The breacher barrel is ideal for tactical scenarios, while the M-LOK adapter allows for the easy addition of accessories like lights and lasers. The single-piece heat shield provides barrel protection and improves handling during extended use. Its flat-profile trigger ensures a smooth and consistent pull, and the ambi rotary thumb safety makes the shotgun user-friendly for both right- and left-handed shooters.
While the shotgun lacks integrated sights, its drilled and tapped receiver allows for the installation of optics or sighting systems, enhancing its versatility. With a 10+1 capacity and a 2.75-inch chamber, the 590RM is well-suited for home defense, tactical operations, or range practice.
