Benefits & Use Cases

The No. 4 adapter is the go-to solution for older sporting rifles, vintage firearms, or entry-level models that do not feature a sling swivel stud. By clamping directly to the barrel, it provides a functional attachment point for any Harris bipod, allowing you to benefit from a supported rest in the field. This is particularly useful for hunters who need a quick, non-permanent way to add a bipod to a variety of different rifles in their collection.

The two-piece design ensures an even distribution of pressure around the barrel, preventing movement while maintaining the structural integrity of the firearm. It is a rugged, field-proven tool for those who prioritize portability and ease of installation. Whether you are shooting at the range or glassing in the backcountry, the No. 4 gives you the flexibility to add a rock-solid rest to almost any thin-to-medium profile barrel.
