Amazing work, earlier this year I drew plans to make something like this, but the feeding system was not as reliable. Also instead of firing one dart at a time I pleaded to have a 3 in feeding ramp to use streamlines or 2 Steffens at a time to have a " shotgun" effect, but all in all this awesome.

This design could easily be adapted to use shells to shoot 3-darts at a time.

Because I truly have nothing better to do over the summer, I decided to create a 3d model of a version of this, specifically made to drop in to a revshot with little modification. At least, one of my revshot designs. It comes with internal aluminum priming bars that connect directly to the plunger tube and a kind of ugly fore grip. Pretty rough right now for the internals, but is mostly complete. i just have to complete the dart loading ramp components and make it look sexy.



It won't really be bronze tinted and photographed in space, but it made most of the components relatively visible. You can't appreciate a 3d model in a picture.

That looks amazing! I'm looking forward to seeing the final product.

Thanks for all the kudos!

This is truly incredible. There have been multiple people over the years that have tried to replicate this, and I think every one failed except for one guy that got lucky. so props to you for making something assumed impossible by many.

I really want to believe that the range is 80-90 ft PTG, however:
1. Although ingenious, the sealing mech does not look like it seals perfectly/near perfectly
2. You have 3" draw with a 3/4" plunger tube. Blasters like the snap use 1 1/4" PT's with more draw and get just slightly higher ranges

Regardless of range you just created a completely new breech setup that (judging by your video) works consistently, so well done. I'm sure once other people try making their own variations and polish and enhance this design, I'm sure the range issues will be solved and be brought up to standard homemade range.

So yeah, well done on inventing a new breech setup, creating something most viewed as unachievable, and making it work consistently. I'll have to try making this one day as it looks super fun to use.

1. Bolt seal at the front end with the coupler is excellent. The seal at the rear is also fairly good.
2. 3" plunger draw and 1 1/4" plunger tube diameter is enough to achieve such ranges.

This is really cool! It's good to see something out of the mold. I think it's really cool the way that you designed this with a real weapon in mind. Kind of like BoltSniper did on his homemades.

I'm curious about the ability of this design to be reproduced. Do you think that people other than you can build one, or is it one those homemades like the FAR, which is basically impossible to build? Also, how strong and reliable is the feeding mechanism?

If I get the tools, I'll work on something that can be more easily replicated. All the parts can be made with polycarbonate, so I'll make some templates for the build in the future. The only unusual part is the loading mechanism, so this should much easier to construct than the FAR. All the other components are pretty standard with SNAPs and other homemades.

Nope I clearly get how it works as I stated but I wanted a video as well.

I'll try and get a video for it soon.

I can't believe you actually got a tube magazine to work. There was a thread by Shadow, and it lasted for two years, just barely touching on successful prototypes. And you managed to do it with just pvc and paint sticks.

Now, how many darts does the magazine hold? What flaws can you currently find in the design and construction of the blaster? How reliable is the tube magazine?

As Azrael said above, it holds five 1.5" long darts. The tube magazine is reliable as long as the darts are the same length and there are no more than five darts in the tube. The construction is solid, but new designs need to be made so that the blaster can be easily replicated.

Wow, like many of the others have said, this is an amazing design that is not too hard to replicate at all. I definitely hope to try and make on of these in the future. Also, judging that most of the blaster are PVC and wood, would this be a fairly inexpensive build? Again, great work on the loading mechanism.

This would probably cost $30-40 to make. It was a lot less for me since I had all the leftover parts from my SNAPs.

06 - Catch System

The catch is basically the one from my RAINSnap writeup.

Disassembled.



The stock is made from a 3/4" PVC tee, electrical tape, and 3/4" CPVC.



The catch is 3/4" CPVC and a 3/4" coupler.



Front of spring rest. The ridge in the 3/4" CPVC coupler is where the spring rests.



The rear of the spring rest consists of 3/4" CPVC inside the coupler nested in a 3/4" PVC coupler.



07 - Plunger

The plunger head is based off of Rork's Superlative Snap Plunger Head. I don't have exact measurements for this old spring, but I do believe the wire diameter is around 0.07" and it's from Century Springs.



There is a 1/2" nylon rod connected with nails with the ends dremeled and filed smooth.



08 - Handle and Trigger

Full view. Two wood screws hold the handle halves together.



Top view. Four wood screws attach the section of 1 1/4" PVC Coupler to the wood. 4 sheet metal screws attach the handle to main body. The plastic bit at the end of the 1/8" steel rod is made from a 1 1/4" PVC coupler.



Internals. The trigger is made from the stirring sticks. There is a thin sheet of plastic supporting the small spring.



09 - Pump Handle

Front view.



Rear view.



Disassembled.



1 1/4" PVC.



3/4" CPVC and 3/4" CPVC tee.



3/4" PVC coupler.



10 - Firing Video



I would estimate ranges of 80 to 90 feet. I'm still experimenting with the ideal barrel length.

Thanks for reading!
