Outdoor Connection BO5 Swivel Base Set - Black Steel, Includes 7/8" McScrew, 1/2" & 3/4" Wood Screw Base, 3 Spacers

The Outdoor Connection BO5 Swivel Base Set gives you a straightforward way to upgrade your rifle's sling attachment. If your firearm came with a fixed swivel base or you want to replace a worn one, this black steel setup accepts any standard U.S. detachable swivel—letting you swap between sling styles or remove your sling entirely without tools. The machined construction delivers a clean, purposeful look that fits rifles from classic bolt-actions to modern sporting rifles.

This kit includes everything you need for a typical installation: a 7/8" McScrew base, both 1/2" and 3/4" wood screw bases to match your stock, and three spacers to fine-tune fit and clearance. That variety means you're covered whether you're mounting to a modern tactical stock or a traditional wood furniture setup. Black steel construction is durable and corrosion-resistant enough for field use, though it will develop a natural patina over time—part of the appeal for hunters and shooters who prefer working gear over showroom shine.

Whether you're outfitting a new hunting rifle, refreshing an older firearm, or simply want the flexibility of swapping slings on demand, the BO5 gives you the hardware foundation to do it right. Installation is straightforward for anyone comfortable with basic gunsmithing, and the detachable swivel system means your sling setup can evolve with your needs.
