Ultradyne Gen 2 Adjustable Folding Stock Bronze

Ultradyne's Gen 2 adjustable butt stock in bronze. It mounts to any 1913 Picatinny or mil spec threaded rear interface, so a chassis rail and a standard buffer tube both work. Length of pull runs from 12.75 to 13.75 inches, with a spacer kit extending it to 14.75 inches.

It folds for transport and storage, and the body is aluminum. The bronze color is a departure from the standard black hardware most rifles wear, and it matches other bronze parts if that is the build you are after. Ultradyne designed it around the UD Chassis and the Picatinny Chassis.
