The oper8 stick batteries are just the perfect size to fit into most airsoft AEGs and can easily be installed in most front wired M4 and AR platform handguards, crane stocks, stock tubes, AK variants, MP5, MP5k, UMP and pretty much anything else! If you’re using a crane stock, why not double them up and keep a spare with you at all times.
Dimensions: 12mm x 20mm x 120mm Connector: Deans or Mini Tamiya

Deans connectors are recommended for a much more consistent and reliable connection to your AEG, whereas the Tamiya connectors can wear down over time.
