Description
The Chiappa Firearms M6 20 Ga/22 WMR Combo is a modern survival rifle, a break-open, over-under firearm that combines a 20-gauge shotgun barrel with a .22 WMR rifle barrel in a single, compact 18.5-inch package. It’s a purpose-built tool for the backwoods, offering serious versatility in a lightweight, packable format. I’ve put a mix of birdshot, slugs, and .22 WMR rounds through this one, and it’s a straightforward, no-fuss performer that fits a specific niche perfectly.
Key Features
- Dual-Caliber Survival Platform: Top barrel is .22 Winchester Magnum Rimfire, bottom is 20-gauge shotgun (3″ chamber).
- Break-Action Simplicity: Robust, single-action design with an external hammer for reliable ignition in all conditions.
- Integrated Storage: The polymer stock houses a waterproof compartment for extra ammo or survival gear.
- Compact & Lightweight: With its 18.5″ barrels, the overall length is just right for a pack or ATV scabbard without being unwieldy.
- Adjustable Sights: Features a rear peep sight and a front blade, both adjustable for windage and elevation.

Here’s the thing—this isn’t a plinker or a clay buster. It’s a tool. The break-open action is simple and strong, with a manual selector to choose which barrel fires first. The trigger is what you’d expect: a long, deliberate pull that’s perfectly serviceable for its role. At just over five and a half pounds, it carries easily all day. The real genius is in the stock; that hollow compartment is perfect for stashing a dozen .22 WMR rounds and a few 20-gauge shells, fire starters, or a small knife. It’s a complete kit in one unit.
Who It’s For
This gun is for the Missouri outdoorsman who needs a reliable, go-anywhere firearm for property patrol, pest control, or as a dedicated survival rifle for camping, hiking, or boating. It’s for the trapper, the farmer, or the prepper who values simplicity and redundancy in their gear. It’s also a fantastic, simple option for introducing a new shooter to both rifle and shotgun fundamentals without the complexity of a semi-auto or pump.
Pros & Cons
Pros: Incredible versatility in a compact package. The dual-caliber capability covers everything from small game to defensive situations. The built-in storage is a brilliant, practical feature. Its simple action means it’s ultra-reliable and easy to maintain—no gunsmithing required for basic cleaning. It’s also just plain fun and utilitarian.
Cons: It’s a single-shot for each barrel, so follow-up shots require a reload. The long, heavy trigger pull won’t win any precision awards. The polymer stock feels durable but isn’t going to win beauty contests. At $517.46, some might balk for a single-shot, but you’re paying for a specialized, niche tool with unique features.
Frequently Asked Questions
Q: Can you fire both barrels at once?
A: No. The Chiappa M6 has a manual selector on the hammer. You must choose to fire either the rifle barrel (top) or the shotgun barrel (bottom) for each shot. This is a safety and practicality feature.
Q: What kind of 20-gauge ammunition can it handle?
A: It chambers 3-inch shells, so you can run everything from light target loads and birdshot to heavier buckshot and rifled slugs. Just ensure any slugs are safe for a smoothbore barrel. The .22 WMR barrel handles all standard .22 Magnum rimfire ammunition.
Q: Is the storage compartment really waterproof?
A: It’s a tight-sealing O-ring design that’s highly water-resistant. For true waterproofing during a river crossing or in heavy rain, I’d still recommend putting critical items like matches or fire starters in a small zip bag inside the compartment as an extra precaution.
Look, if you need a dedicated, packable firearm that can handle a wide array of tasks from dispatching a raccoon in the henhouse to taking small game for the pot, the Chiappa M6 Combo is a compelling choice. Its design has a clear purpose, and it executes that purpose without complication. It’s available at firearms-missouri.com for Missouri residents and nationwide, with an FFL transfer required for firearm purchases. If this fits your specific needs, it’s a hard tool to beat.
