Overview

This rail adapter provides a Picatinny attachment point for Atlas bipods on compatible stocks, giving hunters a straightforward way to set up a stable support interface. The 3.35-inch version is sized for hole patterns with 1.76-inch to 2.78-inch center-to-center spacing and is designed to fit curved surfaces. It mounts to the stock using either a sling stud and spacer or machine screws, both not included, so installation depends on the hardware already on hand. For rifles that need a dedicated bipod mounting point without unnecessary bulk, it offers a practical, purpose-built option.
