The UTG MT-RM870 transforms standard Remington 870 shotguns into precision platforms by providing a stable mounting solution for red dot sights, scopes, and tactical optics. This aluminum rail system replaces the factory rear sight to create an elevated Picatinny platform without permanent modifications to the firearm.
What Makes This Different
Unlike universal shotgun mounts that require drilling or gunsmithing, the MT-RM870 utilizes the existing rear sight dovetail for secure attachment. The elevated design positions optics at the optimal height for comfortable cheek weld while maintaining co-witness capability with front bead sights. Aircraft-grade aluminum construction handles recoil forces that destroy lesser polymer mounts.Key Features
