Features:

• Molded one-piece chassis and adjustable buttstock assembly are manufactured with glass-filled nylon for strength stiffness and stability making a solid foundation for accuracy each and every shot. Adjustable buttstock features a flat Picatinny bag rider making it easy to affix a rear monopod. A molded-in window provides a tether point for your squeeze bag and a metal QD pocket makes it easy to secure a sling
• Quick-Fit adjustable Precision Rimfire stock allows length of pull and comb height to be quickly and easily adjusted to get proper fit over a wide range of shooter sizes outerwear and shooting positions. Indicating marks molded into the chassis help you quickly return to a previous position.
• 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 your bolt in competition.
• Ruger Marksman Adjustable? trigger has a pull weight range of 2.25 to 5.0 pounds; adjusting wrench is stored in a buttstock compartment.
• Ruger’s own AR-Pattern pistol grip and safety selector incorporates an extended reach for maximum control and access to the 45 degree reversible safety selector. May be configured with most AR-style grips and selectors.
• Anodized Picatinny scope base includes 30 MOA elevation for increased long-range capabilities out of the box.
• Oversized bolt handle for positive bolt manipulation (same as the Ruger Precision Rifle®).
• 15″ free-float handguard is made of hard black anodized aluminum and features Magpul® M-LOK® slots on all four sides for improved scope clearance and easy mounting of M-LOK-compatible rails and accessories.
• 18″ target barrel is cold hammer-forged from 1137 alloy steel to create ultra precise rifling for excellent accuracy. Barrels can be replaced easily by a competent gunsmith using AR-style wrenches and headspace gauges.
• Threaded barrel (1/2″-28) for standard muzzle accessories like the Silent-SR® suppressor comes with a factory-installed thread protector covering both the threads and crown.
