The HK MR556A1 is a premium semi-automatic rifle developed for civilian users, showcasing its lineage as a direct descendant of the renowned HK416. Built for precision and reliability, it features the HK proprietary gas piston operating system, which eliminates malfunctions common to direct impingement systems by keeping hot carbon fouling out of the receiver area. The rifle includes the HK Modular Rail System (MRS), an ergonomic, free-floating handguard designed for maximum accuracy and modularity with Picatinny rail segments. A cold-hammer-forged, German-made barrel ensures superior accuracy and an extended service life. With high-quality American and German components, ambidextrous safety controls, a two-stage trigger, and adjustable length, the MR556A1 is a top-tier choice for modern sporting rifle enthusiasts looking for excellence in function and design.
