The Christensen Arms MPR Rimfire (Christensen part no. 8011202102) is a bolt-action .22 WMR rifle built around a 20-inch carbon fiber tension barrel, precision-lapped and button-rifled with a match chamber and a threaded 1/2×28 muzzle. The rifle rides on a black 7075 aluminum billet chassis with a folding stock featuring 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 in a Remington 700-compatible pattern delivers a crisp, consistent pull, and 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 equally at home at the range, in the field, or packed down for travel.
