I have 2 Nitrided 9310 Bolts that I pulled from new Toolcraft Nitrided BCGs that I got in today and do not need. The bolts were advertised as "9310 MPI bolts" (but the bolts are unmarked) and the bolts come complete with the extractor (o-ring installed), ejector, gas rings and I will include the firing pin that came with it as well. Will sell each complete bolt/firing pin for $30 shipped or both complete bolts/firing pins for $55 shipped (USPS MO or discrete paypal gift). Email for pics. First post "I'll take it" with a followup email gets it. Thanks for looking.
