GG&G Side Saddle Shotshell Carrier Mossberg 590 Shockwave 12 Gauge 5-Round Aluminum Black

The GG&G Mossberg 590 Shockwave 12 gauge 5-round aluminum side saddle shotshell carrier is a fast-access ammo holder designed for shooters who need quick reloads without fumbling. Built for the Mossberg Shockwave platform, this shell carrier mounts directly to your receiver with no gunsmithing required, keeping your rounds exactly where you need them during range sessions, dynamic shooting events, or tactical training. Whether you're running drills or working through stages, having five rounds staged and ready beats reaching for loose ammo.

The carrier positions shells at a 15-degree angle that naturally matches your hand position during the reload stroke, cutting down on fumbling and wasted motion. You've got flexibility too: load the shells base-up or base-down depending on your grip style and reloading preference. The 6061 T6 aluminum construction keeps it lightweight without sacrificing durability, and the matte black anodized finish resists corrosion through hard use and storage. At 6.5 inches overall length, it's compact enough to stay out of the way without eating up real estate on your gun.

Installation is straightforward—no permanent modifications to your Shockwave, so you can remove it if you swap guns or need to travel. This model is the base shell holder configuration; GG&G also offers versions with quick-detach sling swivel loops if you want integrated mounting options. Just remember this carrier is purpose-built for the 12 gauge Mossberg Shockwave and won't fit the 20 gauge variant.
