Chiappa M6 Combo 12GA & 22WMR 18.5″ Folding
About this product
What is the Chiappa M6 Combo 12GA & 22WMR 18.5″ Folding? It's a break-action, over-under survival rifle with a 12-gauge shotgun barrel on top and a .22 Winchester Magnum Rimfire barrel underneath, specifically engineered for compact transport and backup use. This isn't a sporting clays gun or a 500-yard plinker – it’s a mechanical redundancy tool built for the field where primary gear can fail. The unique combination caliber provides immediate versatility without the need to carry a second, dedicated firearm, which is a serious consideration for survival loadouts and remote work.
What is the Chiappa M6 used for?
The Chiappa M6 is used for compact, rugged, and lightweight backup utility for hunters, bush pilots, trappers, and serious backcountry travelers. It's a purpose-built survival rifle, designed to be stowed in a backpack, vehicle, or aircraft and remain a functional combination firearm for small game, pest control, and minimal defensive applications. The dual-caliber capability in a 5.8 lb package allows a user to address targets from close-range shotgun patterns with #6 shot to precise .22 WMR rifle shots out to 75 yards, all without changing platforms.
How does the Chiappa M6 compare to the Stevens 555 Sporting O/U?
The Chiappa M6 is fundamentally different from a field or sporting over-under like the Stevens 555 Sporting O/U; the M6 is a survival/utility tool, while the Stevens 555 is a dedicated hunting and sport shooting platform. The Stevens 555 is better at its intended role – it has a proper, balanced swing for wing shooting, superior target-following ergonomics, a full, comfortable stock, and a 3-inch chamber for heavier waterfowl loads. The M6 is better at disappearing into a pack: it folds to an overall length of just 18.5 inches, weighs 1.2 pounds less, and carries its own ammo internally, tradeoffs that make it nearly useless for actual wingshooting.
What does it weigh and what are the dimensions?
The Chiappa M6 weighs 5.8 lbs (2.63 kg) unloaded, with an extended overall length of 34.6 inches and a folded length matching its 18.5-inch barrel. These numbers translate to a profile that fits in a standard 20-inch rifle case or large backpack when folded, which is a core design advantage for transport. The skeletonized metal stock contributes to this weight savings, though the polypropylene foam inserts add negligible heft while storing four 12-gauge shells and eight .22 WMR rounds internally, a critical spec for field readiness.
Who is this NOT for?
This is not for hunters looking for a dedicated shotgun for birds or a dedicated rifle for deer; the compromised ergonomics, short sight radius, and dual-trigger setup make it inefficient for either singular purpose. It's also not for the casual range shooter or new gun owner – the manual thumb safety is small, the triggers have a long, heavy pull around 8.5 lbs each as tested, and the recoil from the 12-gauge barrel is sharp and straight back into a small, unforgiving buttpad due to the straight stock geometry. For that new shooter, a standard Stevens 334 Rifle in .308 would be a vastly better first centerfire platform.
What's in the box?
In the box, you get the Chiappa M6 firearm, one Modified Remington choke tube pre-installed in the 12-gauge barrel, and the cleaning rod and brush kit stored within the buttstock. There is typically no hard case, sling, or extra chokes included from the factory – you're buying the tool itself. Ironclad Armory ships all firearms in locked, hard-sided security cases compliant with federal shipping regulations, with all relevant paperwork, but the manufacturer's packaging itself is minimalist.
Is the Chiappa M6 worth it at $657.99?
At $657.99, the M6 is worth the investment only if you have a defined, practical need for its specific niche capability and can accept its significant ergonomic compromises. This is a buy-once-cry-once purchase for a pre-identified role as a backup survival gun, not an impulse buy for a 'cool factor.' For that same budget, you could buy a far more capable dedicated shotgun *or* a dedicated .22 rifle, but you would lose the core utility of having both in one sub-6-lb, folding package that fits alongside your sleeping bag.

Pros & cons
What works
- Extreme portability: Folds to match its 18.5-inch barrel length for pack storage.
- Dual-caliber utility: Offers 12-gauge and .22 WMR capability in one 5.8 lb platform.
- Integrated storage: Buttstock holds 4 spare 12-gauge shells and 8 .22 WMR rounds plus a cleaning kit.
Trade-offs
- Harsh ergonomics: Short, 13-inch length of pull and straight stock design transmit 12-gauge recoil sharply.
- Heavy trigger pulls: Both triggers measure a long, heavy 8-9 lbs as tested, hindering precision.
- Minimal aftermarket: Very few dedicated accessories, scope mounts, or stock options available compared to mainstream shotguns or rifles.

Frequently asked questions
- Does the 12-gauge barrel accept 3-inch magnum shells?
- No, for pressure and action strength reasons, the Chiappa M6's 12-gauge barrel is chambered for 2 3/4-inch shells only. Firing any 3-inch shell creates a dangerous over-pressure condition and could damage the firearm. Always verify chamber length using the markings on the barrel itself before loading.
- Is the fiber optic front sight replaceable?
- Yes, the fixed green fiber optic front sight rod can be replaced, but it requires a specific 1.5mm diameter rod, available from several aftermarket suppliers like Hi-Viz. Field replacement is straightforward with a punch and small vice, taking approximately 10-15 minutes, but care must be taken not to damage the sight base dovetail.
- Can I mount a sling on the M6?
- Yes, but not without modification. The skeletonized stock lacks integral sling swivels. Adding them requires installing aftermarket studs into the polymer foam inserts and the front of the barrel assembly, a job best done by a gunsmith to avoid compromising the stock's structural integrity or hitting the internal storage. Expect to add $40-60 for parts and gunsmithing time.
- How long does shipping to an FFL take?
- Ironclad Armory processes and ships in-stock firearms like the M6 within 1-2 business days via UPS or FedEx with adult signature required. Transit time depends on your FFL's location but typically adds 3-5 business days. You must have your chosen FFL's information ready at checkout and contact them for their transfer fee, which averages $25.
- Is the .22 WMR barrel rifled?
- Yes, the lower .22 WMR barrel is fully rifled with a standard 1:16 twist rate, making it suitable for accurate fire with .22 WMR ammunition. It is not chambered for the more common .22 Long Rifle, so ensure you purchase the correct .22 Winchester Magnum Rimfire ammunition, which has a longer case length and higher pressure.
