The Harris No. 2 Adapter Flange Nut is a simple, purpose-built solution for adding a sling stud to hollow plastic fore-ends. The rectangular 5/8" by 1 3/8" flange spreads load across thin walls, while the 5/16" shank with 10-32 threaded hole securely anchors the included stud and washer. The large-headed flange nut is designed to reinforce the mounting point, helping prevent pull-through or damage on lightweight synthetic stocks.

This adapter is ideal for shooters who need a reliable sling or bipod attachment on fore-ends that cannot accept a traditional wood screw stud. Once installed, it provides a stable mounting interface for Harris bipods or standard sling swivels, making it well suited for range use, hunting, and general training. The straightforward design reflects Harris’s long-standing reputation for practical, durable accessories that simply work.
