The ATI Outdoors Shotforce RPG is an AR-style rear pistol grip purpose-built for shooters running Mossberg, Remington, Winchester, and Maverick pump shotguns who want more control and comfort behind the gun. If you've shot a tactical shotgun with the factory grip and thought there had to be a better way to manage recoil and stay locked in on target, this grip delivers the ergonomic upgrade your shotgun needs. The slim, ergonomic design fits naturally in your hand whether you're running 12-gauge or 20-gauge loads, and the textured surface keeps your grip consistent even under stress or when wearing gloves.
This is a true AR-pattern grip, so if you're already familiar with running an AR platform, the controls and feel will be instantly intuitive. The top-mounted sling loop integrates seamlessly into your setup, and installation is straightforward—the package includes all necessary adapters and mounting hardware for whatever Mossberg 500/535/590/835, Remington 870, Winchester 1200/1300, Maverick 88, or American Tactical MB3 platform you're working with. No gunsmithing required.
Built from DuPont Extreme Temperature Glass Reinforced Polymer, the Shotforce RPG is engineered to handle heavy use and brutal weather. It's made in the USA, so you're supporting domestic manufacturing while getting a grip that won't let you down in the field or on the range.
