WFD

The Weapons Flotation Device (WFD) is a patented, standardized, lightweight, durable accessory that provides enough inherent buoyancy to float a fully loaded weapons system. The WFD is made of a durable, closed-cell, fire resistant/retardant foam, it can be designed around any weapons platform easily sliding onto standard picatinny rails and stock post.

 
Each WFD kit includes one or two front floats (depending on the weapon size, weight, and desired buoyancy), and an adjustable buoyant stock. An optional over-the-laser adapter is also available. All configurations allow for freedom of movement and provide secure and reliable flotation. 

Each front float easily slides on and off a standard picatinny rail via the innovative, snap fit slider mechanism. On two-piece models, the front floats have tapered, interlocking pieces for a snug fit, and increased stability while in use. 
Stocks fit on standard posts. They are adjustable, can be used on their own, and provide increased shoulder contact, enhancing stability. 

The entire WFD kit is customizable to both weapon type and customer specifications (e.g., size, positive, neutral, or negative buoyancy).  

LBT offers a limited lifetime warranty against manufacturing and material defects for the service life of the product, when used as intended. This does not cover normal wear and tear, modifications, or improper use/care.

Returns are not accepted after 90 days from purchase. Due to the critical nature of body armor, all body armor sales are final. Custom items are also non-returnable, as they cannot be resold.
