Christensen Arms MPR Rimfire .22 LR | 16 in | 801-12020-00

The Christensen Arms MPR Rimfire is a bolt-action .22 LR chassis rifle built around a carbon fiber tension rimfire barrel and a lightweight 7075 aluminum chassis. It features a folding stock with adjustable length of pull and an adjustable FFT carbon fiber cheek piece for a compact, packable system. The muzzle is threaded 1/2×28 to accept common rimfire accessories and the rifle ships with a Ruger BX-1 magazine.

For optics, a versatile rimfire-capable scope such as the Vortex Crossfire II 2-7×32 pairs well with this platform while staying well under $1,000 and providing an appropriate magnification range for rimfire target work and small-game hunting. Typical applications for the MPR Rimfire include precision rimfire competition and small-game hunting or dedicated range training.
