Product Info for Ultradyne UD Picatinny Stock

The UD Picatinny Butt Stock is a picatinny-mounted butt stock built for repeatable fit and easy transport. Designed for shooters who demand precision, modularity, and reliable fit, the UD Picatinny Butt Stock is a purpose-built stock that attaches quickly to any 1913 Picatinny rear mounting interface, and pairs exceptionally well with our UD Picatinny Chassis. Machined from a solid billet of 6061-T6 aluminum, the stock offers smooth, repeatable adjustments for cheek height and length-of-pull so you can dial in consistent eye-to-optic alignment and shoulder mount. Choose the fixed model for a stream-line, lightweight option, or the folding model for the ultimate compact carry and storage solution. Cerakote finish, optional bag rider, and made in specialized factories, this stock makes your build more modular, easier to pack, and faster to configure in the field.image
