The HK MR556 A4 SBR brings the proven HK416 lineage into a shorter, more compact rifle configuration built for shooters who value hard use capability and unmistakable HK refinement. As the short barreled version of the MR556 A4, it preserves the platform’s military rooted design philosophy while offering a more compact footprint for those drawn to the more specialized side of the HK catalog.
At the core of the MR556 A4 SBR is HK’s short stroke gas piston system, engineered to run cleaner and cooler than direct impingement platforms while reducing internal fouling and wear. Combined with an 11 inch barrel, fully ambidextrous controls, and a free float handguard with full length top rail, the result is a compact rifle that retains the durability, balance, and operating character expected from a true HK firearm.
More than a shortened variant, the MR556 A4 SBR carries a distinct presence of its own. Its compact proportions and factory HK pedigree make it especially appealing to buyers who appreciate purposeful configurations that stand apart from the ordinary.
This configuration ships with one 30 round magazine and remains one of the most desirable modern HK short barreled rifles for those who value reliability, lineage, and collector appeal.
For the enthusiast who wants the HK416 story in a tighter and more specialized package, the MR556 A4 SBR is a standout addition to the modern HK lineup.
