The .22 LR semi-auto market is full of options, but few combine reliable cycling, an optics-ready platform, and an intentional price point the way serious shooters expect. Whether you’re building a training-sidearm, a backyard plinker, or a compact trail gun, the balance of slide dynamics and modular mounting matters for consistent performance.

BLUE LINE ISSC M22 OMNI .22

The M22 OMNI’s engineered slide is the headline feature: optimized to run on standard .22 LR ammunition so shooters don’t have to rely on high-velocity rounds for consistent cycling. That matters when your range budget or training plan calls for standard-velocity ammo. If you prefer an optic, the newly developed quick assembly system lets you mount or remove a red dot in seconds, and a mounting plate is included with every gun.

Field-use features that matter

Caliber: .22 LR — lightweight, low-recoil, inexpensive to shoot, and ideal for marksmanship fundamentals. The M22 OMNI’s compatibility with standard-velocity .22 LR ammunition reduces stoppage variables during extended drills. Keep in mind that using an optical sight adds mass to the slide/upper assembly; while the slide is optimized, heavier optics may necessitate higher-velocity cartridges to maintain flawless cycling.

Ergonomics and controls

Magazine capacity is a single 10-round magazine, a practical balance for range and recreational use. The sight package combines an adjustable rear with a fixed front for precision iron-sight alignment, while a match grade trigger provides a consistent break for repeatable shots. These elements together make the M22 OMNI a strong training tool and an approachable option for shooters refining sight acquisition and trigger control.

Price sits at $239.99, positioning this platform as an affordable, purpose-built semi-auto for shooters who want optics-ready convenience without a steep investment. View product details and pricing to confirm availability.

Practical recommendations

Run a mix of standard .22 LR brands to verify reliability before committing to a specific feed; if you plan to use a mounted red dot regularly, test a handful of high-velocity loads to determine whether the added optic mass affects cycling. Maintenance is straightforward: keep the slide and feed path clean and inspect the included mounting plate for secure interface with your chosen optic footprint.
