The Venom 10 Rnd. Box Kit delivers faster cycle times, greater shell capacity and lightning fast reloads to your Mossberg 12 gauge, transforming your shotgun into a Sidewinder Venom mag-fed tactical shotgun system.

Specifically developed for use with pump action shotguns, the Wraptor forend integrates three picatinny rails for mounting multiple accessories, an integrated/patented heat shield with threaded inserts for mounting an optional kelly grip, and a patented 'sight tunnel' which allows the operator to rapidly locate the sights and acquire targets.
