Many precision rifle chassis systems utilize a buffer-tube style attachment based on available AR-15 buttstock systems, but according to Rival Arms, few of them translate well to precision bolt-action rifles. The company designed the new, made-in-the-USA ST-3X Precision Rifle Stock to solve those problems.
Located in Dallas, Texas, Rival Arms provides premium aftermarket handgun and rifle components that are reliable and accurate. Rival Arms parts are built in the USA with materials and coatings held to strict tolerances.
The ST-3X buttstock uses the same AR-15-style mounting system but is purpose-built for chassis rifles. The stock features an adjustable cheek riser that passes through the stock, a machined aluminum frame with a downward-facing M-LOK slot for monopod or Picatinny rail section, and machined ambidextrous flush cups for QD detach slings. The stock is machined from billet aluminum, weighs 28 ounces, and wears a Type III hardcoat-anodized finish. Comb height, length of pull, and the recoil pad are adjustable, and the cheek pad is reversible. The ST-3X installs onto any chassis with a 1.188-16 thread and locks in place with an included castle nut.
