Available in a 4 pack, the Do-All Outdoors Pigeon Perch is constructed of the technologically advanced Impact Seal material. The bullet passes through the self-healing material with minimal damage. This material is rugged enough to handle the repeated punishment from all calibers of rifles and handguns as well as BB and pellet guns. With a competitors target holder, one missed shot could mean the end of your target practice. Unlike plastic holders, this material will not crack or break. To use, insert the rod into the bottom of the holder. Stick the Pigeon Perch into the ground in front of a safe backdrop. Slide the clay target firmly into the U-shaped holder. The Pigeon Perch works best with standard 4.5 inch targets.
