Mark 4 6.5-20x50mm Extended Range/Tactical (ER/T) M5 Auto-Locking Adjustment Model

Leupold’s focus on product development has culminated in a new generation of tactical riflescopes that cover the entire spectrum of optics requirements, from close quarters to extended ranges, for warfighters as well as law enforcement and competitive shooters.

The Leupold Tactical Optics Division has launched innovative riflescopes including the Mark 4 6.5-20x50mm Extended Range/Tactical (ER/T) M5 Auto-Locking Adjustment model. The U.S. Army has chosen the ER/T M5 Auto-Locking Adjustment riflescope as the primary day optic for its newest sniper rifle, the XM2010. In addition, Leupold recently contracted with the United States Marine Corps (USMC) to supply the CQBSS for use with M2 heavy machine guns and MK19 grenade machine guns. The Marine Corps sight will carry the M521 designation.

The ER/T Auto-Locking Adjustment riflescope is specially designed and built with the military sniper in mind. It has an auto-locking elevation adjustment. This feature ensures that reticle adjustment is maintained during rough going and stressful conditions. Reticle options include the Horus H27 and H58, as well as Leupold’s Tactical Milling Reticle (TMR).
