UD Chassis

The UD Chassis is crafted from a solid bar of 6061 T6 Aircraft Aluminum for exceptional strength and durability. The one-piece design weighs between 1.1 and 1.5 pounds, depending on the model. When paired with the Ultradyne Gen 2 Adjustable Butt Stock, it is lighter than most factory stocks yet has the ability to add optional weights if desired.

The UD Chassis is packed with features including an adjustable magazine release lever, compatibility with AICS magazines, ability to work with any Mil-Spec carbine buffer tube, a built-in Arca rail, M-LOK slots on three sides, and Dynalock technology to ensure a secure fit. The action is held in place with V-channel bedding that can accommodate free-floated barrels up to 1.35 inches in diameter.

Please note Chassis compatibilities under the compatibility tab.
