Gents - A few years back I bought my son a NIB GSG 522 from a FFL friend of mine. It's the style which has the large rubber? forearm and large barrel cover (fake suppressor). After seeing the pictures in owners manual and teaching him to clean it, he said he wished it had the smaller forearm and barrel cover. I've located multiple sources for a forearm, but no such luck on the smaller barrel cover (on the LW carbine style). I've checked HK parts, EBay, GPC, GB and a few other places and even called HK parts, no luck. If anyone is familiar with these models and knows of a source for parts fro these, I'd appreciate it. It seems that these are now discontinued, so I'm guessing it will be a secondary market find, if I'm lucky. Both him and I would be plenty happy with a nice used one as well. Greatly appreciate any help - Thanks Bill in MA
