The U7 was designed by Armat Battlefield Systems in 2063. However, it took a full three years before the United States military could be convinced to accept the design. It was finally adopted in 2066.


The U7 is a simple underbarrel design that mounts to the M16A5P rifle. Although it uses a tube magazine, it is cycled by a straight-pull rotating bolt instead of a slide. The magazine holds three rounds, and another round can be loaded into the chamber. The bolt is ambidextrous, with a handle on each side. The manual cycling makes the U7 capable of reliably firing all types of ammunition, including low-powered less-lethal rounds.


U7A1: a U7 with a shortened mount, barrel, and magazine for attaching the weapon to the M933P carbine. Ammunition capacity is 2+1.

U7A2: a U7 with a redesigned mount and shortened barrel and magazine for attaching the weapon to the M41 submachine gun. Ammunition capacity is 2+1.
