MSAC Modular Scope Accessory Chassis

The MK Machining MSAC (Modular Scope Accessory Chassis) is a modular turret magnifier and scope level system that combines multiple optic accessories on one compact, precision-machined chassis. Instead of stacking independent accessories across your scope tube, the MSAC uses interchangeable Lens and Level Modules while preserving valuable maintube space.

Designed for competitors, long-range shooters, and hunters who regularly dial their optic, the MSAC makes small turret markings easier to read while providing the option for an integrated anti-cant reference. Its modular design lets you configure the system around your setup rather than being locked into a fixed accessory arrangement.

Clearer Turret Readings

MSAC Lens Modules can be positioned to magnify both elevation and windage turret markings, giving you a clearer view of the adjustments you reference most. Each lens provides approximately 2–3× magnification depending on its distance from the turret, with roughly 2–3 inches of spacing recommended for optimal viewing. The scratch-resistant acrylic lenses are built for repeated field and range use, and multiple Lens Modules can be positioned at equal distances for consistent magnification across both turrets.

Integrated Scope Leveling

The MSAC Level Module brings the proven XLP-style level design directly to the chassis, using the same highly visible vial and windowed housing concept for clear viewing from multiple angles. Rather than adding a separate scope-mounted level, the module integrates directly into the MSAC system, preserving maintube space while keeping an anti-cant reference easy to see.

Modular by Design

Lens and Level Modules can be added, removed, or repositioned to configure the MSAC around your setup. The modular chassis also provides a platform for future MSAC accessories, allowing the system to evolve as your needs change.

Precision-Machined Construction

The MSAC chassis is precision-machined from 6061 aluminum and finished with a Type III hardcoat for lightweight durability and a rigid mounting platform. The complete system weighs just 1.76 oz (50 g) with hardware and features an ambidextrous design suited for both right- and left-handed shooters.
