well let me explain a few things about that really bad you tube video, it seems that you tube is becoming like facebook, any idiot can post.
1. yards is very, very close when it comes to stopping a rifle round.
2. The person has no back stop, anyone that knows anything about armor knows you have to have the product against a soft back stock, blastic gel, or even a human shaped dummy.
3. those plates are flat 1/4 inch AR500, they just make the grade for rifle plate. "if" they are heat treated and stress relieved correctly.
4. NIJ standard is from 25m for all hard armor.
5. Those plates are from AR500.com , who were found out this summer to be getting there steel fro ma mill in mexico, due to so much demand for "cheap ar500 plates" but they still say made in USA. many, many people are very unhappy with that that company.
To compare that with what we are offering.
1. made in Canada but an ISO 9001 ect company that provides plate defense contractors such as GD.
2. 3/8th inch think custom HTSR AR500 to our spec.
3 Cut via waterjet as to not stress and over heat the edge of the plates, then hand ground and finish edges.
4. single formed curve on a 50 ton press, not triple punch formed on a die as that would stress the metal.
5 re heat treated and stress relief after forming the single curved.
6 we apply a US mil spec anti spall coating, as im sure others do, but this is not your standard truck bed liner, we heavy cote the plates to help with the spall, not just cote it to look good.
The only down side with our plates are weight, and the cost to make them in Canada, but they are still 1/2 the cost of ceramic plates, which you can drop and damage.
