Dave,
I think that plate is the one that Gary Roberts recently tested and it did very bad.
Here is part of his quote:
To say we were surprised by these findings, would be the understatement of the year...
The DBT 5 mm Ultra Concealable Level “3+” plate did NOT behave like typical good quality steel plates we have previously shot and acted more like a ceramic plate, with significant cracking with each hit. Contrast this with the 6 mm AR500 steel plate that absorbed 31 hits without any cracks or fractures of the plate. It is possible that the DBT plate could have been manufactured using improperly heat-treated Chinese steel, which can be overly brittle and is known to crack. We called DBT for an explanation; the DBT rep we spoke with stated the vendor who fabricates the plates claims they are indeed “steel”, but the DBT representative was unsure of the exact specifications. DBT reported that they will research this issue and get back to us.
WARNING !!!
At this point in time, the substandard performance and inability to sustain multiple hits demonstrated by this current production DBT “Ultra Concealable Level 3+” 5 mm “steel” plate warrant that extreme caution and care be exercised when contemplating the use of this armor for LE or military use.
