aluminum tubing w/rail?

[apnea_beast]

does anyone know of a source for some aluminum tubing with the built in rail such as that used in rob allen/rabitech guns?

i'm also looking for thicker(32mm OD) railed tubing that is used on the picasso century pacific and the edge/superfrog guns.

any info would be a big help.

i'm in the U.S., so domestic sources would be better

thanks

Home of HammerHead Spearguns. Don't know though if they have 32 mm OD tubing. Hope this helps.
