I bought an AR500 silhouette target and didn’t realize at the time that the ones with two mounting holes would be very difficult to find a mounting bracket for it. After weeks of searching, I found the Atlas T-post double hook mount and was very pleased to see that it was adjustable to accommodate various sizes of targets. Since I’ve had it, I’ve only been able to run about 50 rounds through my pistol but I can say that it works great. The t-post hanger holds the AR500 target at a perfect angle to deflect the rounds down to prevent and shrapnel from splashing back at the shooter. I was doing double tap drills at 7 yards and had no issues. The target never moved and one of my shots hit the hook of the hanger but did not cause any damage. You will not be disappointed in this hanger.
