TacStar Stock Adapter for Mossberg 500

• AR-style stock conversion: This adapter lets a Mossberg 500 accept AR-15 type telescoping stocks and pistol grips, making it easier to tailor fit, handling and control to different shooting roles.
• Die cast metal construction: Built from tough die cast metal alloy rather than a basic polymer body, it adds strength at the receiver junction and contributes extra weight that helps soften felt recoil.
• Proper sight alignment: The adapter is shaped for the proper drop to work with bead or ghost ring sights, so the shotgun remains practical with common sighting setups after the conversion.
• Receiver-matched fit: Its form is designed to match factory receiver contours and mount cleanly, giving the shotgun a more integrated fit instead of a bulky add-on feel.
• QD sling attachment ports: Quick-detach sling ports on both sides make it easier to configure the shotgun for carry and transitions, whether the setup is intended for field use or defensive handling.

About the TacStar Accessories Series

TacStar Accessories is a firearm-accessory range built around practical upgrades for hunters, military professionals and law-enforcement users. The series sits in the part of the market focused on functional shotgun and rifle enhancements rather than cosmetic add-ons, with products such as shell carriers, grips, rails, slings and brass catchers. A defining part of the line is its emphasis on straightforward installation and purpose-built handling improvements for working firearms.

Within the series, TacStar products are known for addressing common use cases such as faster ammunition access, improved weapon control, better sling integration and more adaptable furniture layouts. The range includes the brand’s well-known SideSaddle concept as well as stock, grip and mounting solutions for popular shotgun platforms. That makes the series especially relevant to shooters who want to adapt a standard firearm to a more specialized role, whether for hunting, training or duty-oriented use, while keeping the focus on robust, field-practical hardware.

About the TacStar Stock Adapter for Mossberg 500

The TacStar Stock Adapter for Mossberg 500 is a compact conversion part that changes the shotgun’s rear interface so it can use AR-15 type telescoping stocks and compatible pistol grips. In practical terms, that opens the door to a more adjustable setup than a fixed factory stock, which is useful when the shotgun needs to be configured for different clothing layers, shooting positions or storage constraints. For a platform as widely used as the Mossberg 500, that flexibility can make the gun easier to tune for defensive, training or field applications.

One of the most important design points is the adapter’s die cast metal alloy construction. Compared with lighter polymer-only alternatives, the metal body gives the connection area more rigidity and also adds some rear weight, which can help reduce the sharpness of recoil impulse. The shape is also engineered to follow the shotgun’s factory receiver contours, so the installation looks and feels more integrated on the gun.

This adapter is also designed with the proper drop for bead or ghost ring sights, which matters because stock conversions can otherwise compromise sight alignment. In addition, QD sling attachment ports on both sides make it easier to set up a practical carry arrangement. The adapter accepts standard AR-15 grips without a beavertail, or models with a flexible rubber beavertail, giving the user a broad choice of grip styles. It does not include a buffer tube or stock, which allows the shotgun to be built around the preferred furniture setup.

About TacStar

TacStar is a firearm-accessory brand within the Lyman portfolio and became part of Lyman in 1997 as the company expanded further into tactical and law-enforcement-oriented equipment. The brand focuses on practical accessories for shotguns and rifles, including front and rear grips, magazine extensions, weapon-light systems, slings, rail mounts and brass catchers. TacStar is especially well known for its patented SideSaddle, a shotgun shell carrier that became one of the brand’s signature products.

The company’s reputation in this category comes from designing accessories for real working use by hunters, military personnel and law-enforcement professionals. That background is reflected in products that emphasize straightforward installation, durable materials and functional handling improvements rather than unnecessary complexity. For shotgun parts and furniture upgrades in particular, TacStar remains closely associated with adaptable, use-driven designs for common pump-action platforms.
