The bigger one weighs about 14-15 pounds and the smaller one weighs about 9-10 pounds. I just plopped them on the bathroom scales so I could be off as much as a pound I guess. They're black painted steel I had made for my old starfinder which I sold awhile back. They have a 1 inch bore and knobs so you don't need to use an allen wrench to loosen and tighten. They have some chips in the paint.
Asking $40.00 + $10.00 shipping for the big one and $30.00 + $10.00 shipping for the smaller one, or $60.00 + $15.00 shipping for both OBO.
