The Bravo Company BCMGUNFIGHTER PNT Trigger and PNT Hammer are a precision machined Mil-Spec AISI8620 investment casting per the USGI TDP (Mil-Spec) for M16/M4 family of weapons. (not to be confused with MIM parts that are very common in the commercial market). 156/157 holes are honed to assist in perfect alignment and a smooth trigger pull. After that, the BCM PNT Trigger and PNT Hammer then goes through a 3 step heat treat and case hardening process for optimal grain structure alignment, yielding a stronger and more wear resistance product. PolishedThe sear engagement surfaces are ground, but then hand polished for an increased smoothness and reduction in friction up to 300% beyond the Mil-Spec. NickelAn electroless nickel finish is applied for a smoother trigger pull with less "grit" and reduced felt "creep". Nickel also provides a long lasting finish that will not corrode, rust, or discolor due to oxidation. TeflonTeflon particles are embedded in the nickel, ...
