Great airgun fun. When the colored kill zone is hit, the target falls. To reset, simply pull the cord. Target and kill-zone reducers are solid steel construction. Includes anchoring stakes and reset pull cord. While Gamo does not provide a max velocity or energy for this target and clubs usually limit guns to 20 ft-lbs or less. You will damage the target (and possibly the mechanism) if you shoot at it with alloy or non-lead pellets, more powerful guns or larger-caliber pellets. Gamo states that you should place the target no closer than 25 yards.
