Ok so this is my first write-up and my first breech so just bear with me. I am doing the best I can.

So I found the Buzz Bee hunter at my local Gordman's and decided to buy it. Stock the ranges aren't that great. I tried a simple cpvc barrel replacement and that made them decent but it was very hard to load. So I decided to man up and do a breech.
First off you will need:
-Buzz bee hunter
-1/2" cpvc
-Dremel
-Drill
-hot glue
-plumbers goop (or another glue of your choice)
-Philips head screwdriver
-e-tape
-silicon spray (or other plastic safe lube)
-cpvc fitting* (see picture below)

Not sure what it is called but it can be found at Lowe's/Home Depot/ACE. When you unscrew those caps there is a rubber fitting underneath.

Here is the Hunter next to a nf for size comparison.

Ok start by opening her up and throw away the fake barrel piece in the front and the piece at the front of the dart barrel that folds down to let the gun fire (sorry I don't have a picture of this). This step is fairly simple.
Next do a seal improvement and a spring replacement if you wish (I only improved the seal.)
Next you will need to drill out the barrel to the very back. Make sure you drill past the air restrictors. You will also need to widen it enough to fit the cpvc in it. You will also want the cpvc to be able to go to the very back.

(Note this picture is only to show the cpvc inside the barrel, DO NOT glue a segment of cpvc this size into the barrel)
Next you will need a long piece of cpvc to use as the barrel. Fit the pvc into the old barrel and glue it in place with plumbers goop.
Here is where it gets tricky. You need to measure the cpvc and cut out a section for the breech where the front of the opening in the body is. If done right it should look like this when it is put back in the shell and the bolt is pulled back.
Posted Image
Next you will need to spray your barrel and the inside of the fitting off with some silicon spray.
The fitting gets tighter as you screw the caps on further. you will want to adjust them so that the fitting can slide over the barrel easily but still be reasonably tight over the barrel. This is important because if it is too loose it will not seal, but if it is too tight, you won't be able to cock the gun.
Now you will want to place the fitting in the shell right about here.
Posted Image
and dremel out the shell in order to get the fitting to fit in. You may also need to cut out part of the shell.
Once you get it to fit you should re-assemble the inside of the gun. With the barrel already inside of the fitting. Then use hot glue to secure the fitting to the shell.
Posted Image
(Note that tube piece is supposed to be a little crooked.)
Now you should put it all back together. (Make sure you don't pinch the air tube)
Posted Image
And lastly cut down the barrel to an appropriate length. I cut mine down so that when the gun is cocked it is even with the fitting.
Posted Image

This works best with 1.5" stephans that fit fairly loosly in the barrel. You may need to drill out the cpvc first if you have tight fitting darts. This does not work with streamlines or other tight fitting or longer darts.

Ranges: ranges were between 60' and 70'. Probably could be better but my darts really suck.

I'm sure this could be done better with something like brass/ done another way to get much less dead space, but I do not have brass and could not think of a better way of doing it with my available materials. This gun works great for indoors and is very fun to use. It is also quite easy to reload. If you have any ideas of making this better feel free to post here or shoot me a pm (but please don't hijack my thread).

Nice, I have not see this mod before. In fact I have never even seen this blaster before. Does the bolt action both chamber the round and prime the plunger rod?

You pull the bolt action back to prime it. Then load it while it is back. Then push the bolt back forward. When this mod is done the breech is exposed when the bolt is pulled back.

I've never seen this before either and I like it more than the RFR. If it takes no shells it might just be my favorite buzzbee gun! Good mod too, and seeing this I want one too.

For those who say nerf is for kids, just take a look at this.

Good job! I have one too that I got at Big Lots and they are very fun. Good use of the fitting though, I would have never though of that.

So you got 60-70 feet with no spring replacement and all that tubing as dead space? F, that must be one HELL of a plunger tube and stock spring, I would not be too ashamed of my darts if you are getting that distance.

Now I reeeealy wants one :D

Nice write-up man, that's a clever breech set up. How much was the gun? $10, $15?
Those ranges make me go ":D". Are those angled...?

That cpvc fitting is really neat, I've never seen one before but I definitely want to use it on some of my other blasters. I just got a Hunter this afternoon, and the handle is even worse then I expected. Do you have any plans to swap it out?

So you got 60-70 feet with no spring replacement and all that tubing as dead space? F, that must be one HELL of a plunger tube and stock spring, I would not be too ashamed of my darts if you are getting that distance.

The pull is definitely heftier then any stock N-Strike blaster (well, maybe not a longshot, it's been a while since I've played with one of those). I'll be trying to keep the breech in the same place on mine, but I'm guessing a popular mod in the future will be to chop the tubing off and just have the barrel come out the bottom. Or even use the original barrel space for an rscb type setup, using the original breech to seal the clip. I might have to pick up a second one for more experimenting next week. At just 8 bucks this is a pretty good deal.

Not really. I don't have much of a problem with it. I have just kind of found a way to hold it where it doesn't bother me much.

So you got 60-70 feet with no spring replacement and all that tubing as dead space? F, that must be one HELL of a plunger tube and stock spring, I would not be too ashamed of my darts if you are getting that distance.

I have never done a write-up before so I have never tested ranges before but I did the best I could. I tried the best I could to not angle them. And when I tested my modded nf (the one in the picture) it was getting 50-60 feet.

How much was the gun? $10, $15?

Actually it was $8

The pull is definitely heftier then any stock N-Strike blaster

Yes, I wanted to do a spring replacement but it looked like it would be more work than it would be worth. Also I'm not sure how well it would hold up.
Also it should be noted that it becomes harder to pull back after the breech is added.

I would not be too ashamed of my darts if you are getting that distance.

The main reason I said my darts suck is because the darts were fishtailing a good amount when I took ranges and also because my Berserker was getting like 70-80 feet with the darts fishtailing like crazy and when I used one of my better darts it got probably around 120 (didn't have it measured that far)

Now that is a badass gun. You should try taking a clipstrike clip and attaching it to the breach.

Very cool use of an obscure peice of technology. This would have been the first time I've seen this gun, except I saw SGNerf's video on it. Makes me want to go out and buy one.

That is one badass gun you got there. If I ever buy a Hunter I might just have to try that.
