TacStar 1081210 SideSaddle 6-Round Shell Carrier Mossberg 500/590

The TacStar 1081210 SideSaddle transforms any Mossberg 500 or 590 shotgun into a rapid-reload platform with six additional 12-gauge shells instantly accessible on the receiver. This slimline design maintains the shotgun's balance while providing critical ammunition capacity for tactical applications.

What Makes This Different

Unlike bulky stock-mounted carriers that shift the gun's center of gravity, the SideSaddle mounts directly to the receiver using a precision-machined aluminum plate. The polymer shell loops flex to accommodate various shell lengths from 2¾" to 3" without binding. This low-profile design adds minimal bulk while keeping shells protected from debris and moisture.

Key Features

• Holds six 12-gauge shells in secure polymer loops on receiver side
• Aluminum mounting plate ensures solid attachment to Mossberg 500/590 series
• Slimline profile adds only 0.75" to receiver width
• Accommodates 2¾", 3", and mixed shell lengths simultaneously
• Ambidextrous design works for left or right-handed shooters
• Black polymer construction resists impact and weather exposure
• Tool-free shell insertion and extraction under stress

Field performance centers on accessibility and retention balance. The shell loops grip firmly enough to prevent loss during movement yet release smoothly when pulled straight out. Competition shooters appreciate the consistent shell positioning for muscle-memory reloads. Law enforcement and home defense users benefit from doubled onboard capacity without magazine modifications. The carrier maintains full ejection port access and doesn't interfere with standard operation.
