Well let's call this an "Olive Branch" until I can revisit a couple of topics down the road. I'm enjoying this time off; World Cup, Body Armor
research and most importantly catching up with the family. X-Men with the granddaughter on my weekend coming up-well that's just too cool (We got that THOR thing covered too.)!!
So anyway very good and accurate site and has been a good reference for me on occasion. Linked you below to his "about me page" which I've verified in the past. Research doesn't always start with the content it should start with the source. Or my Rule #1. Site is easy to navigate even for a
"Devil Dog" like you!?!

It'll cover all your weapons on the list. I lost another good Russian site when my system went down last Winter if you need it let me know and I'll try to recoup it for you.
