UD Chassis Combos (Coming Soon)
$579.00 – $749.00
Description
Coming soon! UD Chassis Combo’s bundles a precision Ultradyne Chassis with a Gen 2 Adjustable Butt Stock and grip for a ready-to-build platform with just one easy purchase.
Get everything you need to start building a rifle that fits you, without hunting for parts. Each combo is tuned for fit, function, and value. There is an option 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, a secure rear mounting interface with either picatinny or buffer threads for repeatable stock attachment, and a one-piece full service chassis that includes every feature a consumer may want in a precision rifle. 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.
