FAQ
Is the MKII suppressor-ready from the factory?
No — but adding an EFK threaded barrel is an easy, drop-in upgrade that allows you to run most 5.7×28mm suppressors.
Is the MKII the newest model?
No — the MKII is the refined evolution of the original Five-seveN. The newer MRD (MK3) adds an optics-ready slide and enhanced controls.
Why choose the MKII over the MRD (MK3)?
The MKII is lighter, simpler, and ideal for shooters who prefer adjustable iron sights and a minimalist setup.
