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.
