FN Five-seveN MRD 5.7×28 | 4.8 in | 66101276

The FN Five-seveN MRD is an optics-ready, semi-automatic pistol chambered for the 5.7×28 mm cartridge and built on a lightweight polymer frame. The MRD platform uses a plate-based mounting system that accepts multiple common optic footprints, allowing rapid installation of a compatible micro red dot. For an optic under $1,000 that pairs well with this pistol, consider a Holosun 507K micro red dot for a low-profile, co-witness setup. Typical applications for this handgun include everyday carry for users who choose a compact, high-capacity pistol and target/practical shooting where low recoil and flat trajectories are valued.
