The Christensen Arms Magnum Bolt Face Short Action (model 810-00144-00) is a precision-crafted foundation for a custom magnum-class rifle build, engineered to deliver strength, accuracy, and long-range capability right from the start. Machined from bead-blasted stainless steel, this short action features a magnum-sized bolt face that accommodates larger case head diameters, making it ideal for cartridges with heavy recoil and big payloads. It comes equipped with TriggerTech-ready trigger pins so you can install your choice of premium trigger, and its dual recoil lugs provide a solid bedding point for consistent lockup and shot-to-shot repeatability. An integrated 20 MOA Picatinny rail on the receiver adds built-in elevation for optics, giving shooters extra adjustment range for long-distance engagement without the need for riser bases. Designed for builders and enthusiasts who want a durable, precision-ready action as the heart of a custom rifle, this Christie Arms magnum short action balances rugged construction with thoughtful features that support performance in harsh field conditions or competitive long-range use.
