Flat band power bands for Wrist-Rocket® flat band models. All our flat bands come with twin band double tapered bands for greater efficiency and speed plus our accurate, easy loading pouch the HVPC (Hyper-Velocity Posi-Center pouch). The Black Mamba™ are our standard medium power bands. The Stryker™ bands are high power and extra durable. Please note that the high-powered slingshot Stryker™ flat bands are too thick to be used with the Pipper™ sight. TNT™ bands are natural bands and are currently our fastest bands available.
