The modern defensive operator needs a rifle that blends battlefield-proven mechanics with user-focused ergonomics. Tactical teams and responsible citizens alike value systems that run clean, are easy to maintain, and can be tuned quickly for different mission profiles. Reliable suppression compatibility, ambidextrous handling, and a durable operating system separate good rifles from the best in this class.

Overview
The HECKLER & KOCH MR556 A4 is HK-USA’s commercial update to the legendary HK416 platform. Designed as a “no compromise” option, the MR556 A4 brings HK’s short-stroke gas piston operating system to the semi-auto market. This piston design keeps hot carbon out of the action, improving reliability and reducing wear compared with direct-impingement AR-style rifles. The package includes a 30rd magazine and is positioned at a retail price of $3499.99. Shop this product to view the full product page and purchase options.
Performance & Maintenance
Short-Stroke Gas Piston
The short-stroke gas piston in the MR556 A4 prevents fouling from cycling back into the receiver, allowing longer sustained fire with reduced cleaning intervals. Operators will notice less heat transfer into internal components and a more consistent recoil impulse under extended use.
Adjustable Gas Regulator
A user-adjustable gas regulator allows quick tuning for suppressed or unsuppressed operation. This capability ensures reliable cycling when adding a suppressor and helps minimize overgassing that can accelerate wear or increase recoil impulse for lightweight builds.
Ergonomics & Controls
Fully ambidextrous controls and a slimmer, lighter profile make the MR556 A4 easier to manipulate under stress. The low-profile ergonomics aid transitions, reloads, and equipment compatibility for a wide range of users and mission sets. Available in various configurations, this model delivers HK’s signature durability in a modern defensive package. View product details and pricing
