Not to be a smart ass, but good luck. The GSG-5 is no longer being made. What dealers have in stock is it. They pop up on gun trader every now and then. Supposedly Umarex (sp?) has contracted with HK to make the next batch, dont hold your breath though, they screwed up the Colt M4 pretty good....
Austin Gun Liquidators in Pflugerville has a couple.
yeah I just wanted to make sure you knew what you were getting into is all. I as you most likely have shot thousands of rounds of 22 in my life and I have just come to the conclusion that unless you get top dollar ammo, keep your weapon very clean, and use high quality 22 platforms you are going to get a lot of jams. Maybe I just have bad luck.. but I have a walther p22 I rarely shoot and would not attempt to sell as it jams all the time.. and the list of other .22's ive shot that jam just go on and on.. My favorite .22 is a bolt action with a 10 round clip sucker works every time!
