Videos tagged with LMT Enhanced BCG

This video provides an abbreviated physical inspection and custom modification of an LMT Enhanced Bolt Carrier Group. The instructor highlights customer-requested modifications, including dimpling the cam pin and upgrading screws on the carrier key with Michigan Ox and deep golf ball staking. Polishing the carrier key mouth and the back of the carrier are also demonstrated to improve function and prevent buffer wear.

This live Q&A session from Small Arms Solutions covers a wide range of firearms topics. The instructor discusses the internal components of bolt carrier groups, the historical quality issues with Olympic Arms, and the differences between stainless steel and chrome-lined barrels. He also touches on the manufacturing practices of various AR-15 manufacturers like DPMS, Bushmaster, and Saber Defense, the pros and cons of different buffer systems, and recommendations for AR-15 optics. The discussion extends to the military's potential adoption of new combat rifles, the reliability of DPMS firearms, and the design philosophy behind Glock's grip angle. Additionally, the instructor addresses questions about specific calibers like 6.5 Grendel and 6.8 SPC, the effectiveness of Black Hills ammunition, and the best rifle for an apocalyptic scenario.

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.
