Description

Heckler and Koch MR556 A4 Pistol with 11 Inch Barrel and One 30 Round Magazine

The HK MR556 A4 Pistol brings the proven HK416 lineage into a compact 5.56 platform built for shooters who want serious capability in a shorter configuration. Designed around HK’s established piston driven system, the MR556 A4 Pistol delivers the same mechanical confidence, durability, and refinement that made the platform so widely respected.

At its core is HK’s short stroke gas piston system, engineered to run cleaner and cooler than traditional direct impingement rifles while reducing fouling and wear on internal components. Paired with an 11 inch barrel, fully ambidextrous controls, and a free float handguard with full length top rail, the MR556 A4 Pistol offers a compact layout without giving up the fit, finish, and operating character expected from a true HK firearm.

This configuration ships with one 30 round magazine and holds a distinct place within the modern HK lineup. Within the MR556 family, the A4 Pistol carries a different kind of appeal: more compact, more specialized, and unmistakably HK.
