Inexpensive BB guns are widely available from a number of retail outlets. They can be found online or at traditional brick-and-mortar locations. Prices will vary depending on models and available accessories.
While the definition of an inexpensive BB gun depends on what a buyer is willing to spend, specialty retailers like AirRattle and HobbyTron offer BB guns at prices as low as $1.50, as of 2014. Other retailers, such as Walmart and Amazon, offer a wide variety of fully functional BB pistols and rifles starting as low as $9. Another good option is eBay, where many new and used BB guns can be purchased for a few dollars.
