The extraordinary SwitchBolt .22LR rifles are an evolutionary extension of the famously lightweight and accurate MLR rimfire rifles from Magnum Research. Built in the USA the SwitchBolt receivers with integral Picatinny rail are machined from a 6061-T6 forging then hard coat anodized for an extremely durable finish. SwitchBolt rifles come equipped with a bolt handle on the left side of a right handed bolt. The result is an extremely fast and handy configuration for a right-handed shooter whose trigger hand never has to leave the stock to charge the rifle.
