HECKLER & KOCH MR556 A4

HK MR556A4 is as close as you can realistically get to 416 territory in a civilian-legal package—same vibe, same bombproof HK build, and the same “this thing was meant to be run hard” feel when you shoulder it and work the controls. You’re getting that proven HK piston-driven reliability, stout receiver set, and premium fit/finish that people chase the 416 for in the first place. This one’s already set up right with a Geissele MR556-specific trigger and a Radian Raptor charging handle, and it includes the original soft case and paperwork.

All the 416 energy, none of the compromise.
