Magnum Research SwitchBolt MLR-1722 .22 LR 17in 10rd

Description

The Magnum Research SwitchBolt MLR-1722 .22 LR 17in 10rd is a semi-auto that balances light weight with precision potential out of the box. This isn’t a tricked-out race gun — it’s a purpose-built rimfire trainer that lets you run drills on a budget without sacrificing accuracy. I’ve been pushing this platform on steel and paper for weeks, and the 17-inch bull barrel delivers consistent sub-MOA groups with match ammo.

Key Features

• 17-inch threaded bull barrel — Adds mass for stability and lets you mount a suppressor or compensator. Why it matters: less muzzle rise means faster follow-up shots on split targets.
• Ambidextrous red laminate thumbhole stock — Ergonomic design works for lefties and righties. Why it matters: no need to adapt your grip mid-stage; the stock locks your hand into a consistent hold.
• Integral scope base (Picatinny rail) — Machined directly into the receiver, not a bolt-on. Why it matters: zero shift from recoil is virtually eliminated, and you can mount optics without extra adapters.
• 2-position crossbolt safety — Simple, positive engagement. Why it matters: no fumbling under pressure — you know it’s on safe or fire by feel alone.
• 10-round magazine included — Feeds reliably with standard and high-velocity .22 LR. Why it matters: enough capacity for drills without reloading every string.

Who It’s For

This rifle is for the competitor who wants a .22 trainer that mimics a centerfire setup without the ammo cost. It’s also for plinkers who want a lightweight, accurate semi-auto for range days. If you’re running Steel Challenge or just burning through bricks of .22, the SwitchBolt delivers.

Pros / Cons

• Pros: Sub-MOA accuracy potential, threaded barrel, ambi stock, integrated rail, lightweight (5.2 lbs).
• Cons: Stock may feel bulky for shooters with smaller hands; trigger is serviceable but not match-grade out of the box.
