SP A-0010 RMR Footprint Adapter Plate for ISMS Mount

SP A-0010 RMR Footprint Adapter Plate for ISMS Mount

The SP A-0010 RMR Footprint Adapter Plate for ISMS Mount is designed for the SP ISMS — Ideal Scope Mount System interface. It allows users to mount an RMR-footprint red dot sight onto compatible SP ISMS scope mounts, creating a clean, modular, and highly flexible secondary aiming setup.

The SP ISMS interface is one of the most practical innovations in modern scope mount design. Instead of being limited to one fixed mounting position, users can install their red dot at different angles according to their actual shooting needs, including 90-degree, 45-degree, and top-mounted positions.

Whether you want a top-mounted red dot for fast close-range aiming, a 45-degree offset red dot for quick transitions, or a side-mounted auxiliary optic, the SP A-0010 adapter gives you more freedom to build your optic system your way.

The adapter can be installed toward the front or rear of the SP scope mount, depending on your rifle setup, eye position, accessory layout, and personal shooting preference. It is an excellent choice for LPVO + red dot configurations, tactical training rifles, airsoft builds, and competition-style setups.

Made from aviation-grade aluminum, the SP A-0010 adapter is lightweight, durable, and built for reliable mounting performance. Mounting screws are included, making installation easier and more convenient.
