Aguila ECO airsoft grenades are more reliable and higher quality than most of the airsoft grenades on the market today.
Other airsoft grenades are designed so you have to partially unscrew the base to reset it. The problem was you could easily unscrew the base too far and release half a dozen tiny ball bearings that are almost impossible to get back in. On these grenade all you have to do is push a button in and you are ready to rock and roll again.
Most of Aquila ECO grenades are modeled after real grenades in shape, size and color. This one is modeled after the M433 anti-armor fragmentation grenade.
