  • Adjustable Buttstock | TechLink
    A quick twist back locks the buttstock in position The ability to quickly adjust pull length is important to accommodating various sizes of firearm users different shooting styles and usage situations or even adjusting to seasonable or mission specific outerwear such as jackets and body armor The adjustable feature of some competing technologies can be accidentally activated while other designs are not easy to use The ARDEC device overcomes both shortcomings in a unit that is highly durable It is currently deployed for use on M240 and M249 machine guns ARDEC s adjustable buttstock also features a removable modular check rest that provides convenient storage for important small items and supplies The buttstock can be utilized with or without a buffer device and can be modified to accommodate a variety of firearms Benefits Simple One button press and a quarter turn rotation of the stock are the only movements required to adjust the pull length of the buttstock Reliable The single button and twist combination ensure the device length changes only when desired by the user Military Grade The durable ARDEC design is standard issue for new US Army M240 and M249 variants and is being retrofit on existing weapons

  • Twisted Rudder | TechLink
    is a reduction in cavitation that provides several benefits including less rudder erosion decreased drag increased turn capabilities and reduced noise The rudder has been thoroughly tested and is currently in service on US Naval destroyers Benefits Higher speeds before experiencing cavitation Cavitation experienced by naval vessels at 23 knots with the previous rudder design was delayed until 30 knots with the twisted rudder design Lower maintenance requirements Less cavitation greatly reduces the amount of rudder erosion Efficient Drag is reduced resulting in greater fuel efficiency and improved turning performance Proven technology The twisted rudder technology is in service on active duty US Navy destroyers The Opportunity The action of a propeller causes the angle of water flow to vary along the span and chord of a rudder When water flows at a high speed and at a slight angle over a rudder surface the result is cavitation that reduces performance increases erosion of the rudder s coatings and produces undesirable noise The US Navy has created a rudder that can twist from top to bottom in order to more favorably match the actual flow of water from a propeller and thus reduce or greatly delay the onset of cavitation
