What are the key features of the FN Five-SeveN MRD?
The Preview: FN Five-SeveN MRD builds on the legacy of the original 5.7x28mm pistol with several modern enhancements. The most significant update is the FN Optics Mounting System, allowing for direct attachment of various micro red dot sights. This system is robust and keeps the optic low to the bore, aiding in natural aiming and co-witnessing with the iron sights if desired. The pistol retains its lightweight polymer frame, contributing to its comfortable handling and reduced recoil impulse, especially when compared to larger calibers. The 5.7x28mm cartridge itself offers high velocity and a flat trajectory, making it an interesting option for personal defense and range use. The magazine capacity is generous, with standard 20-round magazines, and 10-round options for compliance in restricted states. The ergonomics are familiar to those who have handled FN pistols, with a comfortable grip and ambidextrous controls. The trigger pull is consistent, aiding in accurate shot placement. For those interested in customization, a threaded barrel option is available for suppressor attachment, expanding the pistol’s utility. The FN Five-SeveN MRD FDE variant offers an alternative aesthetic for those preferring a different finish.
