ULTRADYNE UD Chassis – Remington 700 Long Action

The Ultradyne 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. This makes it suitable for both hunting rifles that weigh as little as 6 pounds and long range target rifles that weigh up to 16 pounds. When paired with the Ultradyne Adjustable Butt Stock, it is lighter than most factory stocks yet has the ability to add up to 5 pounds with optional weights.

The Ultradyne 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.
