Product Info for Ultradyne UD Adjustable Butt Stock

The UD Adjustable Butt Stock is machined from solid 6061 T6 aluminum, making it light enough for a lightweight hunting rifle, yet strong enough to accommodate accessories and weights for a heavy competition rifle. It is fully adjustable with an ergonomic thumb screw, 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.image

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?. Simply remove the cheekpiece and rotate the butt stock body around the buffer tube to adjust length of pull. The cheek rest interface is also adjustable by removing an internal screw located under the front protruding surface of the cheekpiece. This allows for forward and back movement of 1.25?. You can also adjust the cheekpiece vertically by loosening the provided thumb screw. Once a perfect fit is made, lock the cheek rest height with the thumb screw, or with the provided set screw. The Ultradyne recoil pad offers even more adjustability with 21 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.
