Hardening process yields an optimal grain structure alignment for strength and wear resistance. Sear engagement surfaces are ground and hand polished for increased smoothness. Electroless nickel finish with Teflon results in a smoother trigger pull with less grit and reduced felt creep. Will not corrode, rust, or discolor due to oxidation. Impact-resistant trigger and hammer pins utilize superior tolerances. Disconnector is made from 1070 high-carbon steel and is double-disc ground to precise size. All hammer engagement surfaces are also ground for a super clean reset. Takedown detents include a cadmium chromate coating to resist corrosion and prevent seizing in the small holes of the lower receiver. The buffer retainer and bolt stop plunger are made from hardened alloy steel for wear resistance and finished with a phosphate coating to prevent corrosion. Springs are 17-7PH Stainless Steel to prevent corrosion and retain adequate tension for a lifetime of service. Warranty: Covered by BCM’s manufacturer warranty. Warranty service is provided by BCM.
