The Ruger 8400 Precision Rimfire 22 LR is a versatile and highly accurate bolt-action rifle designed for precision shooting and tactical training. Featuring a molded one-piece chassis and adjustable buttstock assembly made from glass-filled nylon, this rifle provides a solid foundation for accuracy and stability. The adjustable Quick-Fit Precision Rimfire stock allows for quick and easy adjustments to length of pull and comb height, ensuring a proper fit for a wide range of shooter sizes and positions. The Big-Gun bolt throw adjustment enables shooters to change from a rimfire 1.5-inch bolt throw to a short-action centerfire 3-inch 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, and the adjusting wrench is conveniently stored in a buttstock compartment. The rifle also features an AR-Pattern pistol grip and safety selector, providing extended reach and maximum control. An anodized Picatinny scope base with 30 MOA elevation enhances long-range capabilities, while the oversized bolt handle ensures positive bolt manipulation. The 15-inch free-float handguard, made from hard black anodized aluminum, features Magpul M-LOK slots for improved scope clearance and easy mounting of accessories. The 18-inch target barrel, cold hammer-forged from 1137 alloy steel, creates 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. With a 15-round capacity and accepting all 10/22 magazines, this rifle is ideal for both hunting and recreational shooting. Weighing 6.8 pounds and measuring 35.13 to 38.63 inches in overall length, the Ruger 8400 Precision Rimfire 22 LR strikes a balance between maneuverability and robust construction, making it a top choice for precision enthusiasts.
