CMMG

The MkW was engineered to harness the full potential of the 458 SOCOM cartridge utilizing the powerbolt technology based off the Mk3. The unique MkW lower receiver readily accepts all standard AR15 magazines. Every MkW XBE2 rifle comes equipped with an SLR adjustable gas block to allow for tailoring your rifle to the round you choose to unleash, CMMG-modified Lancer L5-AWM magazine, Magpul furniture, and a Geissele SSA trigger.
