Ultradyne UD5 CHSS Chassis System for Remington 700 Long Action with Stock

The Ultradyne UD5 CHSS chassis system transforms a Remington 700 long action into a precision platform with enhanced ergonomics and modularity. This complete system combines a rigid aluminum chassis with an integrated adjustable stock, providing improved stability for long-range shooting and consistent cheek weld across varying optic heights.

Constructed from aerospace-grade aluminum, the chassis features M-LOK slots for accessory mounting and accepts AICS-pattern magazines. The integrated stock offers length-of-pull and cheek riser adjustments to fit different shooter builds and shooting positions. Installation requires basic gunsmithing tools and familiarity with action bedding—professional installation recommended for shooters without prior chassis system experience.
