I bought mine because I knew they lost the suite with HK. My GSG-5 is a blast to shoot and as long as you don't user the magazine as a handle when shooting, the thing is ultra reliable and accurate to boot. I just finished putting the ATI collapsing stock on mine and it makes it look ultra cool. I also put a Leapers 4x scope on it and will sight it in this Friday. The iron sights are pretty good though.
