Ruger Precision 17 HMR 18'' 9-Rd Bolt Action Rifle

Description

The Ruger Precision® Rimfire Model 8403 is a precision-oriented bolt-action rifle chambered in .17 HMR, combining the ergonomics and adjustability of a centerfire precision rifle with a 9-round capacity and the flat-shooting performance of the .17 HMR cartridge. Featuring an 18-inch cold hammer-forged target barrel, Quick-Fit adjustable stock, 15-inch free-float M-LOK handguard, Ruger Marksman Adjustable™ trigger, and factory Picatinny optics rail, Model 8403 is configured for precision rimfire shooting, competition, training, and recreational target use.

The rifle is constructed around a molded one-piece glass-filled nylon chassis and adjustable buttstock assembly, providing a rigid foundation for consistent accuracy. Ruger's Quick-Fit Precision Rimfire stock allows both length of pull and comb height to be quickly adjusted for different shooters, optics, clothing, and shooting positions. Length of pull is adjustable from 12 to 15.50 inches, with molded index marks making it easy to return to a preferred setting.

The adjustable stock incorporates several precision-oriented features, including a flat Picatinny bag rider, a molded tether point for a rear squeeze bag, and a metal QD pocket for sling attachment. These features make the rifle particularly well suited to supported shooting positions.

At the heart of Model 8403 is an 18-inch cold hammer-forged target barrel manufactured from 1137 alloy steel. The barrel features a 1:9" right-hand twist with six grooves and is threaded 1/2"-28 at the muzzle. Ruger includes a factory thread protector that covers both the threads and barrel crown.

Surrounding the barrel is a 15-inch aluminum free-float handguard finished in black hard-coat anodizing. Magpul® M-LOK® slots are positioned on all four sides, providing extensive mounting capability while offering plenty of clearance for larger precision-oriented optics.

Trigger duties are handled by Ruger's Marksman Adjustable™ trigger, which is externally adjustable from 2.25 to 5 pounds. Ruger conveniently stores the adjustment wrench inside a compartment in the buttstock.

One of the Precision Rimfire platform's most distinctive features is Ruger's Big-Gun bolt throw adjustment. Shooters can configure the action for either a traditional 1.5-inch rimfire bolt throw or a 3-inch short-action centerfire-style bolt throw. This provides a training experience that more closely resembles operating a centerfire precision rifle and can help reduce the chance of short-stroking the bolt during competition.

An oversized bolt handle, modeled after the full-size Ruger Precision Rifle®, provides positive bolt manipulation. The rifle also uses an AR-pattern pistol grip and 45-degree reversible safety selector, and Ruger states that it can be configured with most compatible AR-style grips and selectors.

Model 8403 is designed for optics and therefore does not include traditional iron sights. Instead, Ruger installs an anodized 0 MOA Picatinny scope base, providing a factory mounting platform for compatible scopes and other optics.

The important difference between this rifle and Model 8402 is magazine capacity. While both are chambered in .17 HMR, Model 8403 has a 9-round capacity and includes one 9-round JMX-1 rotary magazine. It also accepts Ruger magnum rimfire magazines, including the JMX-1 and BX-15® Magnum.
