Well I have sent a beartooth magnum back to them twice to have the the action release lever replaced. The second time I just sent the receiver with the parts still on my reassembly pins. They did send me my assembly pins back also, as requested. They fixed it free both times. I called them to have them send me the lever so I could fix it myself, but they wont sell just parts. Your Optima or Optmia as you spell it has the same parts I believe.

IMHO, this action is a poor copy of the H&R design. The lever that open the action has broke twice for me.
