Hey Jordan. Welcome to the fold.
This website has some info on rabitechs and Florida Freedivers sells them, but only w/ carbon barrels. Email
Cherryl at Florida Freedivers and she'll send you a price list. Please tell her I sent you.

P.S. I have the aluminum 130cm Rabitech and think it's great. Much quieter than the RA and I like the handle trigger mech better too.
