Notice the trigger is pulled once. 17 rounds shot in less than 3 seconds. Now imagine an assault weapon with an extended clip with a conversion device on it. This is why we need more laws and stiffer penalties for the manufacturing, selling, possession, and use of conversions devices. | Randall Woodfin | Facebook
