Me and that big screw have a history. Back in my newbie days when I was fresh on the HK teat I fought with one of those stocks for a half hour before I discovered the butt plate actually did come off and that there was a screw behind it. This was darn near pre-internet days, HKpro must have been an infant, Hesse was the only option for G3 receiver, and I had just aquired my first HK type. Those were the days. I don't even think SW had anything more than a cast prototype at the time and the clone industry was just a gleam in TB's eyes.
That reminds me. To those that make this board happen, thank you. This place is a most valuable source of info and without it many of us would be a lot less HK smart.
