So you activated your airbag, either during a slide or an intoxicated demo for your friends. Either way, now it's time to refill your cylinder with the BCA Extra Consumer Refill Kit. You'll need this if you travel with an empty cylinder and need to refill it at your destination, too. The kit contains a 5/32" Allen Wrench, toothpick, 5 O-Rings, and grease - enough for five refills.
