One of the most asked questions about an airgun is, "How loud is it?" Valid question. Umarex USA has quite a few air guns that are very quiet. In fact, one of the quietest air rifles is the new Umarex Fusion 2. The Gauntlet .22 caliber PCP rifle is another quiet gun. Airgun silencers are often asked about and that's where the Umarex SilencAir muzzle device comes into play. It helps to deaden the sound of an airgun pellet leaving the barrel. A .22 caliber air rifle is usually a good choice if you want a quiet rifle as are CO2 rifles and CO2 airgun pistols. Do remember, the pellet trap or BB trap is sometimes the key to a quiet shooting session that you don't want your neighbors to know about. With most quiet airguns the pellet smacking a hard backstop will be louder than the airgun itself! You might want to avoid those tin cans.
