The Mossberg 590S M-LOK 12GA 20″ Ghost Ring expands the versatility of the legendary 590 pump-action platform with the ability to reliably cycle 1¾”, 2¾”, and 3″ 12-gauge shotshells.
At the heart of the 590S is Mossberg’s redesigned feeding system, allowing shooters to mix compatible shell lengths within the magazine without requiring an aftermarket adapter. Using shorter 1¾-inch shells can also significantly increase available magazine capacity.
The 20-inch barrel is paired with highly visible ghost ring sights, providing a fast and intuitive sight picture. An M-LOK compatible forend provides mounting positions for compatible accessories while maintaining the rugged, functional character of the 590 platform.
The 590S retains familiar Mossberg features including the ambidextrous top-mounted safety, dual action bars, twin extractors, and a clean-out magazine tube.
For shooters looking for a highly adaptable pump-action shotgun, the Mossberg 590S M-LOK combines the proven durability of the 590 family with exceptional shotshell flexibility.
