Chassis combo's bundle an Ultradyne Chassis with a Gen 2 Adjustable Butt Stock and grip for a ready-to-build platform with just one easy purchase. There are options for both a basic, lightweight build, as well as a primo, folding build; and buying the combo saves you compared to purchasing each item separately.

Designed for shooters, the combo delivers the core ergonomics and modularity of the UD platform: adjustable length-of-pull and cheek rise on the stock for personal fit, and different forend length options for different build purposes. Choose either our original UD Chassis to get the most value at a low price, or choose the new Picatinny Chassis to get the most included features. CNC-machined in house from quality materials, our chassis combos provide a fine-tuned final product that will help lead to success in the field.
