The Outdoor Connection Barrel Bolt w/Swivel Base Mossberg 500 12GA & 20GA Black

The Outdoor Connection Barrel Bolt with Swivel Base is a magazine takedown bolt purpose-built for the Mossberg 500 pump-action shotgun. Precision-machined from cold rolled steel with a distinctive knurl pattern, this assembly drops in place of the factory magazine tube cap and adds a front sling swivel attachment point in one component.

The integrated 3/4" wood screw swivel base rotates a full 360 degrees, letting the attached swivel self-align as the shotgun is carried, shouldered, and manipulated. It accepts all standard U.S. detachable swivels and accommodates both internal ratchet and external ball/spring detent systems, making it a direct-fit upgrade for the Mossberg 500-pattern magazine tube without any drilling or gunsmithing.

This barrel bolt is sized for the Mossberg 500 in 12 Gauge and 20 Gauge, and it is also a fit for the 16 Gauge Mossberg 500 magazine tube. It gives pump-shotgun owners a clean, factory-style solution for adding or relocating a sling mount, retaining full magazine tube function while giving the front of the gun a low-profile, knurled, swiveling anchor point.
