The processes and tolerances are matched in the BCM PNT Trigger Assembly to create a system better than the sum of its parts. All hammer engagement surfaces are also ground for a super clean reset. The BCM Disconnector is stamped from a 1070 material and fine blanked for cleaner edges, double disc ground to precise size. They are centerless ground to a fine finish and superior tolerances to ensure compatibility with all MIL SPEC lower receivers built per the USGI TDP. This assembly includes our impact resistant trigger and hammer pins. This is done on both the BCM PNT Trigger and Hammer in order to provide the maximum benefit allowed by the nickel coating, by augmenting the low friction and corrosion resistance. Teflon particles are embedded in the nickel, further reducing the friction of the interface and ensuring a long lasting coating. Nickel also provides a long lasting finish that will not corrode, rust, or discolor due to oxidation. The sear engagement surfaces are ground, but then hand polished for an increased smoothness up to 300% beyond the Mil-Spec.Īn electroless nickel finish is applied for a smoother trigger pull with less grit and reduced felt creep. 156/157 holes are honed to assist in perfect alignment and a smooth trigger pull.Īfter 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. (not to be confused with MIM parts that are very common in the commercial market). The BCM 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.
Please look at the information below.īCM PNT Trigger Assembly (Polished Nickel Teflon)īCM quality, modern manufacturing processes, and aerospace coatings are combined to ensure parts last a lifetime while performing far beyond requirements established nearly six decades ago. In a commercial market flooded with imported and low quality Mil-Spec imitations, you can trust that BCM parts are made in the USA and to the highest standards. This kit includes all the Mil-Spec quality components you have come to expect from BCM, along with some fantastic upgrades to include
