Umarex Steel Storm BB Airgun - 300 round reservoir & 6 Shot burst.. Damaged my room door

This is my detailed review on the Umarex Steel Storm BB Airgun. I'll be unboxing and testing the gun. I purchased the combo package from Walmart for about $105. It includes the Umarex Steel StormBB Airgun, a Copperhead 6,000 rounds, and Crosman CO2 cartridges 40 count. I tried bottles of water, empty and full as targets about 20 ft away. Unfortunately I didn't hit both bottles but I damaged my room door badly, check it out. Thanks for watching and share your thoughts.
