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.

Safe diving,
