Elite Force Airsoft BBs are packaged in a unique bottle with a screw-on cap, much like a soda pop bottle, that makes storage, transport, and loading simple. The 6mm BBs for airsoft guns from Elite Force have been tested successfully in many variants of mid- and hi-cap airsoft magazines. That testing combined with the overall consistency in size and polish have proven their precision reliability. EF airsoft BBs are made of an excellent formula for competitive airsofters and airsoft events. Elite Force FUEL Green Gas is made to power your gas-powered airsoft rifles and airsoft pistols including your handguns that use drop-free green gas airsoft magazines.
