Ruger 90773 Precision Rifle Buttstock Assembly Black Steel/Aluminum/Nylon
The Ruger 90773 Precision Rifle Buttstock Assembly is a fully adjustable stock built to dial in fit and comfort on your precision rifle platform. Whether you're setting up a new Ruger Precision Rifle or retrofitting an existing rifle with a standard MIL-SPEC buffer tube, this stock delivers the kind of customization serious long-range shooters and competition riflemen expect. Extensive adjustment in length-of-pull, cheek rest height, and recoil pad position means you can tune the gun to your body and your shooting position—not the other way around.
Built from steel, aluminum, and nylon with hard-coat anodized and nitride finishes, the 90773 is engineered to handle field and range abuse without compromise. The design eliminates sharp edges and corners, so you get comfort during long sessions behind the gun. A QD sling pocket gives you a reliable attachment point for quick-detach sling systems, and an M-LOK slot on the flat bottom accepts a bag slider for rock-solid rifle positioning on a rest or sandbag.
This buttstock is fully reverse compatible with previous generations of Ruger Precision Rifles and works with any rifle using a standard MIL-SPEC buffer tube, making it a logical upgrade for shooters looking to maximize accuracy and repeatable form. At just 1.8 lbs, it won't bog down your rifle's balance.
