Description
The idea behind the M6 goes back to the old military survival guns issued to aircrews, and Chiappa's version takes that concept and gives it a proper update. You get an 18.5 inch 12 gauge barrel stacked with an 18.5 inch .22 WMR barrel, each fired by its own trigger. No selector switch to fumble with, just pull the trigger that matches the job. Shot shell for birds and close work, a flat shooting rimfire magnum for small game at distance. Push down on the trigger guard and the whole gun breaks open and folds in half, which is what makes it such an easy companion in a pack, behind a truck seat, or stashed with your camp gear.
The M6 Stock Carries Its Own Supplies
The skeletonized steel buttstock wraps around a molded polypropylene foam insert that holds three 12 gauge shells and five rimfire cartridges, so a reload is always riding with the gun. A cleaning kit tucks into the stock too, which is a smart touch for a firearm built to live outdoors. All that utility comes in at roughly 5.8 pounds, with an overall length of 34.6 inches when it's open and ready.
Sights and Rails Done Right on the Chiappa M6
Up top you get an adjustable M1 carbine style rear sight paired with a fixed red fiber optic front, a combination that's quick to pick up even when the light starts fading. Picatinny rail sections on the receiver give you room for a small optic, light, or laser if you want to dress it up. The shotgun barrel has a 3 inch chamber and threaded Rem Choke style muzzle, and a modified choke tube comes in the box, so you can swap constrictions to match the load and the task.
For ranchers, pilots, campers, and anyone who likes the idea of one simple gun that covers a lot of ground, the M6 is a hard combination to beat.

Frequently Asked Questions
Does the Chiappa M6 accept choke tubes?
Yes. The 12 gauge barrel has a 3 inch chamber and is threaded for Rem Choke style tubes, and a modified (MC-1) choke ships with the gun. That means you can run tighter or more open constrictions depending on whether you're patterning for small game, birds, or close range work.
How does the M6 fold, and how compact does it get?
Press down on the trigger guard and the gun breaks open and folds in half at the hinge. Folded, it's compact enough to slide into a backpack, duffel, or behind a truck seat, and at roughly 5.8 pounds it won't weigh you down on the way in.
Can I mount an optic or light on the Chiappa M6 Combo?
You can. The receiver carries Picatinny rail sections that accept red dots, small scopes, lights, or lasers. The included M1 carbine style adjustable rear and fiber optic front sights work well on their own, so glass is optional rather than necessary.
How do you choose which barrel fires on the M6?
Each barrel has its own dedicated trigger, so you simply pull the one for the barrel you want. There's no selector to flip, which keeps things fast and simple in the field. The rear trigger and front trigger correspond to the 12 gauge and .22 WMR barrels, and you can fire them in whichever order the situation calls for.
