Ok, as K9turrent described, the BBCB is a pretty good stock gun. I can vouch for it hitting 30ft flat on several occasions out of the box. Well, it's time to change that to something a little higher.
STEP 1. Remove all your screws. There are an obscene amount. No caps or anything. Here is a pic of the internals to reference:

So go ahead and rip out the plunger tube. One thing I found iteresting is the spring (which is pretty weak, I actually do have a replacement for it) is tapered at one end. One end is wider than the other. Fit a dremel drill bit into your dremel and widen the hole at the end of the plunger tube:

Don't over do this. It will ruin the seal with the shells. I also liked how all the moving parts were very well lubed. There was no need to apply lube to the plunger head. Put some etape on it, but I was out so I didn't.
Now, believe it or not, we are done with internal modifications. Close it up, and make sure it rotates well. I haven't had any skipping problems, it is like the razorbeast on crack.
Next, the shells. Well, they are buzbee shells that snap together. They have huge restrictors. When I put my hand on the end of the barrel and fire with no dart, I can feel a good burst of air hit it. With a shell in, nothing. Take that same dremel drill bit and take it to the hole in the back of each shell. Make it look something a little cleaner than this:

There is a ring on the back of the shell, get rid of all the plastic in that, and drill out the barrel post.
Now take your dremel sanding bit and sand the shit out of the inside of the shell, enough to fit some PETG in. End result should look like this:

Now take a small piece of 17/32 brass and cut it to about 1/2 inch. Glue it into the back of the PETG:

Cut the PETG down to just overlaping the end of the shell:

Hot glue it in there. Clean up any residue glue on the lip, or it won't rotate properly.
Rinse and repeat 29 more times. I only did it twice before doing the write up. I did one without the brass too, accuracy went up.
You are done now.
Now the part you have all been waiting for: Ranges.
I don't have a good length halway in my house, nor an open area to test it in. My longest hallway is 35ft long, and the darts hit the end of it with a bit of drop and a good smack. Im going to guess 50-55ft. The spring can definitely be replaced, and the plunger seal isn't the best either. The faux barrel also kills range a bit.
Expect another episode of the BBCB in a few days.

Nice first mod for a new gun. I think there will be a whole sleu (sp?) of mods that will make this gun a serious primary. Nice work! Any ideas to make this gun fire stefans?

The shell mod removes the post, so it does fire stefans. The ranges posted are tested with 1.5 inch 3/0 fishing weight stefans.

Nice WU (new aberration for Write-up)
I might buy this blaster after all.

[k9turrent]

awww you bastard, I wanted to post the first mod. good job

[Draconis]

Looking forward to something awesome from this blaster, so keep working on it! Good start to it, but I want more range!

Im sure the range will go up once I add the new spring (It was a replacmemt for my sawtooth, which also has a tiny plunger tube) cut off the front of the gun where the faux barrel is, and work on the shells a little more.
I think this thing could break 70ft with enough mods.

[deadshooter711]

I must have this gun. The ROF and belt capacity is the one thing that amazes me. Good job on the Modifications.

Where did you get it?

Is this a newly released gun? because I have never seen one before. I wonder if you could mod it to fire vulcan chains? This gun could have some potential.

Why? This shoots 30, the vulcan shoots 25. And, this gun is only $20. For $40 you could easily get 2 guns and a 60 dart belt. It would be a lot cheaper just to get this gun and keep it with it's original chain.


Yes, it is a newly released gun.

yeah, but the thing is, you can buy 25 round vulcan chains that come with 25 darts for I think $8? So, you could invest in alot of chains and basicly have a limitless amount of rounds to fire off.

But, as stated, the links in the chain are the same size as other buzzbee shells, so I doubt there is actually a way to make it fire vulcan chains.

However, this gun looks to have GREAT potential. I'm thinking you could probably get the gun to shoot up to 60 with stefans with the right modifications. There is also tons of empty space, particularly in the stock. SO it might be possible to intigrate a 2k or other pump gun into the shell. ALSO...if you saw off the front handle that you use to cock the gun, you could super glue on a nitefinder, and then you could have 3 guns in one. One rapid fire gun for short range. One at2k (or other pump gun) for long range, and then a sidearm to use while reloading. It might just be one of the most useful guns.

I'm definately buying one of these when I get the chance!

If you saw the front handle off, how are you going to cock it then? Maybe a better integration could be a maverick, that way you can move the cocker back and forthe, and cock the mav without having to move your hand, which would make it easier then putting on a nitefinder. But other than that, that's a pretty good idea.

[mystefansdontflystraight]

No, front handle is staying in place. I may integrate a 2k, but this think is really pissing me off, I have tried 4 replacement springs, and they are stronger than the stock, but somehow DECREASE range. Makes no sense.
Ill update this with part 2 hopefully this week.

[Draconis]

What does the plunger head look like? Perhaps it's a matter of the seal degrading slightly as it get's used more.

There is a possiblity it is the seal, but not where you are talking about. Try adding another O-Ring, or maybe even a little E-Tape under the O-ring, and you should get some better ranges with a new spring.

[Shrub]

Well once you get the seal, spring,fuax barrel fixed you should get a really good weapon. Nice mod hope to see more like this.
