This video provides a detailed comparison between a standard GI AR-15 bolt carrier group (BCG) and LMT's enhanced BCG. It highlights design differences aimed at improving dwell time, gas management, extraction reliability, and overall component longevity. The enhanced BCG features altered cam path angles, modified gas ports, reduced friction surfaces, and a stronger bolt lug design made from proprietary metal, all contributing to potentially smoother operation and increased durability.
