Description
The SureShell Carrier from Mesa Tactical is a straightforward way to carry extra ammo right on your Mossberg 500, 590, or Maverick 88. It mounts to the left side of the receiver and keeps six shells within arm's reach when you need them most. The design uses glass-filled polymer shell holders paired with a lightweight aircraft-grade aluminum back plate and brass threaded inserts, giving you durability without the weight. Installation requires no gunsmithing or permanent changes to your shotgun.
What Makes the SureShell Retention System Work
The key feature here is the dual rubber friction system. It uses elastomer material that grips the shells firmly enough to keep them from shifting or bouncing loose during use, but not so tight that you struggle to pull them out when reloading. The carrier ships with black rubber for general use, and includes harder white rubber replacements for specialty shells or if you prefer a different feel. Shells load and unload from the top, or you can load from the bottom if you prefer that method. Some users find that twisting shells out slightly makes removal smoother with practice.
Installation and Compatibility
The mounting system uses your receiver's existing trigger group pin holes, secured with a lightweight aluminum bracket and hardware. All fasteners and tools come included, so you can have this mounted in under an hour. The 590R model isn't compatible due to design changes on that platform, but standard 500 and 590 shotguns work without issues. One thing to check before ordering: factory field-style forends sometimes overlap the receiver when the bolt pulls back. If that's your setup, you'll need a tactical-style forend or will need to modify your current one.
Build Quality You Can Depend On
Mesa Tactical makes everything in the USA and backs it with a lifetime warranty. The aluminum components are aircraft-grade material with a hardcoat anodized finish that resists rust and wear. This carrier is a proven design that's been trusted by folks in the field for years. Whether you're running tactical training, home defense drills, or just want dependable ammo storage on your gun, this SureShell setup delivers.

Frequently Asked Questions
Do I need to modify my shotgun to install the SureShell Carrier?
No gunsmithing is required. The carrier mounts to your receiver using the existing trigger group pin holes with included hardware. However, if your shotgun has a factory field-style forend that overlaps the receiver, you may need to use a tactical-style forend instead.
How hard is it to remove shells from the SureShell Carrier?
The rubber friction system holds shells firmly without being difficult to retrieve. With practice, many users find that twisting shells slightly as they pull them out makes the process smoother and faster. The carrier comes with black rubber installed for general use, and includes white rubber replacements if you prefer less or more retention.
Will the SureShell Carrier work on a Mossberg 590R?
No, this model is not compatible with the Mossberg 590R due to design changes on that platform. Standard 500 and 590 shotguns work without issues, as do Maverick 88 shotguns.
What makes the polymer version different from Mesa Tactical's aluminum carriers?
This model uses a glass-filled polymer shell holder paired with an aircraft-grade aluminum back plate, making it lighter and more affordable than full aluminum carriers while maintaining the same reliable dual rubber friction retention system. It's made in the USA and backed by Mesa Tactical's lifetime warranty.
