Harris No. 3 Adapter (Remington 4, 74, 7400)

The Harris No. 3 Adapter is the professional solution for mounting a bipod to rifles with flat-bottomed fore-ends. This adapter provides a secure, permanent swivel stud interface for stocks that lack factory-installed hardware, ensuring your bipod remains stable and properly aligned. By utilizing a high-strength internal flange, it reinforces the stock material to handle the pressure of bipod loading and recoil without loosening over time.

Benefits & Use Cases

The No. 3 adapter is specifically engineered for rifles with wide, flat fore-ends where a standard curved swivel stud might sit unevenly. It is the ideal choice for customizing classic sporting rifles or modern flat-bottomed stocks, providing a rock-solid mounting point that won't mar the exterior of your rifle. This adapter allows you to bridge the gap between a traditional stock and a professional-grade Harris bipod, giving you the stability needed for precision field shots.

Because this adapter requires drilling a small hole for the 10-32 thread, it creates a much stronger connection than a simple wood screw. This makes it perfect for heavy-recoiling calibers or rifles that see frequent use in demanding environments. Whether you are upgrading a favorite hunting rifle or building a dedicated precision rig, the No. 3 provides the dependable interface you need for a consistent shooting platform.
