Magnum Research MR SwitchBolt 22 LR | 18-inch | 10+1

The Magnum Research MR SwitchBolt is a semi-automatic rimfire rifle built around an 18-inch tensioned aluminum barrel with a threaded muzzle and a Hogue OverMolded black stock. The receiver is machined from aircraft-grade aluminum and includes an integrated Picatinny rail and a charging handle that can be configured left or right. This configuration is well suited to precision rimfire practice and small-game field work; pair it with a quality optic such as a Vortex Crossfire II 2-7×32 for reliable, sub-$1000 performance that complements the rifle’s balance and sight radius.
