Right , all I saw was 501 , trust us, the most accurate armor available., total B.S. I purchased the armour then went to the 501 sites, totally the wrong order. All I can do is learn from the situation and modify the armour. I sent them an email the other day, asked , what type of plastic are you using for your armour? They replied with, " our manufacturer will not disclose the actual material used " like its a secret or something, I then asked , what is actually reduced with the reduced size armour, they responded with , " calfs , shins and forearms."
Lesson learned. Still awaiting my slot with TM....
