Original British WWII Bren LMG MkII Bolt Carrier and Gas Piston Assembly 21st Century 577/450 Martini-HenryOriginal Item: From our recent importation of Bren parts, these are complete bolt carriers with attached gas pistons, or operating rods. This item helps to capture the energy from the gas recoil system, and cycles the bolt.
