Ultradyne Adjustable Stock Gen 2 Features The Ultradyne USA Adjustable Stock Gen 2 is machined from 6061 T6 aluminum a lightweight and durable alloy that keeps the stock rigid under recoil while minimizing overall weight on the rifle. Its Cerakote finish in black resists wear corrosion and the scuffs that come with regular range use keeping the stock looking and functioning like new well after installation. The dual mounting interface accepts either a 1913 Picatinny rail or a mil-spec threaded buffer tube giving shooters flexibility to mount it on a wide range of chassis systems and receiver configurations. This versatility makes the stock a practical upgrade for anyone transitioning between different rifle builds without needing a different stock for each one. Length of pull adjusts across a 12.75 inch to 13.75 inches range stretching to 14.75 inches when paired with the optional spacer kit so shooters can fine tune the fit to their stance gear loadout and body type. That adjustability matters most in precision and competition settings where a consistent cheek weld and shoulder pocket directly affect repeatable accuracy shot after shot. Designed to pair exceptionally well with the Ultradyne UD Chassis and Picatinny Chassis this stock rounds out a cohesive purpose built rifle system rather than functioning as an afterthought accessory. The Ultradyne USA Adjustable Stock Gen 2 is a modular precision oriented buttstock for sale at GrabAGun for shooters building a dialed in competition or precision rifle setup.
