EOTech G43 Black on STS Mount

This configuration includes an EOTech G43 3x magnifier in black, paired with the factory STS (Switch-to-Side) mount, which uses a spring-tensioned, push-to-deploy mechanism to transition the magnifier laterally out of the sight line when not in use. The STS mount positions the magnifier at standard height-over-bore, compatible with both absolute and lower 1/3 co-witness optics. Lockup is secure, and deployment is controlled via a push-pivot system with no secondary latches.

The G43 offers a smaller, lighter alternative to the G33, with a 3x fixed magnification, 2.5-inch eye relief, and 7.5° field of view. Windage and elevation are user-adjustable in 0.5 MOA increments. The housing is sealed for fog resistance and water resistance to 10 meters. Includes 7mm spacer, no original packaging.
