I may suggest against taking him out to shoot your AR.
Yeah, lucky I don't have one, and I probably never will. Not if he can do anything about it. His evaluation of the M16 included a plethora of profanity, and repeated use of the term "bolt override." He does, however, think that the M249 is the coolest thing since sliced bread. He says that it's not perfect, but it's a good step.
Ironically enough, he is just itching to shoot his "baby," the Romanian SAR-1. I would've thought he'd be soured on AKs, but I guess he still loves his.
I will be sure to pass along your gratitude, although probably in liquid form
He tends to get embarassed when he hears people talk like that. He'll usually just look at the floor when people thank him for what he's done, but I have learned enough to know that you usually have to earn humility like that. Grandad instructed me to avoid using "the V-word" to describe him, and that if he wants to talk, he'll talk. I think I'm just going to enjoy pizza, video games, and lots of beer with my brother, and worry about the military stuff some other time.
Thank you for your kind words, guys. I know he'll be glad to know that people are grateful for what he's done.
