TacStar 1081029 SideSaddle Rail Mount 12 Gauge 6-Rd Shotshell Carrier - Mossberg 500/590

The TacStar 1081029 SideSaddle Rail Mount is a dedicated shotshell carrier purpose-built for 12 Gauge Mossberg 500 and 590 shotguns. This ultra-rigid, lightweight aluminum unit straddles both sides of the receiver, keeping six (6) extra rounds immediately accessible without requiring the shooter to break their firing grip.

The integrated SideSaddle shell carrier is molded from flexible synthetic rubber, securely gripping six 12 Gauge shells along the length of the receiver for fast, snag-free reloads in defensive and utility applications. The mounting bracket carries a hardcoat anodized black finish for long-term durability and corrosion resistance in the field.

Engineered specifically for the Mossberg 500 and 590 receiver profile, this SideSaddle Rail Mount installs directly to the receiver and places six rounds right at the shooter's fingertips, making it a practical upgrade for any tactical or sporting shotgun in that family.
