The Rossi RS22 is a semi-automatic rifle chambered in .22 LR (Long Rifle). It is manufactured by Rossi, a Brazilian firearms company known for producing a variety of firearms including rifles, shotguns, and handguns.The RS22 is designed to be a lightweight and affordable semi-automatic rifle. It typically features an 18-inch barrel, which refers to the length of the barrel from the breech to the muzzle. The .22 LR chambering makes it suitable for various purposes such as recreational shooting, plinking, and small game hunting.

As a semi-automatic rifle, the RS22 utilizes a self-loading mechanism, which means that each time the trigger is pulled, a round is automatically chambered from the magazine, the spent casing is ejected, and a new round is ready to be fired. This allows for relatively quick and continuous shooting.

The specific features and specifications of the Rossi RS22 may vary, so it’s recommended to consult the manufacturer’s information or the owner’s manual for detailed specifications, maintenance instructions, and any other relevant information about the firearm.
