Fits in almost any full stock weapon and most M4 foregrips, crane stocks, and many MP5 types. Also will fit most AKs if you install it longways. Only use an approved LiPo charger. Smart chargers or anything else that hooks directly into the Tamiya connectors themselves will ruin these. We also recommend using a protective LiPo sack when charging.
