HECKLER & KOCH MR556 A1 5.56

A direct descendant of the HK416, the HK MR556A1 is a premium semi-automatic rifle engineered by Heckler & Koch for the commercial market, offering exceptional reliability, accuracy, and match-grade performance. Featuring HK’s proprietary short-stroke gas piston operating system, the MR556A1 delivers enhanced durability and cleaner operation compared to traditional direct-impingement AR-platform rifles.

This example is an extremely rare Tungsten Grey edition, one of only 100 rifles produced, making it a highly desirable collector’s piece and a standout addition to any advanced firearms collection.
