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.

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.

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?

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.

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.
