The TacStar SideSaddle Mossberg 500 20 gauge 4-round carrier is a practical shotgun shell holder that bolts to the receiver of your 500, keeping extra ammo within arm's reach during the hunt. Instead of fumbling through jacket pockets or a pouch when you need to reload, a side-mounted carrier gives you quick access to rounds exactly where you need them. The design mounts without any modification to your shotgun, making it a straightforward add-on for hunters and clay shooters who want faster follow-up shots.
Built from tough polymer and backed by an aluminum plate, this carrier is engineered to withstand field use while resisting corrosion. The mounting hardware is included, and the design clears longer forends so you won't have fitment headaches common with some aftermarket shotgun accessories. If you run a Mossberg 500 in 20 gauge and want your reload rounds organized and instantly accessible, this is a no-fuss upgrade.
The SideSaddle concept is simple but effective: four rounds live on the side of the receiver, balanced and stable, ready to feed into the magazine when needed. Whether you're hunting waterfowl, upland game, or running a shotgun course at the range, having ammo staged properly beats patting pockets or managing a separate carrier.
