The Bravo Company Manufacturing PNT Trigger Assembly is precision machined from MIL-SPEC AISI8620 investment castings. The PNT then undergoes a 3-step heat treat and case hardening process for optimal grain structure alignment, yielding a stronger and more wear resistance product.In another 3-step process, the hammer and trigger are finished. In the first step, polishing, the sear engagement surfaces are ground, then hand polished for increased smoothness and reduction in friction up to 300% beyond MIL-SPEC.Next, an electroless nickel finish is applied for a smoother trigger pull with a crisp break. Nickel also provides a long-lasting finish that will not corrode, rust, or discolor due to oxidation.Finally, Teflon particles are embedded in the nickel, further reducing the friction of the interface and ensuring a long-life for the coating.This assembly includes BCM's impact resistant trigger and hammer pins. They are centerless
