bb gun
Definition
Noun: * An air gun that fires small spherical metal projectiles, typically 4.5mm (.177 caliber) in diameter, known as BBs. The projectiles are propelled by the force of compressed air or carbon dioxide (CO2).
Usage
The term "BB gun" specifically refers to the type of airgun and its ammunition. It is a common noun. * He received a BB gun for his birthday and practiced target shooting in the backyard. * Safety glasses should always be worn when using a BB gun. * The BB gun uses compressed air to fire the small metal balls.
Advanced Usage
- The "BB" in "BB gun" originally stood for "ball bearing" or the size "BB" used in shotgun shell classification, though modern BBs are not precisely the same.
- While often considered a beginner's or training firearm, BB guns can be dangerous and require the same safety considerations as more powerful weapons.
Variants and Related Words
- Air rifle / Air pistol: Broader terms for guns that propel projectiles via compressed air; some air rifles can also fire BBs, but many fire larger, differently shaped pellets.
- Pellet gun: Typically refers to an air gun that fires diabolo-shaped pellets rather than spherical BBs, often with higher precision and power.
Synonyms
- Air gun (specific type)
- Air rifle (when referring to a long-barreled BB gun)
Notes
- Not a Synonym: "BB gun" is not a general synonym for all airsoft or toy guns. Airsoft guns typically fire 6mm plastic pellets, and toy guns are generally non-projectile or use softer materials.
Noun
-
an air gun in which BBs are propelled by compressed air
