Introducing the Next Generation of Optic Enhancement
MK Machining has officially unveiled its groundbreaking Modular Scope Accessory Chassis (MSAC), a cutting-edge optic enhancement system engineered to transform shooting performance across competitive, hunting, and tactical environments.
This innovative platform represents a paradigm shift in scope accessory design, offering shooters an intelligent solution that optimizes maintube utility while conserving critical mounting space for additional equipment. The MSAC delivers a perfect balance of functionality and efficiency, ensuring every component serves a purpose without compromising your rifle's configuration.

Premium Construction and Materials
Aerospace-Grade Durability
The MSAC features precision machining from high-quality 6061 Aluminum, enhanced with a Type III hard coat anodized finish. This construction methodology delivers exceptional durability while maintaining an incredibly lightweight profile of just 1.76 oz (50 grams) without hardware components.
Universal Shooter Compatibility
Engineered with complete ambidextrous functionality, the MSAC seamlessly accommodates both right-handed and left-handed shooters. This universal design philosophy ensures optimal bubble level visibility and enhanced riflescope setting clarity regardless of shooting preference or dominant eye configuration.

Comprehensive Feature Set
Advanced Modular Architecture
The MSAC's revolutionary modular design enables effortless mounting, removal, and repositioning of accessories including the Level Module and Lens Modules. This forward-thinking approach provides expandability for future add-ons, ensuring your shooting system evolves with advancing technology and changing requirements.
