I recently bought a new vest from Blackhawk and steel plate. The armor is designed to be "quick release" and is thus a CIRAS vest.
The plate is "stand alone", so it's designed to stop bullets and shrapnel without the addition of any "soft" armor. This plate is NOT a rifle plate, it is only designed to stop pistol bullets. Rifle plates are often made of ceramics, which aren't as durable as steel plates. Life is full of trade-offs...
I added some burlap strips to the molle front to break up the outline.

Here's the back of the vest, I haven't decided if I'm going to add burlap yet... I might just add burlap to a camelbak and/or assault pack and "marry" them together.

Here's the steel plate. It's 10 by 12 inches and weighs a good five pounds. Nobody ever said that becoming bulletresistant was fun or lightweight.
