The 8620 steel carrier is heat treated, hard turned, and ground, ensuring long-lasting structural integrity and a smooth cycling action under extreme conditions. The bolt is constructed from MPI-tested Carpenter 158 or 9310 steel, and is shot peened, hard turned, and ground to military specifications for exceptional strength and performance. These materials and treatments combine to create a bolt group that functions flawlessly in both semi-automatic and full-automatic fire control groups.
Finished in Titanium Nitride, this BCG provides reduced friction, increased lubricity, and superior corrosion resistance. Proudly made in the USA and backed by a lifetime warranty, the LanTac M-SPEC is a top choice for serious shooters, professional builds, and those who demand dependability from their rifle's core.
