Key Features

• Precision-machined 8620 steel carrier with M16 full-auto profile for added mass and improved lock time
• Shot-peened Carpenter 158 or 9310 bolt, magnetically particle inspected for maximum strength and reliability
• QPQ nitride finish provides exceptional corrosion resistance, wear protection, and a low-friction surface
• Forward-facing shrouded gas ports redirect expanding gases away from the shooter and upper receiver for cleaner, cooler operation
• CP-R360 domed cam pin machined from hardened 17-4PH stainless steel reduces wear and ensures smooth cam engagement
• Hard chrome-lined gas key staked at four points with Grade 8 fasteners for secure, long-lasting performance

Why Choose This Product

Standard BCGs often direct excess gas back into the upper receiver, leading to increased fouling and shooter discomfort—especially with suppressors. The Lantac E-BCG solves this with its patented porting design that vents gas forward through the ejection port. The added carrier mass promotes consistent lock time and a flatter shooting experience, while the durable nitride coating makes cleaning quick and simple. Every critical dimension is hard-turned and ground after heat treatment for precise fit and function.
