Third Arm Weapon Interface System

<p>The Third Arm Weapon Interface System (TAWIS), or Third Arm, is a passive, stabilizing device developed by the <a href="/facts/United_States_Army/WACWBEK9">US Army</a> <a href="/facts/United_States_Army_Research_Laboratory/CULgwaW6">Research Laboratory (ARL)</a> in 2016 to redistributes the weight of heavy <a href="/facts/Firearm/GuHx4aGE">firearms</a> to make them easier to hold and carry. It weighs  less than 1.8 kg (4 pounds), and consists of a mechanical appendage made out of <a href="/facts/Carbon_fibers/BTIgu1Jx">carbon fiber</a> <a href="/facts/Composite_material/UBysQldh">composite</a> that has one end attached to a carbon fiber plate that fits inside an armor plate pocket and the other end attached to a <a href="/facts/Picatinny_rail/ujtT0Mq7">Picatinny rail</a> on top of the gun. It was designed to permit more accurate use of heavier weapons and reduce fatigue by displacing the weight of the weapon from the arms to the torso, and to mitigate weapon recoil. As of 2018, the Third Arm is a prototype and is still in the testing phase of its development.
