Christensen Arms MPR Rimfire .22 LR | 18″ | 8011202301

The Christensen Arms MPR Rimfire is a chassis-style bolt-action rimfire built around a carbon fiber tension barrel and a lightweight billet aluminum chassis. It folds for packability, uses a Remington 700-style trigger interface, and ships with a Ruger BX-1 detachable magazine. For an optic under $1000 that pairs well with the platform consider a Vortex Viper PST Gen II 1-6×24 for low- to mid-range precision and quick target acquisition.

This rifle is well suited to precision rimfire target work and small-game hunting at typical rimfire ranges, and its features also translate to informal rimfire competition use.
