The Ruger Precision Rimfire 8403 is a versatile and accurate bolt-action rifle designed for precision shooting. Featuring a molded one-piece chassis and adjustable buttstock assembly made from glass-filled nylon, this rifle provides a solid foundation for accuracy with every shot. The adjustable stock allows for quick and easy adjustments in length of pull and comb height, ensuring a comfortable fit for a wide range of shooter sizes and shooting positions. The Big-Gun bolt throw adjustment enables shooters to change from a rimfire 1-1/2" bolt throw to a short-action centerfire 3" bolt throw, reducing the chance of short-stroking the bolt in competition. The Ruger Marksman Adjustable trigger offers a pull weight range of 2.25 to 5.0 pounds, with the adjusting wrench conveniently stored in a buttstock compartment. The AR-Pattern pistol grip and safety selector provide extended reach for maximum control and access to the 45-degree reversible safety selector. An anodized 0 MOA Picatinny scope base makes it easy to mount and zero optics, while the oversized bolt handle ensures positive bolt manipulation. The 15" free-float handguard, made of hard black anodized aluminum, features Magpul M-LOK slots for improved scope clearance and easy mounting of M-LOK-compatible rails and accessories. The 18" target barrel is cold hammer-forged from 1137 alloy steel, creating ultra precise rifling for excellent accuracy. The threaded barrel (1/2"-28) is compatible with standard muzzle accessories like the Silent-SR suppressor, which comes with a factory-installed thread protector covering both the threads and crown. This rifle accepts Ruger magnum rimfire magazines, including the JMX-1 rotary magazine and the BX-15 Magnum magazine. Ideal for both target shooting and hunting, the Ruger Precision Rimfire 8403 is a reliable and versatile choice for any shooter.
