I have a mid 90's Jewell Trigger installed in my AR match rifle. The right pin retention spring broke at some point and no longer functions. I know about various anti walk pin sets but I'd like to keep the original trigger pins. Does anyone have a set of instructions or an extra spring? I did contact Jewell and they do not have parts for that trigger mechanism any longer. They only mfr and support a trigger aasy for the Rem 700. Thanks
