Christensen Arms MPR Rimfire 17HMR 18" Black Nitride Rifle - Model 8011202201

The Christensen Arms MPR Rimfire in 17HMR is a precision rimfire rifle built on a modern chassis platform that merges competition-grade accuracy with genuine packability. Built around a carbon fiber tension barrel and aluminum billet receiver, this 18-inch rifle strips down to fit in a pack without sacrificing the adjustability and modularity that set it apart from traditional rimfire options. If you hunt small game at distance, shoot rimfire competitions, or want a serious plinker that actually holds zero, the MPR Rimfire delivers engineering usually reserved for centerfire precision builds.

The heart of the rifle is Christensen Arms' carbon fiber tension barrel, precision lapped and button rifled with a match chamber. The 17HMR chambering gives you flat trajectory and minimal wind drift—ideal for extended-range varmint work and hunting. Threading (1/2 x 28 standard) lets you add a suppressor to tame the report and recoil, a real advantage in rimfire shooting. The receiver is machined aluminum with dual extractors, dual opposing locking lugs, and a Remington 700–style TriggerTech trigger for clean, predictable breaks.

The chassis is where the MPR Rimfire shines for field use. The 7075 aluminum billet frame accepts a 10.5 or 14-inch FFT carbon fiber handguard with M-LOK slots for mounting lights, lasers, and accessories. The folding stock locks down securely via MagLock technology and lets the rifle collapse for transport or tight shooting positions. You get adjustable length of pull (12.5–14.5 inches), an adjustable FFT carbon fiber cheek riser, six QD flush-cup mounts, and a monopod Picatinny mount ready—giving you the flexibility to dial in your setup exactly how you want it. The AR-compatible grip means most shooters will grab it like a familiar friend.

V-block bedding keeps the barrel floated and consistent shot to shot. Ruger BX-1 magazine compatibility ensures reliable feeding and cheap spares. Whether you're zeroing for competition, glassing a prairie for groundhogs, or just ringing steel on a calm afternoon, the MPR Rimfire handles it all without the weight or bulk of a full-size precision rifle.
