The Ruger American Rimfire® Model 8322 is a versatile .22 WMR bolt-action rifle designed for small-game hunting, varmint control, and precision recreational shooting. Featuring an 18-inch cold hammer-forged threaded barrel, 9-round rotary magazine, Williams™ fiber optic sights, interchangeable stock modules, and the Ruger Marksman Adjustable™ trigger, the 8322 combines excellent accuracy with the increased velocity and energy of the .22 Winchester Magnum Rimfire cartridge.
Built on Ruger's proven American Rimfire platform, Model 8322 utilizes the company's Power Bedding® integral bedding block system, which positively locates the receiver while free-floating the barrel for enhanced accuracy and repeatable shot placement. The Ruger Marksman Adjustable™ trigger allows shooters to customize trigger pull weight for a crisp, consistent break without compromising reliability.
The rifle features an 18-inch cold hammer-forged alloy steel barrel chambered in .22 Winchester Magnum Rimfire (.22 WMR). The barrel utilizes a 1:14" right-hand twist and comes factory threaded 1/2"-28 with a knurled thread protector installed, allowing the attachment of compatible muzzle accessories where legally permitted.
Model 8322 features a durable black synthetic stock with Ruger's modular stock system. Two interchangeable comb modules are included—a low comb for iron sights and a high comb optimized for scope use—allowing the rifle to be easily configured for different shooting setups. The standard stock provides a comfortable 13.75-inch length of pull suitable for most shooters.
The rifle comes equipped with Williams™ fiber optic sights, including a bright green fiber optic front sight and an adjustable rear sight for excellent visibility in varying light conditions. The receiver incorporates a 3/8-inch rimfire scope base and is drilled and tapped for Weaver® #12 bases, providing multiple options for optic installation.
The rifle feeds from Ruger's reliable 9-round rotary magazine designed specifically for .22 WMR cartridges. Additional features include a 70-degree bolt throw, tang-mounted manual safety, oversized bolt handle, sling swivel studs, and a lightweight 5.5-pound overall weight that makes the rifle easy to carry afield.
Combining .22 WMR performance, a threaded barrel, modular stock system, adjustable trigger, and Ruger's proven bolt-action design, the Ruger American Rimfire Model 8322 is an excellent choice for hunters and shooters seeking a lightweight, accurate rimfire rifle.
