About this item

• PRECISION STEEL CONSTRUCTION: Each BB is 4.5mm and weighs 5.23 grains for consistent weight and diameter from the first round to the last. Tight tolerances mean fewer jams and more predictable performance.
• BLACK-COATED FOR SMOOTH FEEDING: The black coating cuts down on surface friction so BBs feed cleanly through your action without hanging up. Less friction means less wear on your airgun over time.
• 1,000-COUNT EZ-POUR BOTTLE: The wide-mouth bottle makes reloading fast and controlled. No dumping half your supply on the ground trying to top off a reservoir. Fits standard speed loaders and most reservoir-style airguns.
• BROAD COMPATIBILITY: Works with most 4.5mm BB air rifles and pistols. Optimized pairing with Crosman BB airguns, but reliable across most .177 BB platforms. Great for target practice, plinking, and skill development.
• INNOVATION STARTS HERE: In 1924, Crosman introduced the first pneumatic pump airgun, delivering power without powder. Nearly a century later, Crosman remains a worldwide leader in airguns, ammunition, and shooting optics.

Crosman Black Widow BBs are steel 4.5mm ammo that's built to shoot the same every time. Each one weighs 5.23 grains and they're held to tight dimensional tolerances, so you're getting the same size and weight whether it's your first BB or your thousandth. That kind of consistency makes a real difference for accuracy and keeps your airgun feeding smoothly. The black coating on each BB reduces surface friction as it moves through the action. Less friction means cleaner feeding, fewer hang-ups, and less wear on your airgun's internals over time. It is a small detail that adds up across thousands of rounds. The 1,000-count EZ-Pour bottle has a wide mouth designed for controlled pouring directly into reservoirs or speed loaders without making a mess. If you have ever tried to fill a reservoir out of a bag or a cheap bottle, you know how much this matters. Black Widow BBs are compatible with most .177 BB air rifles and pistols and are the recommended pairing for Crosman BB airguns. They're perfect for running paper targets, working on fundamentals, or just putting rounds downrange without any fuss.
