TacStar 1081159 SideSaddle Mossberg 500/590 12 Gauge 6-Round Shell Holder

The TacStar 1081159 SideSaddle transforms any Mossberg 500 or 590 into a tactical powerhouse with instant access to six additional 12-gauge shells. This receiver-mounted shell carrier eliminates fumbling for ammunition during critical moments, keeping rounds secure and accessible exactly when needed.

What Makes This Different

Unlike fabric shell holders that sag or elastic carriers that lose tension, the TacStar SideSaddle features a rigid polymer construction with individual shell retention grooves. The aluminum mounting plate distributes stress across the receiver, preventing flex under recoil that can cause shells to work loose. Each shell sits in a precisely molded channel that holds rounds firmly yet allows rapid extraction with thumb or finger pressure.

Key Features

• Holds six 2¾-inch or 3-inch 12-gauge shells in individual retention grooves
• Durable black polymer construction with corrosion-resistant aluminum mounting plate
• Mounts directly to Mossberg 500/590 receiver without gunsmithing
• Low-profile design maintains proper cheek weld and sight alignment
• Ambidextrous shell access accommodates both right and left-handed shooters
• Weather-resistant polymer withstands temperature extremes and moisture
• Compatible with standard and tactical Mossberg 500/590 configurations

The SideSaddle proves invaluable across multiple applications, from competitive 3-gun matches where speed reloads determine placement to law enforcement scenarios requiring immediate ammunition access. Home defense users benefit from having backup shells instantly available without searching for boxes or loose rounds. The secure retention system prevents shells from rattling or falling out during movement, while the smooth polymer surface won't snag on clothing or gear.
