Mesa Srshl Ply W/Rfx 1301 Tac 6-12Ga
The Mesa Tactical SureShell shotshell carrier with integrated Trijicon RMR reflex sight mount is a purpose-built accessory for your Beretta 1301 tactical shotgun. This six-shell carrier combines practical ammo storage with a precision-machined optics platform, letting you mount a red dot sight directly to your receiver for faster target acquisition without occupying rail space. It's designed for shooters who run dedicated reflex sights on their 12-gauge and want the optic co-witnessed with factory ghost ring irons.
Built from injection-molded, glass-filled nylon, the SureShell body is lightweight and durable enough for hard use. The aluminum components wear a Type 3 hard coat anodized finish for a flat black look that resists corrosion. Unlike rail-mounted carriers, this design integrates the RMR mount directly into the shell holder, keeping your shotgun's profile compact and keeping your optic exactly where you need it. Installation is straightforward—the carrier mounts via existing drilled and tapped holes on your Beretta 1301 receiver.
If you're running a reflex sight on your tactical 1301, this carrier bridges the gap between shell storage and optics mounting. The co-witness design means your factory sights stay in the fight as backups. Just remember: the RMR sight itself is not included—you'll need to source that separately to complete your setup.

Frequently Asked Questions
Will this shell carrier work with my Benelli M2 or M4?
No. This carrier is designed specifically for the Beretta 1301. Mesa Tactical makes compatible SureShell carriers for Benelli platforms, but they are separate products.
Do I need to have my shotgun gunsmithed to install this?
No. The carrier mounts directly to the drilled and tapped holes already on the Beretta 1301 receiver. Standard tools should be all you need.
Does it come with a Trijicon RMR sight?
No. The carrier includes the precision-machined RMR mount only. You'll need to purchase the red dot sight separately.
How does the co-witness feature work?
When you mount an RMR sight to this carrier, it aligns with your Beretta 1301's factory ghost ring rear sight. This lets you keep your iron sights as a backup while using the reflex sight as your primary aiming reference.
