Full-auto BB guns are the most fun you can have in the backyard without a range membership: .177 steel BBs, select-fire fun, and prices that make them genuinely giftable. These ten came from friends asking for Christmas picks, so every one is a rifle (plus one compact pistol) that is fun out of the box. Every link below was verified against its exact Amazon listing before it earned a card.
Safety first, always. Always wear eye protection, never point any airgun at people or animals, and treat every BB gun like a real firearm for handling and storage. Check your state and local laws before ordering — some sellers restrict shipping by state and require an adult signature, and CO2 cartridges and BBs are usually sold separately.

The modern tactical pick with a trick up its sleeve: semi-auto or a 6-round burst, fed by a 900-BB reservoir in the drop-free mag. Two 12g CO2 cartridges live in the collapsible stock, and flip-up sights plus full rails leave room for optics. Around 400 fps.
