Reactive steel targets are a blast to shoot at. Our hostage target kit features an AR500 swinging paddle that measures 5" x 3/8" that "locks in" to the hostage target mount so it won't jump out of the mount. Install with couple of bolts and within minutes you will be hitting the "bad guy". This target add-on is rated for use with most pistol and rifle calibers. AR500 Target Solutions' precision CNC- laser cut targets are rated to 3000 fps at 100 yards and made in the USA. ***Fitment- For use with rangetime 12x20 and 9x20 silhouettes. 2x4 mount/t-post mount is not included, mounts bought before 07/2020 will have to have holes drilled to mount the hostage target mount. New 2x4 mounts, t-post mounts are pre-drilled. Buyer assumes all responsibility for the use and misuse of the purchased targets.
