LMT MWS .308/7.62 Semi-Auto Bolt Carrier Group

This Lewis Machine and Tool bolt carrier group is designed for long term durability and reliability.

The R-LM308D is the perfect BCG for your LMT MRP-H or AR10 rifle from sub-par equipment. LMT Defense has made bolt carrier groups and their components and replacement parts for the United States and its allies for years. These BCGs are standard equipment in all of our complete MWS and MARS-H weapons. Works well with both suppressed and unsuppressed weapons.

The gas key has been properly staked to prevent the hardened screws from backing out over time.


  • Enhanced finish
  • Properly staked gas key
  • Hardened gas key screws
  • Made in the USA
