In the United States, there is no federal law governing the ownership of crossbows. However, individual states have their own laws and regulations regarding crossbows. It is important to check with your state's wildlife agency to see if there are any restrictions on owning a crossbow. Some states allow anyone over the age of 18 to purchase and use a crossbow, while others have more stringent requirements. For example, in California, you must have a hunting license to purchase or use a crossbow for hunting purposes. In New York, you must be 21 years of age or older to purchase a crossbow.
Crossbows are becoming increasingly popular as both recreational and hunting weapons. They offer many benefits over traditional bows, including increased accuracy and easier cocking and loading. If you are interested in purchasing a crossbow, be sure to check with your state's laws and regulations first to ensure that you can legally own one.
