Has anybody come across this construction for Level III & Level IV ballistic plates? I found several sellers advertising it, including:
http://www.safezoneballistics.com/gear.html
http://www.blucoreshootingcenter.com/blog/?p=2195
I wonder if this is simply AR500 steel with fragmentation capture material applied? Though it is Level IV, which I didn’t think AR500 could provide.
Uh…the bottom link states: “The KDH Guardian 4 plate is a level IV stand alone plate. It is a single curve, ceramic plate and is stand alone rated up to level IV.”
When I emailed them to find out whether it’s multi hit our not, they said the plate is not ceramic (and hence multi hit). Perhaps I should press them to clarify that response.
Plates in the first link are not the same as the plates in the second link.
I emailed folks at Blu Core, we’ll see what they say. The reason I mentioned in Safe Zone was because they also describe their plates as ABMM (w steel).Is that a meaningful term of art, or just marketing talk?
Doesn’t exactly tell us much about construction or capability, does it?
No, it doesn’t. 
Soo…I called KDH, and this is what they said: It’s all ceramic Level IV plate, manufactured by Highcom, 7.3 lbs, it is multi-hit capable against SS109 (stops 14 out 15 shots) and they didn’t know how it would perform against 3000+ ft/sec 5.56 projectiles.
The KDH/Highcom plate in the second link is a well known product; I am referring to the info in the first link…
