Description
The Mesa Tactical SureShell brings everything that makes side saddles useful to your Benelli M4 without overcomplicating things. Instead of replacing trigger pins or making permanent changes, this carrier uses the M4's factory receiver holes, so installation is straightforward and reversible if you need it to be.
What sets this system apart is the practical engineering underneath. The shell holders are injection-molded from glass-filled polymer paired with a lightweight aluminum backing plate that has brass threaded inserts. That combination keeps weight down while maintaining real durability. The dual rubber friction system does the actual work of keeping shells in place, and it's sized right so you can load shells either brass-up or brass-down depending on your reloading preference. Mesa includes both a black tube for standard retention and a white tube for stronger hold, so you can dial in what works best for your technique.
Integrated Picatinny Rail for Optics
The 5.5-inch Picatinny rail machined from 6061-T6 aluminum gives you a legit mounting platform for red dots, magnified optics, or other accessories without losing sight picture. It's mil-spec hard-anodized for a non-glare finish that holds up to the kind of use that separates quality from consumer-grade plastic.
Six-Round Capacity That Stays Put
Six rounds on the side of the receiver gives you meaningful reload capacity without bulk or unnecessary weight. Users consistently report that shells stay secure during movement and recoil, which matters whether you're running drills or working through a real scenario. The adhesive-backed rubber gasket included in the box protects your M4's finish from vibration and contact.

Frequently Asked Questions
Will this SureShell work with Benelli M4 clones?
This model is designed for original Benelli M4 and M1014 shotguns. Most clones use different receiver threading (Metric M4 x 0.7 instead of SAE #8-40), so compatibility isn't guaranteed. Check your clone's receiver specs before purchasing, or contact Mesa Tactical directly to confirm fit on your specific platform.
How do I know which rubber tube to use for shell retention?
The black tube comes installed and works well for most shooters. If you find shells moving too easily or want stronger retention (especially if loading brass-down), swap in the included white tube. Both tubes perform the same function, just with different firmness. You can experiment to find your preference.
Does installation require gunsmithing or any modifications to my M4?
No. The SureShell mounts directly to the receiver using the factory-drilled and tapped holes on top of the M4. You simply remove the factory rail, line up the mounting holes, and install the included hardware. You'll be done in minutes without any permanent changes to your shotgun.
What comes with the SureShell to protect my M4's finish?
The carrier includes an adhesive-backed rubber gasket that sits between the saddle and receiver to prevent vibration marks and contact damage. This is a nice detail that shows Mesa Tactical thinks about the practical side of keeping your gun looking clean after use.
