Leupold’s® Tactical Optics Division has won a contract with the United States Marine Corps (USMC) to supply 728 Mark 8™ 1.1-8x24mm CQBSS™ riflescopes for use with M2 heavy machine guns and MK19 grenade machine guns. The sight will carry the M521 designation.

Ordered to meet the need of Afghanistan-based Marine units for a Heavy Day Optic, the Mark 8 CQBSS scopes will be employed to support combat operations. A key feature of the scope is Leupold’s new Marine-Tactical Milling Reticle (M-TMR™), which is designed to allow successful range estimation and target engagement with more flexibility than generally possible with other reticle styles. The M-TMR’s ‘staircased’ configuration preserves the instinctive-fire capabilities on low magnification while allowing precise range estimation at any power setting.

“The Marine Corps’ innovative employment of this new technology will bring enhanced lethality to two combat-proven systems, the M2 and MK19 heavy machine guns,” said Kevin Trepa, vice president of Leupold’s Tactical Division. “We will continue working hard to deliver the new tools that our warfighters need to succeed on the battlefield.”

The Mark 8 CQBSS has a state-of-the-art lens system providing operators with the capability of an 8-power precision riflescope in one rugged, field-proven unit. The 34mm maintube features a fully checkered ocular bell for making quick magnification adjustments even while wearing gloves.

A front focal plane reticle, the M-TMR is accurate at all magnification settings. Eight illumination settings allow for optimum contrast with or without night vision. An off position between each intensity setting makes returning to the preferred setting nearly immediate.

In addition, the Mark 8 CQBSS has Auto-Locking Pinch and Turn turrets with 0.10mm clicks that are extremely easy to adjust, yet eliminate accidental adjustment in the field. Leupold’s Index Matched Lens System® with DiamondCoat 2™ helps enhance optical performance by providing increased light transmission and scratch resistance that exceeds mil-specs.

Mark 8 CQBSS riflescopes have a matte black finish and are filled with an argon/krypton gas blend, making them second-generation waterproof, fog proof and shock proof. Flip-open lens covers and a 2.5in sun shade are standard issue.
