The Magnum Research Magnum Lite SwitchBolt .22LR AR-15 is a purpose-built tactical rimfire rifle engineered for shooters who demand speed, accuracy, and a lightweight platform. Born from competitive speed-shooting development and built in the USA, this rifle combines the ergonomic familiarity of AR controls with a rimfire powerplant ideal for training, target work, and recreational shooting. The SwitchBolt's defining feature is its left-side bolt handle paired with a right-handed bolt—a configuration that keeps your trigger hand on the stock while charging, dramatically reducing cycle time for rapid fire sequences. It's the kind of thoughtful design detail that separates a purpose-built tool from a generic conversion.

The receiver is machined from 6061-T6 aluminum forgings and hard coat anodized for durability in field conditions. An integral Picatinny rail accommodates optics and accessories without additional mounts. This model ships with a 17-inch patterned graphite barrel for a lightweight, handy setup that tips the scales at just 4.25 pounds—light enough to carry all day, substantial enough to deliver the accuracy rimfire shooters expect. The tactical black stock and single 10-round magazine complete a no-frills, mission-focused package.

Whether you're a serious .22LR competitor, a precision rifle shooter honing fundamentals with rimfire, or someone building a lightweight trainer, the SwitchBolt delivers the kind of efficiency and attention to ergonomics you won't find in entry-level plinkers. This is a rifle built for people who shoot, not just people who own guns.

Frequently Asked Questions

Why would I choose a left-side bolt handle?

The SwitchBolt's left-side bolt handle paired with a right-handed bolt lets you operate the charging handle without moving your trigger hand off the stock or adjusting your cheek weld. For rapid-fire shooting or speed competitions, this shaves seconds off your reload cycle and keeps you sighted in. It's especially valuable if you're training for precision rifle skills or running timed courses.

Is this rifle suitable for competitive shooting?

Yes. The SwitchBolt was designed and tested on the professional speed-shooting circuit. The lightweight, ergonomic design, accurate barrel, and fast bolt operation make it well-suited to .22LR competitions and training-focused disciplines.

What's included and what optics does it accept?

The rifle ships with one 10-round magazine and a tactical black stock. It features an integral Picatinny rail that accepts standard AR-platform optics and accessories—scope rings, red dots, magnified optics, and rail-mounted gear mount directly without additional adapters.

How heavy is this rifle, and is it easy to handle for extended shooting sessions?

At 4.25 pounds, the SwitchBolt is exceptionally lightweight. The graphite barrel and aluminum receiver keep it easy to carry and maneuver, making it comfortable for all-day range sessions or training without shoulder fatigue.
