American "crazies" playing with their toys. God bless'em. Somewhere in there I think saw an HK-91/G3 near the end. I used to have one of those back in the 80's until I sold it to another guy who was working at Borland with me at the time. Put a box of ammo through that thing and your shoulder felt like it had been beaten with a sledge hammer.
H/T to some commenter over at Jane Galt's place
