LWRC Advanced Bolt Carrier Group AR-15 223 Remington, 5.56x45mm Nickel Boron

In response to the US ARMY’s requirement for improvements to the M4 Carbine, LWRC International designed and developed the Advanced Bolt Carrier Group which offers a significant capability advantage when installed in a host M4. The Advanced Direct Impingement Bolt Carrier Group offers superior performance, increased reliability, and longer part replacement life cycles than the MIL-STD components. These gains are achieved through LWRCI’s design technology paired with industry-leading machining and material technology. In testing, the LWRC International Advanced Direct Impingement Bolt Carrier Group exhibited remarkable performance, running over 10,000 rounds without stoppage or failure on a host weapon that was neither cleaned nor lubricated during the testing process.
