Southfield, Michigan — In the thundering conclusion of Ballistic’s Best 2025 AR-15 category, the rifle that emerged victorious is the Heckler & Koch MR556 A4. After a grueling lineup of eight rifles, ranging in price from just $500 to more than $4,300, only one managed to edge out the rest by a razor-thin margin.

In a competition where ambidextrous controls, ergonomics, precision, and value were paramount, the HK MR556 A4 stood out. Our judging panel, a balanced group of seasoned instructors, hobbyist shooters, and competitive marksmen, evaluated each rifle across nine critical criteria including aesthetics, ergonomics, trigger, recoil, reloading ease, accuracy, reliability, value, and overall handling.

The MR556 A4 earned praise across the board for its fully ambidextrous controls, its adaptability, top-tier craftsmanship, and stellar shooting performance under realistic conditions.

Key to its win was the rifle’s short-stroke gas piston operating system, which significantly reduces hot carbon fouling compared to traditional direct-impingement designs, enhancing reliability and reducing maintenance needs. An adjustable gas regulator allows smooth transition between suppressed and unsuppressed shooting, while the slim, balanced profile makes it feel surprisingly light for a piston-driven rifle.

For shooters who demand top-tier performance without compromise; whether for competition, training, or duty use, the MR556 A4 has earned its place as Ballistic’s Best AR-15 champion for 2025.
