Mesa Tactical SureShell Polymer Shotshell Carriers with Rail combine a shell carrier with a MIL-STD-1913 (NATO STANAG 4694) Picatinny rail that accepts optical, sights, lasers or accessories. These shotshell carrier/rail systems mounts by using the drille
These SureShell polymer shotshell carriers for the Mossberg 500 and 590 feature mounting brackets with integral top Picatinny sight rails. Using the top mounting screw holes found on Mossberg 500 and 590 shotguns made since 1997. The SureShell polymer carriers are thus slung on the left side of the receiver, securely fastened at the top. No other shell carrier mounting method is as secure or looks as good.
Mesa Tactical is now offering the SureShell® Shotshell Carrier made from durable, impact resistant polymer. This new polymer shotshell carrier system, available in a six shell configuration, features shell holders injection molded from glass filled polymer, secured to the receiver by a lightweight aluminum back plate with brass threaded inserts. The new SureShell Polymer Shotshell Carrier also includes an innovative dual rubber friction system that reliably holds shotshells in place. Models are available with and without integral Picatinny rails for mounting optics.
The Picatinny rails are machined from aircraft grade 6061-T6 aluminum, which are mil-spec hard anodized and provide an extremely durable non-glare matte finish. The basic saddle rail design provides a robust mounting platform suitable for mounting a variety of optical sights, while a second version, which is nearly identical to the basic version, also includes a Mesa Tactical six-shell SureShell polymer carrier mounted on the left side of the receiver. Both versions are manufactured in compliance with MIL-STD-1913 Picatinny specifications, and no gunsmithing is required for installation.
The principle difference between one model of SureShell and another, is the backing plate, which is designed to mount the carrier assembly on a particular model of shotgun. Side-mount SureShell shotshell carriers for Mossberg , Remington and Benelli M1 shotguns use the trigger group pin holes to secure the assemblies to the weapon; the Benelli M2 Tactical, Benelli M4/M1014, Benelli SuperNova Tactical and some Mossberg 500/590 versions take advantage of the factory-tapped rail mounting holes in the tops of these shotguns and include integrated Pictanny optics mounting rails; another version with an integrated rail is the saddle-mount design for Remington; SureShell Carriers for M4 SOPMOD stocks feature special hardware for attachment to these buttstocks; Adapter Mount SureShell shotshell carriers are designed to be attached to Mesa Tactical Telescoping Stock Adapter accessory mount points.
The following is a breakdown of the various components that make up the SureShell Polymer Carrier system.
SureShell Saddle Rails feature a MIL-STD-1913 (NATO STANAG 4694) Picatinny sight rail along the top, and a six-shot SureShell polymer shotshell carrier yoke on the left side of the receiver. The rail is notched at the rear to accommodate Scattergun/Wilson style ghost ring sights. SureShell shotshell carriers are assemblies comprising an injection molded-glass filled nylon yoke and backing plate and a dual Santoprene® elastomer tube. The yoke features six vertical bores .700” or .810” in diameter to accept 12-gauge shotgun shells. The shells are securely retained by the dual elastomer tube interfering with the bores. In many cases, shells can be confidently retained in a brass down as well as a brass up configuration, though brass up is most secure.
The elastomer used to interfere with the shell bores and thus retain the shells in the SureShell shotshell carrier is made of tough Santoprene thermoplastic. We are required to publish the following message to comply with California’s Proposition 65:
WARNING: This product contains a chemical known to the State of California to cause birth defects or other reproductive harm.
SureShell carriers are assembled at the factory with a black Santoprene elastomer tibe with a shore value, or stiffness, of A64. This has proven to be optimal for most customers and in most situations. However, some customers require a stiffer elastomer and for those operators we have included an alternative white elastomer tube with a shore value of A73. The black elastomer tube can be swapped for the white one if tighter shell retention is required.
Several platforms use custom fasteners called Chicago screws. These are paired male and female fasteners that, when screwed together, meet at their respective shoulders for a precise fit on whatever platform they are made for (each shotgun platform will use different length Chicago screws). Ideally, when they are tightened against each other, they also secure the shell carrier without pinching the receiver. Two hex keys are provided for each screw size. Sometimes it is necessary to screw the fasteners in from both sides simultaneously.
*It is important to realize that once the Chicago screws are tightened against each other, they aren’t going to get any tighter, and applying too much torque will snap them at the center. It is useful to practice tightening them outside the shotgun before installation, to get a hang for how tight they can get, and also to clean the threads of any dirt or debris.
The Adapter Mount SureShell shotshell carrier is designed to be used with shotguns already equipped with the Mesa Tactical High-tube or Lowtube Telescoping Stock Adapter. If you do not already have a Mesa Tactical Telescoping Stock Adapter system installed on your shotgun, this carrier cannot be used. The other Mesa Tactical SureShell carriers described in this guide can be fitted to shotgun receivers without the stock adapter installed.
Machined from 6061-T6 hard anodized aircraft aluminum, the shell holders incorporate an entirely new internal elastomer shell retention system that eliminates the need for the flexible plastic shell retainers used on conventional shell holders. A unique arrangement of threaded fasteners secures the shell holder to the shotgun receiver without the risk of stripping threads in the aluminum bracket. The Shell Holders will be available in four-shell, six-shell and eight-shell versions. Four shell versions will be available for mounting on the right side of the shotgun receiver, while all versions will fit on the left side. SureShell shotshell carriers are available in three configurations: four-shell, six-shell and eight-shell. The six-shell and eight-shell configurations can be installed on the left side of the receiver, while the four-shell carriers can be installed on either side of the receiver. Carriers can also be installed pointed back toward the stock.
These shell carriers mount to the sides of standard M4 SOPMOD buttstocks, to the Urbino Tactical stock cheek riser, or Benelli pistol grip fixed stock (does not fit Benelli M4 stock or Urbino Tactical stock).
Factory shotgun forends, except “tactical” forends, often feature significantreceiver overlap when the bolt is pulled back. These forends will need to be cut down or replaced with aftermarket “tactical” forends to be used with some SureShell shotshell carriers. Before you install a SureShell shotshell carrier, measure your forend’s receiver overlap and compare it to the furthest forward point of the shotshell carrier. Then cut any potential overlap or interference off the end of theforend with a miter saw or a rotary arm saw for a perfect fit.
The SureShell Polymer Shotshell Carrier is available for the following 12 gauge shotgun platforms:
These SureShell polymer shotshell carriers for the Mossberg 500 and 590 feature mounting brackets with integral top Picatinny sight rails. The brackets are secured to the weapon using the top mounting screw holes found on Mossberg 500 and 590 shotguns made since 1997. The SureShell aluminum shotshell carriers are thus slung on the left side of the receiver, securely fastened at the top.
The 20 inch rails are anchored at the front by a magazine clamp that features either a short length of Picatinny accessory rail at the bottom, or a sling swivel stud. The front clamp interferes with the barrel lug on 18 inch Mossberg 590s, and so are incompatible with these platforms. Twenty inch Mossberg 590s fit just fine, however.
No other shell carrier mounting method is as secure or looks as good. No gunsmithing is required to install the SureShell Saddle Rail, except for optional forend alterations as described above. Picatinny Rails are also available without the shell carriers. Click Here
