Krytac TRIDENT MK-II M PDW: BEU™ Battery Extension Unit


The Battery Extension Unit (BEU) is designed specifically for the Krytac Trident MK-II M PDW  used to connect a larger battery to the gun while keeping it external to the gun's body. This allows players to use higher-capacity batteries for longer gameplay without compromising the aesthetics or functionality of the airsoft gun.
