I recently did Captain Slug's Big Blast mod and found out something rather interesting:

You can fit 1/2 inch copper pipe into a 1/2 Cpvc coupler, which can THEN fit into a 1/2 inch PVC coupler.
These connections are quite tight and do not need glue or tape.
This barrel turned my big blast into a welt-inducing longrange rifle.

Has anyone else tried this / what do you think?

So, I have decided to begin designing/building a homemade. Not sure when it will be complete but hopefully soon. My plan is going to be loosely based on carbon's SNAP 4, with the barrel parallel to and reversed - rather than inline - with the plunger tube.

I was going to try something I haven't seen before, and have two plunger tubes about half the length of carbon's desing. These we be joined with a pvc tee-joint before going to a single barrel.

My other idea was to have a shorter plunger tube with a greater diameter.
My reasoning is that both of these designs should be just as effective as the standard SNAP. They may be even better because the plunger(s) has to travel a shorter distance, and may deliver the air to the dart (stefan) more rapidly.

Just wondering if anyone knows of any serious issues with either these designs or if they have been done before and I missed it.

Feedback would be cool, and feel free to call me a moron if my idea sucks.

Also, thanks carbon for your sweet write-ups
