Description
The Mesa Tactical SureShell AL RMR combines two essential shotgun upgrades into one integrated package. You get a reliable shell carrier for your Beretta 1301 plus a dedicated mount for RMR-footprint reflex sights, all machined from aircraft-grade 6061-T6 aluminum. This isn't some add-on rail with an aftermarket clamp. It's a precision-engineered carrier that attaches directly via the factory drilled and tapped receiver holes on top of your 1301, making the whole setup clean and permanent.
What sets the SureShell AL RMR apart
The defining feature here is the integrated RMR mount that co-witnesses with your shotgun's factory ghost ring sights. You mount your reflex optic directly to the carrier itself rather than buying a separate rail system. This design approach has become the standard for many law enforcement agencies because it keeps the sight picture intact while adding a modern red dot option. The mount accepts Trijicon RMR, SRO, and most other optics using the RMR footprint including Holosun, Riton, and similar models (though your optic is not included).
Retention and durability you can rely on
The shell retention system uses an innovative rubber friction mechanism that grips each shotshell securely without plastic retainers that wear out or break. The carrier holds 6 rounds and mounts on the left side of the receiver. Everything is machined from aluminum and finished with hard anodizing that resists corrosion and abuse. Mesa Tactical makes these in the USA and backs every unit with a lifetime warranty.
Installation and compatibility
This carrier mounts directly to the top of your 1301 Tactical using the existing receiver holes with no gunsmithing required. The entire assembly stays put—no moving parts or adjustments to worry about between range trips or duty cycles.

Frequently Asked Questions
Do I need to buy a separate RMR optic to use the SureShell AL RMR?
Yes, the mount is included but the Trijicon RMR sight itself is sold separately. The good news is the mount accepts RMR footprint optics from multiple manufacturers like Holosun, Riton, and others, giving you flexibility on which red dot you choose.
Will this mount work with my Holosun or other reflex sight?
It depends. The mount is designed for the Trijicon RMR footprint. Holosun 407C, 507C, and 508T models use this same footprint and will work. Before purchasing, verify your specific optic uses the RMR mounting pattern.
How is this different from a standard side saddle with a rail?
Instead of bolting a Picatinny rail on top and then mounting an optic to that rail, the SureShell AL RMR has a precision-machined mount built directly into the carrier. This keeps the setup cleaner and maintains excellent co-witness with your factory ghost ring sights without extra rail height.
Is any gunsmithing needed to install the SureShell AL RMR?
No. It mounts using the factory drilled and tapped holes on top of the Beretta 1301 receiver. You'll need basic tools to attach the mounting hardware, and Mesa Tactical includes all necessary screws and components.
