Ok after much thought an consideration i have "scraped" The tripple s

i now plan to make a new gun with stats guessed at the following:

- 16mm barrel(rifled 16mm soon to come)

- Slimmer design than the triple s.

- researched 2 piece piston ( the main part i am focusing on ). soon to come it is an o-ringed aluminum peice.

-18mm port.

- 30mm chamber: 2:1 barrel ratio with 16mm barrel.

- better ergonomics.


ill get some plans up on here soon i hope.

edit: scratch that i might enter it

peace all

Wait... did you actually throw it out? If so, why?

Anyways, good luck with this build. It would be a good idea to have a chamber:barrel ratio of 2:1 for all the barrels, rather than just one.

What do you mean by two part piston? Are you talking about one with an internal check valve? Are you talking about one that involves half of the piston as a piston stop, and the other half as the actual moving piston (like the Supah Valve)?

I've got photoshop but I used the gimp because I've used it for so long I know what all the controls do and I can't be bothered learning all the bits of another graphics program.

The photo itself wasn't edited though, just a border and some text effects.
