The Christensen Arms Ranger 4.5 .22 WMR bolt-action rifle brings precision rimfire shooting to hunters and shooters who demand accuracy without the recoil or ammunition costs of centerfire rounds. Built on a Christensen Arms aluminum receiver with a hand-lapped carbon fiber tension barrel, the Ranger 4.5 delivers match-grade performance in a compact 18-inch platform that weighs just 5.1 pounds—light enough for all-day hunting or range sessions without fatigue. Whether you're zeroing in on small game, training for accuracy fundamentals, or simply enjoying a day at the range, this rifle combines modern engineering with the kind of precision that Christensen Arms is known for.

The receiver runs dual opposing locking lugs and dual ejectors for reliable operation, while the carbon fiber composite stock features a palm swell and ambidextrous grip to accommodate left- and right-handed shooters equally. A threaded muzzle accepts suppressors or brakes, and the integrated 0 MOA Picatinny rail gives you a clean platform for mounting optics without needing additional rail systems. The Trigger Tech Rem 700 style trigger breaks cleanly and predictably, and the rifle ships with sling studs and a recoil pad as standard equipment.

Christensen Arms backs the Ranger 4.5 with their Sub-MOA at 50 Yards Guarantee, so you know the rifle is built to deliver. Magazine compatibility with Ruger 10/22 patterns means affordable, proven ammunition handling. The .22 WMR cartridge delivers more velocity and energy than standard .22 Long Rifle, making it suitable for medium-range small game and varmint work while remaining hearing-safe and shooter-friendly.
