The Christensen Arms MPR Rimfire (Christensen part no. 8011202402) is chambered in .22 WMR and built around a 20-inch, button-rifled carbon fiber tension barrel with a precision-lapped match chamber and a threaded 1/2×28 muzzle, finished in a Desert Brown Cerakote. A 7075 aluminum billet chassis carries a folding stock with a locking hinge and MagnaLock technology, an FFT carbon fiber handguard with M-LOK slots, and an adjustable FFT carbon fiber cheek riser for a personalized fit. A TriggerTech trigger built to the Remington 700 pattern delivers a crisp, consistent pull, while dual opposing locking lugs on the precision-machined aluminum receiver back a 0-MOA optic rail for a flat, repeatable scope mount. It feeds from a 9-round Ruger BX-1 pattern magazine sized for the .22 WMR case, and six QD sling mounts plus a monopod-ready Picatinny rail round out a rifle built for hunters who want more range than .22 LR offers.
