Planning your next backcountry adventure? The Meligun MG-22 crams a six-shot .22LR revolver into a tactical knife handle, creating the kind of hybrid tool that makes survivalists giddy and ATF agents reach for their rulebooks. This precision-engineered curiosity bridges two distinct worlds—tactical knives and firearms—through audacious American craftsmanship that demands both admiration and skepticism.
This isn’t your grandfather’s Boy Scout knife. The MG-22 represents a triumph of miniaturized firearm engineering wrapped in tactical blade functionality.
The MG-22 packs a 6.7-inch sharp blade alongside a 3.5-inch rifled barrel with 1:16 twist, delivering genuine firearm performance from what appears to be standard EDC gear. Six rounds of .22LR ammunition hide in the handle’s revolver cylinder, accessible through a thumb-operated trigger that deploys with two quick tab twists. The engineering tolerances are tight enough to minimize gas escape while maintaining reliable function across various .22LR loads—a remarkable achievement given the space constraints.
Live-fire tests confirm this thing actually works. Real-world performance validates the engineering promises made by Meligun, LLC.
The revolver mechanism functions as smoothly as the blade cuts, with users reporting consistent ignition and surprising accuracy despite the unconventional platform. When not deployed for shooting, the MG-22 operates as a “regular knife without distractions”—no visible giveaways betray the hidden firearm. Meligun’s American craftsmanship shows in the hefty construction and user-serviceable design that allows complete disassembly for maintenance. The company’s testing demonstrates reliable function at velocities up to 1,700 FPS across different .22LR loads.
Here’s where reality crashes the party. Federal regulations and ballistic limitations temper the tactical fantasy.
The MG-22 requires NFA Class 3 registration as an “Any Other Weapon,” meaning federal paperwork, background checks, and months of waiting before you can legally own one. Meanwhile, .22LR isn’t exactly a manstopper—you’re betting on shot placement and multiple rounds rather than immediate incapacitation. At $1,499.95, you’re paying premium prices for what’s essentially an extremely well-made conversation piece that happens to shoot. The regulatory complexity alone makes this more collector’s item than practical EDC tool.
If you’re a collector fascinated by innovative American gunsmithing or a survivalist who values multifunctional tools above all else, the MG-22 delivers genuine engineering prowess that justifies its premium positioning. For this niche audience, the MG-22 represents the ultimate expression of “because we can” engineering philosophy. Everyone else might wonder why anyone needs a knife that shoots—until they handle one and understand the appeal of owning something this audaciously clever.
