Product Description
The LANTAC USA M-SPEC Bolt Carrier Group (BCG) for 308/7.62mm delivers milspec-grade precision at an accessible price point, making it an ideal choice for budget builds that refuse to compromise on quality or reliability. The full auto-style carrier is built with increased mass and manufactured from 8620 steel, case hardened and hard turned/ground so that all internal dimensions conform to exact military specifications. Rather than standard Type M Phosphate, this BCG receives a Nickel Boron (NiB) coating that greatly enhances corrosion resistance, durability, lubricity, and long-term performance. The bolt is precision machined from Carpenter 158 or 9310 steel, shot peened and hard turned per military specifications to ensure consistent strength and function. Rounding out this premium assembly is the LANTAC CP-R360 domed head cam pin, precision machined from 17-4PH stainless steel, hand polished, and hardened to H900 condition to minimize friction and wear inside the upper receiver. The M-SPEC line is engineered for shooters who demand reliable performance without overspending.
