The Griffin Armament MK2 Stripped Lower Receiver (brand part no. MK2ALFDE) is an AR-15 lower receiver machined from 7075-T6 aluminum and finished in Griffin’s Terra Brown hardcoat anodizing, sold stripped and ready to serve as the serialized foundation for a custom build. Griffin Armament cuts the MK2 to tight tolerances with a flared magwell and integrated trigger guard, and the Terra Brown finish resists wear, scuffs, and discoloration from cleaning solvents better than a standard anodized finish. Ambidextrous bolt catch, bolt release, and magazine release controls make it a strong option for shooters who want true left- and right-hand operation on a personal rifle or duty build. It accepts mil-spec lower parts kits, so builders can outfit it with the trigger, grip, and buffer components of their choice.
