measure ranges, by the way, but it seemed a little shorter than what I've heard sometimes. Of course, it was raining and I think my barrel's a little short.

Thanks, I was doing ranges after school today but my gun started to mess up. I pumped it 20 times, loaded the dart, pushed it down into the CPVC, and then shot it. With a Stefan i only got around 75' with it at my shoulder ( I'm about 6'0" at the shoulder). The darts after that one started to spiral out of control and dived very quickly. The stock rockets barely went 15 feet too. Anyone know whats wrong with this? I think it could be my barrel because it isn't completely leveled but then again, i could be wrong. Thanks

Edit: Would a Crayola barrel in this case help at all? Thanks

Crayolas are mainly used to put inside of PVC, or are just used alone. I don't think they would help you here.

It could be that your dart isn't fitting right (either too loose or too tight), or your barrel might be too long.

Or it could just be an unstraight barrel.

Yes, my barrel is all over the place, the only thing holding it together is electrical tape and scotch tape. I'm using the normal micro dart FBR, forgot the size, but it fits fine in my Nite Finder and fit fine without the barrel. The barrel is about 1 foot long not counting the stock barrel. Would that be to long? Last question, do you know why my darts would be whirling around like that? I hate asking a lot of questions, sorry.

Well I suppose the whiling could just be the wind, or you may not have enough weight. Speaking of which, insufficient weight (I think) can have a negative effect on range. Try adding a slightly larger weight, or even put in two of whatever you're using. Or your weights are off center.

I believe that it is 1/2" FBR, but there seems to be a fairly wide variation within that range. One person's FBR may be way more than 1/2" another might be just perfect, another might be even smaller, so who knows.

The Nerfhaven mod by the Haze uses 14-16 inches of 9/16" brass and got 100 feet, pump not plugged. Your barrel is longer than that, it would seem. Are you pushing the dart all the way to the back of the stock barrel? Because you should, or else cut that thing down. You don't want too much "dead space" between dart and air output.

Also, barrels for springers should be tighter than barrels for compressed air guns. If it worked for your NF, it may not work for your LBB. Try heating a 1 foot length of FBR with a hair dryer while stretching it. Do this until the FBR looks like it will just barely have some friction on the CPVC, then make a few stefans and try those. (note the ends will stay thicker than the middle)

I don't know if i am pushing it down all the way or not, i got a pretty long plastic stick that fits far down. What would you recommended that i do? Should i just replace the entire barrel, i have like another 20 feet of the CPVC. Or, should i keep fiddling with it until it works. Thanks for your help

To see if it's all the way down:

1. Place dart in barrel and ram down until it stops

2. Mark line on ramrod, level with barrel's end

3. Take ramrod out and place along outside of barrel, with mark even with barrel end.

If the plastic rod reaches within one dart's length from the back end of the barrel (give or take a half inch maybe) it's probably all the way back.

I don't know what to tell you otherwise. I will say that, if you do replace the whole barrel, make sure that you don't accidentally plug up the air output with epoxy or something.

I would have had ranges today, but the wind is going crazy and in every direction. So, instead I will show you how to put a barrel on the LBB. Go out, and buy some 1/2" CPVC. I got my CPVC for like about 4 bucks or a giant tube, also grab some electrical tape and a 1/2" PVC coupler. If the store has a 1/2" CPVC coupler I would rather get that because then you can skip the tape and just put it together. So,  its pretty easy to put together. Just wrap electrical tape around the barrel until it because extremely snug inside the coupler. I didn't count because i was watching Star Wars. Also,  you may need to hammer the CPVC in so it because very tight. I guess you could wrap the tape in the same amount, around the stock barrel, but if you have huge hands like myself, it is a whole lot easier to just take it apart and wrap it around. So, all you need to do is wrap electrical tape until it becomes snug. I don't have any brass and don't know how that would work.


Sorry for the paint image and no ranges yet. My camera isn't working and the weather has been too windy.
Average ranges are about 100 feet or more. I don't know about my mod yet though.

Cool, I get what you mean. I accidentally made the same mistake and discovery about the coupler. I got 3 though so now I have no excuse not to do this mod(Except laziness)

Going outside to do the range test, sorry for the delay. South East Michigan weather is making it impossible for my to test ranges. I did however fix my saggy barrel and all it cost was 1.16$. I got a few CPVC and PVC 1/2" couplers. Stick the CPVC into the CPVC coupler. Then put the CPVC coupler into the PVC coupler, it should fit great. Then, if you have a dremel then sand out the other CPVC coupler so it can fit onto the stock barrel. The stock barrel is a tiny bit to fat to fit into it. If you don't have a dremel, like me, then have fun sanding! Took me a LONG time to sand it all out. Now to go outside and scare the crap out of my neighbors.


RANGES
[/u][/b]

I finally got outside to do the ranges. After 10 shots I got this as my average.

Flat: 101.5"
Angled (wind started to pick up): 120"

Average ranges I believe and thank God I am done with this!

Because I was going back and reading older things for fixing I noticed that you plugged the wrong holes.  Those are the ones that you shouldn't cover.  Just pointing that out.  My unplugged barrell relocated LBB gets 120-130 flat.
