UD Chassis

$399.00 – $479.00

Description
Description

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 1.3 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 butt stock, 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.

    UD Adjustable Butt Stock, M-L (LOP: 12.50”-13.75”)

    $279.00

    Description

    The UD Adjustable Butt Stock is machined from solid 6061 T6 making it light enough for a 6-pound hunting rifle, yet strong enough to accommodate accessories and weights for a 16-pound competition rifle. It is fully adjustable and once adjusted, it stays at the desired settings without any slop or annoying rattle. It comes standard with a detachable Bag Rider and QD sling interface.

    Small frame or large, nearly any shooter will be able to be custom fitted with one of the two length of pull models. The M-L Model LOP, (”Length of Pull”), is 12.50″ to 13.75″ and The L-XL LOP is 13.50″ to 14.75″. The Cheek Rest interface is also adjustable, allowing for up and down movement of 1.0″ and forward and back movement of 1.25″. Once a perfect fit is made, both the Cheek Rest and Length of Pull are securely held in place by a single set screw. The Ultradyne Recoil Pad offers even more adjustability with 15 different positions up, down, and left or right canted. Whether you have a Bolt Gun or MSR, the Ultradyne Adjustable Butt Stock fits any Mil Spec buffer tube interface.
