I remember very prompt delivery, thanks... Personally, I much favor using 2x4 gong holder frames and these Atlas hooks simply work smarter and easier than bolts w/springs. They hold the targets high, allow the right amount of visual movement feedback, can slide/adjust along the 2x4, and have a discreet/low profile so do not cause hangups in the back of my truck. Each of my 6 total hooks have taken pistol FMJs straight on without a scratch. Very pleased!
