Have a more explosive training session with these Big Blast Inflator Caps from UMAREX. These caps fit over all standard sized cola bottles (3-liter bottles excluded) and water bottles that have a colored cap. Tightly screw on a cap and pump air into the bottle using a bike pump up to 80-150 psi, and you're ready to go! The release of pressurized air into the normalized atmosphere creates a very loud “BOOM”, ensuring you know when you've hit your target and adding more fun to target practice. These caps are 100% reusable and come in a convenient mesh carrying bag so you can easily keep track of all 10 caps. The included retrieval string can be tied to the cap to be held down and picked back up after explosion. Unless you live far away from your neighbors, these are not backyard friendly as they will cause a loud explosion!! Pressurized bottles can be dangerous, extreme caution is recommended when handling and inflating. Never remove the cap while the bottle is pressurized and never reuse a damaged bottle cap.
Note: Pressurized Bottles Can be Dangerous, Use Extreme Caution During Handling and Inflating; Gloves and Eye Protection Recommended UMAREX. Stay Back at Least 30 Feet from Target. Keep Children and Pets Away.
