Meta Tactical Llc Mesa Surshl Al/Rmr Mnt Ben M4 6 12Ga
The Meta Tactical Mesa SureShell aluminum carrier for the Benelli M4 shotgun brings modern optics mounting to a proven combat platform. This six-shell carrier pairs a practical onboard ammunition solution with an integrated mount specifically machined for a Trijicon RMR reflex sight—letting you run fast, close-quarters optics without permanent gun modification. If you're building a tactical 12-gauge for home defense, patrol, or dynamic shotgun sports, the Mesa RMR mount eliminates the need for aftermarket Picatinny rails and gives you a clean co-witness setup with your M4's factory ghost ring sights.
Built from 6061-T6 aluminum and hardened with Type 3 anodizing, this carrier handles the recoil and wear of 12-gauge shooting while keeping weight down. The mount itself is precision machined—no stamped or cast parts here—and secures to your receiver via the factory drilled and tapped holes. Installation is straightforward, and you get the advantage of carrying six shells right on the gun, positioned for fast reloads.
Note that the RMR sight itself is not included; you'll source that separately based on your preference for dot size and reticle. The Mesa's engineering assumes you're committed to the RMR platform and want a mount that does one thing exceptionally well.

Frequently Asked Questions
Will this work on other shotgun platforms besides the Benelli M4?
No. This Mesa carrier is designed specifically for the Benelli M4. It attaches via the M4's receiver holes and will not fit Benelli M2, Beretta 1301, or other shotgun models without extensive modification.
Does the RMR sight come with this carrier?
No. The RMR reflex sight is sold separately. This product provides only the integrated mount for a Trijicon RMR.
How does it co-witness with the factory ghost rings?
The Mesa mount is machined so that when your RMR is installed, the reflex dot sits at the same sight picture height as your M4's standard factory ghost ring sights. This gives you flexibility to use either aiming system or both together.
Is installation permanent or reversible?
The carrier mounts via drilled and tapped holes in your Benelli M4's receiver. Removal is straightforward, but drilling into the receiver is a permanent modification to your shotgun.
