Magnum Research Magnum Lite SwitchBolt .22LR AR-15 Rifle - SSAT22UT

The Magnum Research Magnum Lite SwitchBolt .22LR AR-15 rifle delivers lightweight, accurate rimfire performance in a semi-auto platform designed from the ground up for shooters who want reliability without the bulk. Built on a receiver machined from 6061-T6 aluminum forgings and finished in hard-coat anodized matte black, this rifle combines the proven accuracy of Magnum Research's MLR rimfire heritage with modern ergonomics and ease of maintenance. Whether you're running .22LR plinking sessions, training new shooters, or working small game, the SwitchBolt's thoughtful engineering—including its gas-assisted blowback operation and 22 Bentz chamber configuration—keeps you on target without drama.

At 4.5 pounds unloaded (4.65 with magazine), the SwitchBolt won't wear you down during extended range days or field work. The 18-inch Ultra aluminum barrel is tensioned for consistency and threaded at the muzzle, giving you the flexibility to add a suppressor or compensator. An integral Picatinny scope base is built into the receiver, so you can mount glass without hunting for rail space or dealing with add-on clamps. The ambidextrous thumbhole stock provides a solid, repeatable hold for both right and left-handed shooters, and sling swivel studs are standard for field carry.

This is a rifle that respects .22LR for what it is: a genuinely effective, low-recoil cartridge for precision work, not a compromise platform. The SwitchBolt's USA-built receiver, integrated mounting solution, and proven gas system mean you spend less time troubleshooting and more time shooting accurately.

Frequently Asked Questions

Is this rifle designed for AR-15 compatibility or as a standalone .22LR?

The SwitchBolt is a standalone semi-auto .22LR rifle with its own receiver platform. While it shares ergonomic and design DNA with the AR family, it is not a direct AR-15 upper or lower swap—it's a purpose-built rimfire system that Magnum Research engineered to be accurate and dependable on its own.

Can I add a suppressor to the SwitchBolt?

Yes. The 18-inch barrel features a threaded muzzle, so you can mount a .22LR suppressor. This is a popular setup for quiet, low-recoil training and small-game work.

What scope mount do I need?

The rifle has an integral Picatinny scope rail machined into the receiver, so you can mount standard Picatinny rings and optics directly without needing a separate rail or clamp.

Is the SwitchBolt ambidextrous?

Yes. The thumbhole stock is ambidextrous, accommodating both right and left-handed shooters comfortably.
