ActionFlex full-contact products incorporate a unique patented piston system that gives the user complete realism.

ActionFlex Piston System 
The patented ActionFlex Piston System assembly is constructed of high-tensile bushings, allowing the weapon the flex and while maintaining the original structure. When the multi-part system flexes, it transfers the force of the user's hit through the weapon to the target, replicating the flex of a multi-layered steel blade. This type of flex action gives the weapon the performance, durability and longevity expected of the ActionFlex training products and is perfect for training.
