FAQ

Is the MRD (MK3) the newest Five-seveN model?
Yes — the MRD (MK3) is the latest generation, offering an optics-ready slide and enhanced ergonomics over the MKII.

Can I mount a red dot directly?
Check compatibility first: Make sure your optic matches one of the included plates. Then follow the manual’s installation steps and torque specs for a secure mount.

Is the MRD suppressor-ready?
No — but dropping in an EFK threaded barrel makes suppression possible with no fitting required.

Is the MRD heavier than the MKII?
Yes — at 25.2 oz unloaded, the MRD is slightly heavier, which helps reduce felt recoil and improve control for rapid follow-up shots.
