Geissele Super Duty 12.5-inch Duty SBR on a Griffin MK2 Lower

A duty rifle built by a new police officer whose department requires officers to supply their own: a Geissele 12.5-inch Super Duty complete upper on a Griffin MK2 ambidextrous lower. An Aimpoint T2 on a Unity riser pairs with an EOTech M33 magnifier in a Unity flip mount, and a SureFire M640 Turbo runs a Unity Gascap with a tape switch. A B&T Print-XH RBS SC mounts on a Rearden Atlas Gen 2 and SPB brake, and Forward Controls Design supplies the safety, pins and hard-use small parts.
