Lantac 223/5.56 E-BCG TiN Full Auto Style Bolt Carrier Group for Semi Auto

The Lantac 223/5.56 E-BCG Full Auto Style Bolt Carrier Group in TiN is precision engineered to deliver smoother operation, cooler temps, and enhanced accuracy for both semi-auto and full-auto rifles. Machined from 8620 steel with a shot-peened Carpenter 158 MPI bolt and fully TiN-coated surfaces, this carrier features Lantac's patented shrouded and forward-facing gas ports that vent gas differently to promote a flatter recoil impulse and a cleaner, cooler system, especially when running suppressed barrels. The flared tail boss enhances lockup within the upper for repeatable accuracy, while hard-turned and ground critical dimensions and a hard chrome-lined gas key maximize wear resistance. The CP-R360 domed cam pin, machined from 17-4PH stainless steel and hardened to H900, delivers ultra-smooth head contact to reduce wear in the upper receiver, and a balanced 11.7-ounce weight helps improve lock time and overall cycle feel. Forward porting and enlarged vents aid in reducing pressurization inside the upper, a benefit for short-barrel rifles and suppressed setups, though results can vary by weapon. All components meet Mil-Spec standards with hard chrome surfaces to MIL-STD-171, and the entire assembly is designed for durability, reliability, and consistent performance in demanding shooting scenarios.
