Description
Swiss Arms 4.5mm/.177 Steel BB Pellets (3000 Rounds)
This is the larger 3000-round pack of Swiss Arms steel BBs, sold under Cybergun reference 883000. They are 4.5mm (.177) steel balls for air guns built to fire steel BB ammunition, such as many CO2-powered pistols and rifles. If you shoot regularly, the bigger pack works out more economical than buying smaller packs over time.
Swiss Arms is a Cybergun brand with a long list of replica air guns designed for this kind of ammunition. Keep in mind that these are steel BBs for air guns, not 6mm plastic airsoft BBs, and the two must never be mixed up.
Shooting safely
Steel BBs are hard and can rebound from solid surfaces, so always shoot into a purpose-made BB trap or dense backstop, set up your range so nobody stands to the side or behind the target line, and keep well away from windows, metal and stone. Eye protection is essential for anyone nearby.
Getting the best from them
Load the BBs as your air gun’s manual describes, whether into a stick magazine, a speedloader or a reservoir. Keeping the magazine and BBs dry and clean helps them feed reliably and keeps your shooting consistent.

Care and maintenance
