I have a Golem Gear Armadillo Tech/ Sidemount butt plate for sale. It was used for sidemounting rebreather bailout bottles & has about 30 dives on it. Absolutely nothing long with it,... It just did not work out well for me. I have found another method that works better for me. Comes with the soft butt plate, rails & mounting screws. Asking $50+ S & H.
