ATI Halo Side Saddle for Mossberg Shotguns

Advanced Technology International (ATI) is now taking pre-orders on a new side saddle for the Mossberg 500/590 series of shotguns.  This new side saddle system allows the shooter to carry up to nine more shells mounted to the receiver.  Other side saddle products allow the shooter to carry five or six shells on the side of the receiver opposite the ejection port.

The ATI Halo side saddle is an accessory device that is roughly the shape of an inverted “U”.  It mounts to the top of the receiver and is held in place by two screws that replace existing set screws. Users can then mount Add-A-Shell holders on each side of the “U”: three on the side of the ejection port, six on the opposite side.

The top of the Halo system is a Picatinny rail.  So, in addition to the extra ammo, the shooter can easily add an optic such as a holo sight.

The entire system carries a retail price of $139.99.
