Heckler & Koch MR556 A4 Pistol Features
The MR556 A4 Pistol is built around HK’s proprietary short-stroke gas piston system, which reduces fouling and heat for enhanced reliability and longevity. Its cold hammer-forged barrel delivers outstanding accuracy, while the free-floating handguard offers superior handling and flexibility for mounting optics and accessories.
Designed with user comfort in mind, this pistol features ambidextrous controls, making it accessible for both left and right-handed shooters. Its compact form factor, combined with an optics-ready platform, allows for maximum customization to suit any tactical or defensive application.
