Brand new This kit essentially provides a conversion to 590S functionality, but in a more robust design. It contains patent-pending Universal Cartridge Adapter and low-drag no-snag Magazine Follower which allows smooth cycling of 1-3/4" Minishells up to 3" Magnum cartridges in the same magazine. This kit is compatible with any Mossberg 12-Gauge pump-action firearm with a 3" Chamber and machined grooves in the receiver.
