Chiappa Firearms M6 Chia 500.188 12Ga/22Lr Ct 18.5
The Chiappa M6 Chia is a compact break-open rifle-shotgun combo built for versatility in the field. Chambered in 12 gauge and .22 LR, this dual-barrel over-under gives you shotgun power and precision rimfire in one 18.5-inch package. It's the kind of pragmatic tool that appeals to hunters who want options, survival-minded shooters, and anyone who appreciates clever engineering in a lightweight, packable platform. At 5.8 pounds, it won't tax your pack or your shoulder on a long day.
The folding break-open action keeps things simple and reliable—no springs to foul, no moving parts to bind. Each barrel gets its own trigger, so you can choose your shot without fumbling with selectors. The shotgun barrel wears Rem Choke threads with a Modified choke installed, and the .22 barrel rides with an M1-style adjustable rear sight for precision work on small game and target shooting. Manual safety keeps you in control.
Where this gun gets interesting is the quad Picatinny rail forend, giving you room to mount lights, lasers, or other modern accessories on either barrel. The PPS foam and steel stock absorbs recoil while keeping weight down, and the extractor pops cases out cleanly after each shot. Total length runs 34.6 inches, making it maneuverable in thick cover or tight spaces. Blued steel construction means it'll age gracefully with honest use.
This is a gun that doesn't overthink its job—it shoots shotgun slugs or birdshot, then flips to .22 for precision. That combo appeal, compact handling, and rail-ready design make it a natural for hunters, sport shooters, and folks building a lean, multipurpose battery.

Frequently Asked Questions
Can I change out the shotgun choke on the M6 Chia?
Yes. The shotgun barrel uses Rem Choke threads and comes with a Modified choke installed. You can swap in other Rem Choke patterns to match your game or load.
What sight options do I have for the .22 LR barrel?
The M6 Chia comes with an M1-style adjustable rear sight on the .22 barrel for field accuracy. The quad Picatinny rail on the forend also lets you mount a scope, red dot, or other optics if you prefer that setup.
How does the folding action work?
The break-open design folds for compact carry and storage. You simply open the barrels, load one round into each (shotgun on top, .22 on bottom), and close. The extractor removes spent cases when you break open again.
Is this gun suitable for hunting?
Yes. The dual-barrel setup makes it practical for hunters who want shotgun versatility (slugs, buckshot, or birdshot) on one barrel and precision .22 capability on the other—useful for small game, upland birds, or survival-oriented hunting. The compact 18.5-inch barrels and lightweight build suit field carry well.
