Now that I have your attention, I'd like to show you a Berserker with the air tank hooked up to the turret - the two blasters 'fused' together. 20 shots, 4B ranges, and all that good stuff. I also replaced that gawd-awful handle with one from the Longshot Front Gun and installed a little somethin-somethin in the middle of the turret. I dub this thing... DAIKAIJU! Means 'giant monster' in Japanese.

This mod is dedicated to Muttonchops, who mentioned the original idea at Apoc 09. Soon afterwards, he took a 3B barrel to the face, meaning that someone up there did not want this blaster to be made.

It's a little tough to pull apart and reassemble, so this isn't a true write-up. I'll touch on the interesting bits, which will hopefully be enough to make your own.

Posted Image
Here's a pic of the internals. The air goes out of the top of the tee, through an elbow, and into the top barrel. A cut-down neoprene washer helps prevent some air loss. I tore out the now-obsolete springer components.

Posted Image
This is the bread and butter of this mod. In a stock Berserker, the missile-launching post is attached directly to the air tank, and serves as the spindle for the turret. I sawed off the entire barrel, down to the blast chamber itself, and replaced it with a CPVC tee. Note how the tee is cut down to lie flat on the blast chamber - this ensures that the turret actuator can move correctly.

I plugged up the end of a piece of CPVC and inserted it into the tee to serve as a new spindle. To get the actuator to fit, I enlarged the hole to fit over the tee. A few wraps of electrical tape eliminated the wiggle room. I added an extra spring to the ratchety thingy so the pump could apply more force to turn the turret.

Posted Image
To kill the air restrictors, I used a 1/2" spade bit to annihilate the entire contents of each barrel. To fill the dead space and create a better seal, I hot-glued a segment of stock dart into each barrel and melted off the excess with a high-speed Dremel. Not the best solution, but it worked.
I replaced this with a new turret for rearloading action!

Posted Image
To get the air pipe to fit, I had to cut a slot in the shell and clean out some of the plastic. It's pretty straightforward - just grind away till it fits.

Posted Image
I hacked off the Oompa-Loompa-scale handle, ground the tabs off a Longshot Front Gun handle, cut a slot in the shell, and Fly Tier's Glued the handle in. Fits like a glove. The topmost screw on the new handle will be covered by the Berserker shell, so remove it first.

Posted Image
I drilled a hole in the LSFG handle's trigger tab, bent the longer firing pin to fit, and installed it all. The trigger pull is just enough to set off the blast chamber, and the internal extension spring makes the trigger spring unnecessary.

Posted Image
The finishing touches - A King Ghidora 'hood ornament' and ten feet of PETG. Why PETG? It's nice and light. Why not 20 feet? Because 10 feet is all I had!

Here's some gun porn for ya:

Check out Version 1.1, with rearloading and a basketball pump!

This mod took around six hours over two days and cost about $35, including the Berserker.

Doing this as I speak. I have no idea when I got it...my DAD got it some 15 years ago, but that doesn't matter. Anyways, it keeps jerking around all over the place. I try to hold it with a rag...It doesn't look like...much.

Do a pump replacement, finish off the barrels and we got some competition for the Doomsayer. By the way, nice garage!

Looks really sweet. 20 shots with a BBBB without reloading? Sweet. Plus my main comment on this gun is it looks extremly clean. Very well done.

Very nice! Im assuming the loss in range is due to the dead space. I wish my berserker had come with a bbbb tank. The other tank shape/size doesn't seem to be as good, then again with 20 shots who needs the range?

I have to say....this is very cool. Major props to you for seeing the best in each part of this blaster, and then having the ability to merge the two successfully. Like others said, do a nice pump replacement--and you have a real beast on your hands. Again, Great work!

Thumbs up, man, that's just great! It fires out of the top now, too! I love it when people slap animal/monster heads or skulls on their blasters. You should paint the rest of it with 50's Japanese monster movies art. A video would be good... Again, fantastic work, very clean too!

Couldn't you just take a heat gun to some CPVC and bend it so it fits in the shell? This would remove the need of an elbow and cut down on the dead space.

The yellow balls are also slightly smaller in diameter than the green ones.

It's going to get a hammered-gold paint job, and the side sticker will be replaced with a piece of a Godzilla movie poster. It needs to wait, since spraypaint doesn't come out well in cold weather. It will eventually get a video, though.

Couldn't you just take a heat gun to some CPVC and bend it so it fits in the shell? This would remove the need of an elbow and cut down on the dead space.

I suppose I could. That will eliminate the elbow, but how would that save dead space? Also, getting the length of the CPVC segments is pretty tricky.

in theory, this could work, especially since the cpvc wouldn't be operating in a pressurised capacity (ie as a tank), so you wouldn't need to worry about compromising it's integrity. However, bending pipes with heat guns is iffy at best, and bending them to the tolerances needed to both fit the shell and achieve a tight seal to the turret... well, I wouldn't try it, but you're welcome to!

EDIT: ugh, ninja'd

It wouldn't be worth it for deadspace reasons because the rotation mech is preventing it from traveling along the hypotenuse. All you'd be saving is maybe a 1/4 or 1/2 inch on height. If somebody in the future wanted to try and keep everything in the shell, it would make much more sense to just use some type of tubing that is already flexible.

But enough conjecture, this blaster is pretty sweet as it stands. You should try to give it wings and a couple more King Ghidorah heads.

↓ Awesome! Like Monster Zero, this blaster is gonna be a total badass! Also, I didn't realize that the cpvc was bracing the turret, that's actually a good thing since it probably helps a lot with the seal.

I don't think that would work - the rotation mech is actually braced against the upward air pipe. Normally, it's held in place by a green bushing on the missile tube, but once this mod is performed, the air pipe serves this purpose. I feel like a flexible tube would jam the rotation mech and eventually get sliced through, but definitely give it a try!

You should try to give it wings

Rearloading and a pump replacement do seem to be pretty popular requests. Because of the sloppy way I closed up the turret, rearloading is impossible, but I could add it if someone would give me a replacement turret (wink wink).

I'm still trying to find a good place to drop a new pump. Any ideas?

I would maybe use the bend in one of those straws with the bendy top ends to "straw mod" the elbow and cut down on deadspace.

Also a pump replacement doesn't really have to go anywhere, just stick it in the spot the current pump is. As for rearloading, I don't know how fucked the back of the turret is. Pics would be nice.

Hope this helps you out man.

The problem with flexible connections on the outlet of any firing port is that they're ... flexible. When the blaster fires, it will absorb part of the energy.


I think he is reffering to the straw mod on the mav: Putting it inside the plunger tube, in this case the CPVC. Wrapping it in tape a bunch of times and gooping it into the cpvc connections might improve ranges.
I really like this, I hope beserkers come to Canada soon.

As for the pump, just do like Rork does with his decrapified MMs. The pump can be in the same place.

Just for clarification, you pump the gun, cycle the shotgun style grip at the front, and then fire?

Maybe I missed something...but you removed the spring plunger system? I don't see why you would do that. The best feature of the blaster is that you have long range and high ROF. You still have long range and decent ROF, but not high ROF. Was it a space issue or just an issue with the handle or is it there and I'm just mildly retarded?

It is a brilliant idea and I like it, but I think it could be better. My (unfinished) version leaves it in the center but adds a Marvelous Salvo to the turret for a Seoul Style Smackdown (wow, I feel stupider for having actually typed that...it stays).

Why didn't you leave in the spring system, but just direct the BBBB part to the top of the turrect as you did? it would allow for both, since one fires from the top, and the other the bottom. The only problem is barrel length.

I thought about that, but decreasing the inner diameter would also restrict the airflow. While the elbow puts in a lot of dead space, the 4B tank also moves air very quickly. I'm not sure on this - does the restricted airflow outweigh the dead space?

Just for clarification, you pump the gun, cycle the shotgun style grip at the front, and then fire?

Exactly! The pump action is still fully functioning.

I took out the springer for a few reasons. First, there's no way that pissant little plunger tube would manage to get a dart down a foot of PETG. Second, it would make the blaster harder to pump. Third, it increases the number of breakable moving parts. Finally, the LSFG handle doesn't have two triggers.

And of course you'd add a Marvelous Salvo to it, Seoul. You put Salvos on fucking everything. That's a really good idea, but 20 isn't a multiple of 3! That kind of thing bugs the crap out of me.
