The Mesa Tactical PR 8-Round shotshell holder addresses one of the M4's biggest limitations by putting extra ammunition right where you need it. Unlike universal designs or bolt-on adaptations, this carrier is engineered specifically for Benelli M4 and M1014 shotguns. It takes advantage of the factory tapped receiver holes and slides on with minimal effort.
Shells stay put thanks to Mesa's friction-based retention system using Santoprene elastomer tubes. You get black rubbers installed for standard shells, with white alternatives included if you run specialty ammo that needs different tension. The design lets you load shells brass-up or brass-down depending on your preference. Your shotgun's finish stays protected too with the adhesive-backed rubber gasket included in the box.
Machined from 6061-T6 aircraft-grade aluminum with hard coat anodizing, this carrier handles serious use without breaking a sweat. The weight is negligible (8.5 ounces total), so you're not dragging down your handling with dead weight. The 5.5-inch Picatinny rail on top opens up options for mounting optics, lights, or other accessories without losing your shell storage.
Installation is straightforward since the M4 already has drilled and tapped holes waiting. Comes with all mounting hardware, gasket material, alternative tension inserts, and clear instructions. Made in the USA with a lifetime warranty backing every unit. The side saddle design keeps ammunition accessible without interfering with your grip or sight picture.
Yes. The PR model is designed specifically for the M4 and M1014, mounting directly to the factory tapped receiver holes. No drilling or permanent modifications needed. It replaces the factory Picatinny rail and uses the same five mounting holes.
Absolutely. The carrier ships with black rubbers installed for most standard 12-gauge shells. If you run specialty ammo like slugs or different shell types, the included white rubbers offer alternative retention tension. Swapping them out takes just a few minutes.
No. The 5.5-inch Picatinny rail accommodates most standard optics, red dots, and accessories. It's designed to work alongside the shell carrier, so you get the best of both worlds without sacrificing functionality.
The Santoprene elastomer tubes grip shells firmly but allow tool-free access. The rubber friction system holds even under heavy magnum loads and recoil. Many users report shells staying put through extended range sessions without shifting.
