About the Ultradyne Gen 2 Adjustable
The UD Gen 2 adjustable butt stock attaches to any 1913 Picatinny or mil spec threaded rear mounting interface, so a chassis rail and a standard buffer tube both work. Length of pull adjusts from 12.75 to 13.75 inches, and a spacer kit takes it out to 14.75 inches.
The stock folds to shorten the rifle for transport and storage, and the body is aluminum. Ultradyne pairs it with the UD Chassis and the Picatinny Chassis, though it will attach to any host with one of those two rear interfaces, which covers a lot of rifles.
