This matched front and rear sight set delivers rapid target acquisition with a dual-aperture rear sight (large and precision apertures) and a protected front sight post optimized for 7.62 NATO ballistics. Spring-loaded folding mechanisms allow seamless co-witnessing with optics while maintaining zero when deployed.\u003c\/p\u003e\u003cp\u003eConstructed from hardened steel with a low-profile design, the C4 combo mounts to standard Picatinny rails and features tool-free windage and elevation adjustments.
