The Christensen Arms MPR Rimfire (Christensen part no. 8011202700) is a bolt-action .22 WMR rifle built around a 16-inch carbon fiber tension barrel and an aluminum chassis finished in Tungsten Cerakote with a bi-tone metal treatment. Stepping up from .22 LR, .22 WMR adds meaningful range and knockdown power for small game and predator hunting while keeping the same lightweight, packable chassis. The folding stock adjusts for length of pull and comb height, and a TriggerTech trigger delivers a crisp, consistent pull. An FFT handguard adds M-LOK slots for lights, bipods, or other accessories, and the rifle feeds from a 9-round Ruger BX-1 pattern magazine sized for the larger .22 WMR case.
