I bought this off Ebay, the first one was missing some hardware so I contacted them and showed them pictures of the messed up UPS box. I just wanted the missing hardware, they weren't interested in that, they sent me another complete target. I then bought hardware to complete the original. When I ordered them they were noted as AR500, these things don't note that anymore, I doubt mine are, but I can't tell, don't even know how to tell.
So I have two of them, I bought 4" plates extra from Amazon to use on the one I put at 11yds, the target comes with 8" plates, the 2nd one I have at 30yds with the 8" plates.
These sit at my personal range in my backyard, so they aren't seeing tremendous abuse, but they've been absolutely fine, no dimpling, no bending, no nothing, motion is good.
I shoot them with my 9mms and I shoot, primarily, 147gr FMJ flat nose for practice ammo. All pistols, no carbines.
Been thinking of blasting one with the 500 S&W just to see what happens, the little 4" plates are more fun, they really fly when you hit them, the 8" just tend to drop straight down. Measured the one 4" at 15', it flew back. The 4" are very noticeably smaller though, good practice, difficult.
Ordered it, "just to see," and ended up with two like noted, they've been great. My only rifle is a 458 lott, won't be testing them with that, but if you want me to pop one with the 500 S&W, let me know, I'll put an 8" plate back in the 11yd target and blast it.
