The tactical shooter who values reliable reload options and a clean, unobtrusive accessory footprint will appreciate a well-executed sidesaddle. This mount improves readiness without compromising the shotgun’s sight picture or handling characteristics.
TACSTAR SIDESADDLE RAIL MOUNT is an ultrarigid, lightweight aluminum unit that straddles both sides of the receiver and features a nonglare anodized finish. The top Picatinny rail sits just high enough to preserve the shotgun’s bead sight, while the integrated Slimline SideSaddle shotshell carrier—made of flexible synthetic rubber—keeps six extra shells immediately accessible. This model fits 12 gauge Mossberg 500 and 590 platforms and is categorized as a Shell Holder. Shop this product

Design and materials
The mount’s ultrarigid aluminum construction keeps weight low while maintaining a rock-solid platform for both the shotshell carrier and any lightweight accessories you choose to add to the Picatinny rail. The nonglare anodized finish reduces reflections in bright conditions—an important detail for tactical and hunting applications.
Slimline carrier and reload ergonomics
The built-in Slimline SideSaddle shotshell carrier uses a flexible synthetic rubber to retain six 12 gauge shells securely, allowing positive removal under stress. Because the rail is positioned to preserve the bead sight, shooters retain quick, instinctive aiming for close-quarters engagements while gaining accessible spare ammunition for follow-up shots.
Fit, compatibility, and price
Made to fit 12 gauge Mossberg 500 and 590 models, this unit is a straightforward upgrade for those platforms. It’s listed at $114.98—an affordable price point for a durable, dual-function mounting solution that combines shell storage with accessory mounting capability. View product details and pricing
Field applications
For home defense, patrol, or range setups, the TACSTAR SIDESADDLE RAIL MOUNT balances ammunition accessibility with the ability to add optics or lights on the Picatinny rail. Its low-rise rail preserves traditional bead use for fast target acquisition at close range, while the six-shell carrier reduces reload time in stressful scenarios.
