Product Overview
The CHRISTENSEN ARMS MPR RIMFIRE 22LR Bolt Action Rifle is engineered for high-precision rimfire applications, including competitive shooting, advanced marksmanship training, and pest control where repeatable accuracy is paramount. This platform integrates proven design principles from its centerfire counterparts into a purpose-built rimfire system, delivering a robust and consistent shooting experience. Its construction prioritizes minimal weight, structural rigidity, and user-adjustable ergonomics, establishing it as a definitive tool for precision rimfire engagement.
Key Features
Precision Engineering
At the core of the MPR Rimfire’s accuracy is its 16-inch carbon fiber tension barrel. This design minimizes harmonic distortion and heat retention while maintaining a lightweight profile. The precision-machined receiver ensures optimal bore alignment and consistent bolt lock-up. A match-grade, adjustable trigger facilitates a clean and predictable break, critical for precise shot placement. This rifle is backed by the manufacturer’s precision performance guarantee, ensuring its capability to meet stringent accuracy standards.
Chassis System
The Modern Precision Rifle (MPR) chassis is CNC machined from 7075 billet aluminum, providing a rigid foundation for the barreled action. Its design incorporates a folding stock for reduced footprint during transport and storage, without compromising structural integrity when deployed. The stock features extensive adjustability for length of pull and comb height, allowing shooters to optimize their interface with the rifle for consistent sight picture and recoil management, even with rimfire cartridges.
Materials and Finish
The MPR Rimfire features a durable Tungsten Cerakote finish, offering superior resistance to abrasion, corrosion, and chemical exposure, suitable for prolonged field use in varied environmental conditions. The integration of carbon fiber in the barrel further reduces overall weight without sacrificing rigidity or thermal stability. The aluminum chassis components are anodized for enhanced durability and a consistent surface finish.
Reliability and Modularity
Designed for consistent operation, the MPR Rimfire utilizes a smooth-cycling bolt action and is compatible with readily available detachable box magazines. The free-floating handguard is equipped with M-LOK attachment points, facilitating the integration of supplementary accessories such as bipods, weights, or barricade stops. An integrated Picatinny rail on the receiver provides a secure and repeatable mounting platform for optical systems.
