Hey all. So I'm new to modding and homemades but I'm super excited I found out about it. I have been searching around quite a bit and have not been able to find an answer to my questions. Basically I'm also very much into the aesthetics of modding too and have been wondering if anyone has ever tried to put their homemade blaster into a nerf shell?

From what I can tell the Bullpup design looks like it would fit the best. I was thinking either an Alpha Trooper or Deploy shell. Maybe a Recon? My other thing was that I'd rather not have a hopper sticking out so I was wondering about the compatibility of the RSCB clip with the Bullpup design?

On a side note, is a bolt slide like the Snap Clip Carbine compatible with the Bullpup? Are there other designs out there that might work better? Thank you for any info or pointers you can give me.

Unless you can make some new revolutionary design changes an RSCB won't work in a bull pup configuration. The RSCB feed tube has to sit behind the back of the barrel. You tip the blaster downward between shots and the next dart in the feed tube slides forward into the back of the barrel to be fired. To work as an RSCB you would have to have a drop down slot and hope the dart falls from the feed tube to the barrel back. You'd also be tipping the blaster up to send a dart to the back and then down to seat the dart forward into the barrel. (A minor procedural change). That drop down slot would also introduce a bit of dead space. 

 

Homemades are huge. They're designed with a massive plunger tube and amount of travel. You'd need a very spacious shell to get one to fit. A deploy might work - but you would have to shorten the plunger tube considerably. You might have more success with a long shot shell. It would still be tight diameter wise but at least you could have a near full length plunger. A centurion might also be a good sacrificial candidate.

I know I've seen this done somewhere before, but I'm not sure to what extent. That pic is of a homemade PT in a blaster that is, essentially, a PT with a trigger. I thought someone had put a SNAP/rainbow into a L-shot for sure, but I can't find pics of that.

I think you're confused by what the term "Bullpup" is referring to, none of the blasters you mentioned are bullpups. This is a bullpup configuration blaster. Bullpup means that the ammunition comes from behind the handle. In real-steel, this can make for a shorter weapon. In NERF, it means a blaster that has a basically built-in stock, since you can't shorten the thing much past the length of the clip + flywheels.
 

My other thing was that I'd rather not have a hopper sticking out so I was wondering about the compatibility of the RSCB clip with the Bullpup design?

As shmmee pointed out, it's not. I know I've seen people put RSCB's/Hoppers on longshots though, so that's definitely possible, just not as a bullpup.

Not technically true. If you took an ESLT, for example, and replaced the CPVC 90-degree bend with a tee and used that as the upper half of an RSCB, it would work.

There have been lots of homemades in blaster shells (e.g. tons of Crossbows, tons of Nite Finders, Tornadobows, Zorn's FAL in the Super Soaker Tornado Blast), but Shmmee is largely right, especially if you're going with a tubes-in-tubes design (maybe excluding Zorn's Fallopian blasters). I agree that a Deploy would probably be a good choice if you wanted to maintain pump-action or a bullpup configuration, but for the most part the easiest thing to do is to put a +bow-style core into a Nerf shell, since those fit into more tubes.

I have done exactly this with my RainbowPup, and it works very well.

You wouldn't happen to have pictures and maybe some build details of your Rainbowpup?

By the way thank you all so much for the info. So I'm gathering that a bullpump won't work for my project but an ESLT and Rainbowpup will. What are your thoughts on a Snap Clip Carbine? I'd prefer to use the Alpha Trooper shell but the Deploy works too.

If I were to use say the Snap Clip Carbine, what am I looking at power improvement wise over just modding the Alpha Trooper or Deploy? I'm pretty sure the ESLT and Rainbowpup are huge improvements.

Also is it really that bad of an idea to use a [k26] spring in a Snap Clip Carbine? Is there a noticible power difference with a k18 in the same blaster? Thanks again.

Sorry, I didn't build the blaster, I bought it from Cheerios.  Typical homemades will have five to ten times the plunger volume of the AT/Deploy/Recon plunger.  There is no contest.  Most people are happy with the ranges and effort associated with [k26] springs.  Personally, I prefer the [k25], which is a bit lighter.  But that's just me.

Do you have a picture of it? I'd like to see the RSCB setup. Does Cheerios still sell blasters?

I just had read that people were having a hard time with the [k26] in the Snap Carbine. I wasn't sure what the difference in spring and plunger power was with the k18 Snap Carbine over a modded AT. Say if the Snap Carbine is the only one to fit in the AT shell and it can only use a k18, I was wondering if I would just be better modding the AT.

So I found this video with a blaster by somebody named Modman. The blaster is called a Rain Pup. It looks perfect for putting on a RSCB and fitting it in the Alpha Trooper. I can't seem to figure out how the seal, at the part where the hopper conects, works. As far as I understand the rod travels into the plunger tube. Is it just the it's easier for air to leave the barrel rather than the seal?

Is Modman still on here?

I think at first, you should just build a snap carbine. They're cool, and you can probably make it a bulpup by putting a trigger up further and a rod pushing the snap trigger, but do you really want to have the rod accelerating so close to your face?

I think DIY blasters are fine out of shell, but if you find a blaster that houses 1-1/4 PVC plunger tubes, than it's fine.

I wouldn't even do that. Do a pump snap or pump bow; those carbines seem like more work for no added benefit. Then drop it in a shell or not.

I think you might be underestimating how big these blasters are.  There's no room in an alphatrooper shell for a homemade like that.  To my knowledge, no one has put a homemade inside of a nerf shell that is pump action or hopperable.  This longstrike is the closest thing I could find..  If you're determined to put something in a nerf shell, you'd have much better luck using an airgun.  The winner of the mod contest is a great example of this, it's a blastzooka inside of a crossfire shell. 

 

The blaster in that video based off the RainbowPup, which evolved into the ESLT. The third link below is a writeup for how to build your own ESLT, and the second post in that thread describes how to do it without a 3d printer.

http://nerfhaven.com...tubing-blaster/
http://nerfhaven.com...er-build-guide/
 
My advice would be to start with something simple, like building one of the homemade designs from the contest we held or maybe trying to build the ESLT design above as-is.  Which design is best for you will depend on what materials and tools you have available.   Once you've gotten some experience building a homemade design and getting it working, you can explore different options for making it look the way you want it.

Anything snap is easier in my experience, I just really like the carbine because no need for plunger rod Meaker.

I also would like to add, I agree with Langley that you should work on a beginners homemade. Those are just easier in my experience, and shouldn't be too hard. If you're really insistent in trying to put a homemade in a nerf shell, see if you can fit 1-1/4 in PVC in it. You'd probably have to cut out a lot of supports too. The only thing besides putting it in an LSK is a nitefinder rifle, and I don't remember if those hop.

I'll probly end up doing the carbine. While I do have access to a 3d printer the Rainbowpup and ESLT need it more than I'd like to get into for this project. The main reason for wanting the bullpup design was so I didn't have loads of extra barrel out the front but I think I can work around that. Could also do the pump snap but not sure if I wanna try and get the Alpha Trooper's pump working with that.

I'm pretty sure 1-1/4 tube will fit in the Alpha Trooper. I was already planning on gutting the inside. I like doing things the hard way.

The first pick is what I'm going for the second is the internals, the lower one being the AT. I also have a deploy to work with too. I have a longshot, would way rather a longstrike though.

please please please please PLEASE don't do anything flat noob black.
Tactical stuff is very borderline, and not good. Today in Austrailia MakeTestBattle just got their swat on them, and tactical stuff isn't looked on too great in the hobby for that reason. 

That being said, if you have a 3D printer you can 3D print a rainbow mech, (literally you can print most of it, I saw it last week at NENO 15) The carbine or any other snap variant is great if you're gonna do full homemade from DIY sort of materials. 
To add onto the 1-1/4 in part, that can house inside an Alpha trooper with enough gutting, but you also need to factor in if you're making it pump action and how would you connect that. In the 1st pic, I think that's 1-1/4 in as a barrel extension so you know. Just work on building a homemade first, and make it work without fitting because there's more places to go wrong or mess up putting them into a shell.

SNAP is way easier, but then anything Carbine is hard again (more machining). Start with a pullback/pump SNAP, then do a carbine.*

Agreed. Don't do that. It's really for your safety more than anything: bright colors help tell everyone around you THIS IS A TOY and prevent the cops getting called.

...While I do have access to a 3d printer...


Shoot son, if you've got access to a 3d printer do a PSCR. There are like 5 cuts you need to make to the PVC, then the rest is just putting parts together and screwing them in place. No MCM order except for the spring and 1/2" rod (and skirt seal, but I'm going to try using my oring plunger head instead of the skirt seal plunger head), which you'd probably be able to get elsewhere (ACE or HD spring, 1/2" dowel maybe?). And the blaster looks pretty good on its own. I've now printed all the parts except the front grip, and so far it's been something like 200-500 grams of material, depending on your settings. You could cut that pretty significantly by building a handle or using your deploy handle and just drilling it out for the trigger mech.

So I may catch a lot of flack for this but... Anyway the reason I'm going for a realistic looking mod is that it's for a LARP. So going for high immersion. Otherwise I wouldn't never think about it for a regular battl.

Well you're holding it in your hands aren't you? Pretty real to me. Yes I know you're attempting to model it after something. I highly would advise against that, any trouble you get with that puts a bad spotlight on the rest of us. Please, always try and have it as toy and non suspicous as possible.
You not feeling as cool that whatever blaster it is, isn't very tactical is better than potentially ruining the hobby. TBH, the pipe aesthetic also kinda grows on you. Building it makes you appreicate it more, and if you really wanna feel larpy, pretend it's some sten gun variation.

I've been seeing a lot of this kind of thing on Reddit lately. I hope that the rules governing your LARP are set up to avoid conflict with authorities and/or you have a location you can play without trouble. If you're doing blasters for the kind of play we're used to here, black is a problem, but from what I've been reading, there must be some kind of group that sets this stuff up carefully to avoid problems.
