The Talley RMR870 is a precision-machined direct mount for RMR-footprint red dots on your Remington 870 shotgun. Built from 6000-series aluminum and hard-coat anodized to 65 Rockwell hardness, this American-made base eliminates the need for a separate picatinny rail or adapter, giving you a clean, minimal platform for fast-acquiring optics on your tactical or hunting 870. It's engineered for the tightest tolerances in the industry and weighs considerably less than rail-based alternatives.
Whether you're setting up a turkey gun with a dot sight or upgrading a defensive shotgun, the RMR870 keeps your sight line low and your rig light. The mount uses the two rearmost holes on the 870 receiver, so installation is straightforward—no gunsmithing required. You get the mounting screws and wrench in the box, so you're ready to bolt it on.
Talley Manufacturing's reputation rests on precision and durability, and this mount reflects that. The aluminum construction won't rust or corrode, and the hard-coat anodizing will stand up to years of use. If you're running an RMR, Holosun HS507K, or any red dot with the RMR footprint, this is a direct fit.
