Out here it is not hard to find a place to shoot 1000 + lots of them , When I built these I used AR 550 1/2 thick the frames are 1 1/2 muffler tube they are easy to set up and work great black with a white or orange dot works best , My little shooting buddy Noah shot them out to 660 yards with a 30X39 AI of mine I was Sooooooo Proud of him , He shoots 100 and 200 yards with a 22 LR let me tell you he does not miss much . I guess that is what happens when grandpa has let you shoot sense you could set at a bench
